Definitions

  • the invention relates to a method for producing thick steel slabs with a casting thickness exceeding 360 mm and a casting width exceeding 1000 mm in a continuous caster.
  • a continuous caster of the "vertical system or vertical bending system” type which has a long vertical strand guide part with a subsequent bending and straightening zone, is known from the publication of Dr.-Ing. Klaus Harste et al; "Construction of a new vertical caster at Dillinger Wegtentechnike”; MPT International 4/1998; Pp. 112-122 already known.
  • This casting plant the layout of which is shown in FIG. 8, enables the casting of steel strands with a casting width of 1400 to 2200 mm and a casting thickness between 230 and 400 mm.
  • an arc continuous caster is already known for casting a steel strand with a strand thickness in a range of 200 to 300 mm, with which slabs of good quality can be produced.
  • the metal strand is formed in an arched mold with a radius of curvature which lies in a range from 2.0 to 4.9 m and which corresponds to the radius of curvature in a first zone of the subsequent strand guide.
  • the steel strand is straightened again, which inevitably results in the formation of a trapezoidal cross-section of the steel strand.
  • This cross-sectional distortion becomes greater the greater the strand thickness and the smaller the radius of curvature in the curved mold and leads to quality problems in the subsequent rolling in the heavy-plate mill.
  • the object of the present invention is therefore to avoid the disadvantages of the known prior art and to propose a process for the production of thick steel slabs, the production of high quality steel strands and slabs with a casting thickness exceeding 360 mm with good internal quality, low susceptibility to cracking and extensive format accuracy is guaranteed.
  • Another aim of the invention is to keep the investment and operating costs low while the productivity of the casting plant is high.
  • an arched mold does not have the good conditions known from a straight mold for the introduction of the steel melt into the mold and for a uniform strand shell formation.
  • the need for a strand bend in a bending zone immediately after or at a short distance from the mold can largely or entirely be avoided. This reduces the risk of cracking in the edge or surface area of the strand.
  • a system with a curved mold has a lower overall height compared to a system with a straight mold with the same strand guide curved radius.
  • the curved mold used in the proposed method can be designed with a straight inlet section and a curved outlet section, the outlet section having a curvature corresponding to a predetermined mold bending radius.
  • the mold cavity of the arched mold can also be continuously curved with a constant mold arc radius. Variations of these embodiments are also possible.
  • the cast steel strand is transferred from the arc mold into the arc guide of the strand guide free of bending forces.
  • the mold arc radius of the cast steel strand when exiting the arched mold can be larger or smaller than the strand guide arc radius in the strand guide and the cast steel strand in a bending zone within the strand guide from the mold arc radius of the cast steel strand when exiting from the Curved mold to be bent to the strand guide curve radius in the strand guide.
  • This embodiment opens up the possibility of keeping the cast steel strand constant over a certain distance after its exit from the curved mold with the curvature impressed on it, which corresponds to the mold arc radius on the mold exit side, and then to make a strand bend to the strand guide arc radius within a bending zone or to carry out this bending process immediately after the exit of the steel strand from the arched mold.
  • the bending process is kept low when the strand shell thickness is still small.
  • Bending the cast steel strand down to a predetermined radius of curvature in a bending zone and bending back the cast steel strand in a straightening zone corresponds to the concept of known continuous slab casting plants and has proven itself as such. It is essential for the casting of thick slabs that both processes take place at times when the steel strand still has a liquid or partially liquid core, or it is necessary to regulate the cooling of the steel strand in the strand guide accordingly. With increasing strand thickness, the requirements for the most uniform possible cooling increase, which must necessarily be reflected in a temperature distribution that is as uniform as possible over the strand length and the strand width at a high temperature level, in order to ensure uniform elasticity of the strand and to avoid cracking as a result of temperature differences.
  • the desired temperature profile specified for the system control is determined by an entry surface temperature of the steel strand in the straightening zone of the strand guide.
  • the aim is to keep the steel strand, including the surface area, in a temperature range above the low ductility, which also minimizes the tendency to form surface cracks.
  • a system with a curved mold has a shorter strand length from the mold level to the straightening zone compared to a system with a straight mold with the same strand guide curved radius. Therefore, the time that the strand needs for this distance at the same casting speed is shorter than with a comparable system with a straight mold. Due to the shorter time available for cooling, it is possible to keep the surface temperature at a comparatively higher level. This minimizes the tendency for surface cracks to develop.
  • the proportion of the solid strand shell of the cast steel strand is a maximum of 95% of half the strand thickness during the re-bending phase in the straightening zone.
  • the aim is to mix the preferably partially solidified core zone close to the solidification point of the rod by reducing the thickness of the steel strand using a soft reduction or a dynamic soft reduction, thus achieving an improved microstructure in the core area of the slab and starting line segregation and porosity avoided.
  • a soft reduction in particular a dynamic soft reduction, is used on the cast steel strand in an area with a still liquid or partially liquid core of the steel strand with an adjusting device for strand guide rollers.
  • the cast steel strand is bent in a bending zone within the strand guide to an arc radius between 9.0 m and 15.0 m, held in a subsequent arc of the strand guide on this arc radius without further deformation and in a subsequent straightening zone within
  • the strand guide is straightened again starting from a curve radius between 9.0 m and 15.0 m.
  • this curve radius provides the best surface quality and minimization of cracks in the cast steel strand with simultaneous, precisely regulated cooling in these areas of the strand guidance.
  • the impact position of the coolant jets on the cooling of the cast steel strand Steel strand regulated at least in a partial area of the strand guide on the basis of a continuous determination of the temperature profile along the transport path of the steel strand and in normal planes thereto.
  • the amount of coolant applied to the steel strand in the strand guide up to the entry into the straightening zone is expediently regulated as a function of a predetermined temperature profile along the transport path of the steel strand and in a normal plane to it. This is intended to achieve a further increase in the accuracy of the temperature distribution over the surface of the steel strand.
  • the specified temperature profile takes into account the ductility properties of the steel grade to be cast.
  • a further stabilization of the cooling conditions is achieved if the controlled cooling of the cast steel strand takes place after the dry mode within the strand guide with the integration of peripheral-cooled strand guide rollers.
  • This avoids the need to take into account the cooling of the strand guide rollers as an essential element in dimensioning the intensity of the coolant application, or to align the intensity of the coolant application in individual areas with the needs of the strand guide rollers.
  • the strand surface temperature can be kept at a very high level, at least in the area up to the point where the steel strand is bent back.
  • the strand guide rollers are cooled almost exclusively by internal cooling of the strand guide rollers, the coolant being expediently guided through coolant channels in the roller jacket area as close as possible to the roller jacket surface.
  • non-metallic elements for example casting powder particles
  • the flow movement of the steel melt of the liquid core of the steel strand in the mold or in the area of the strand guide is influenced by an electromagnetic device.
  • an electromagnetic device In addition to an increased rise of the non-metallic accompanying substances to the bath level surface in the mold, there is a targeted mixing of the steel melt and a reduction in segregation tendencies.
  • the described method for producing thick steel strands is preferably used when the steel strand is cast with a casting thickness lying in a thickness range of 360 mm to 450 mm.
  • the metallurgical requirements and investment and operating costs of the casting plant are optimized if the exit-side mold arc radius of the arc mold is 8.0 to 20.0 m, excluding the specified value for the strand guide arc radius and the strand guide arc radius within the arc guide the strand guide is 9.0 to 15.0 m.
  • the cooling device in the strand guide is equipped with several independently controllable cooling zones across the casting width and / or with height-adjustable spray nozzles with controllable adjustment devices. This enables the strand edge temperature to be influenced in a targeted manner by regulating the amount of cooling water as a function of the width and / or by changing the distance between the spray nozzles and the steel strand surface and thus changing the lateral distance between the coolant jet and the steel strand edge.
  • One or more electromagnetic devices such as a stirring coil, for influencing the flow movement of the molten steel of the liquid core of the steel strand are arranged in the mold or in the area of the curved strand guide.
  • Peripherally cooled strand guide rollers are expediently arranged in the strand guide for supporting and guiding the steel strand.
  • the use of these peripheral-cooled strand guide rollers results in a significant decoupling of the different cooling requirements of the cast metal strand and the strand guide rollers, which are in direct line contact with the hot steel strand and are exposed to its radiant heat.
  • Figure 1 a schematic longitudinal section shows the structural design of a continuous caster for producing slabs from liquid steel for a casting thickness of 400 mm.
  • the continuous caster has an arched mold 1 with a curved mold cavity 1a. It is designed as an oscillating, internally cooled adjustable mold with wide side walls and narrow side walls and enables the casting of steel strands with different strand widths and possibly also different strand thicknesses.
  • the mold 1 is equipped with an electromagnetic device 2, such as a stirring coil or an electromagnetic brake, for influencing the flow movement of the steel melt in the liquid core of the cast steel strand.
  • a strand guide 3 adjoins the mold 1 and extends as far as a cutting device 4 designed as a flame cutting machine for cutting the steel strand into slabs.
  • the cast steel strand is supported and guided on its broad side walls in a narrow corset by driven and non-driven strand guide rollers 5 and diverted from a casting direction G determined by the mold arc radius RK into a horizontal transport direction T.
  • Groups of strand guide rollers 5 arranged on both sides of the steel strand are combined in strand guide segments 6.
  • the strand guide 3 comprises a series of successive sections with specific functions, the structure of which is essentially known.
  • the steel strand emerging from the mold 1 is transported along a circular arc with the strand guide arc radius RSt in a circular arc guide 9 and while maintaining this arc radius without applying any bending stresses.
  • the strand guide arc radius RSt here corresponds to the mold arc radius RK, which ensures transport without bending stress.
  • a straightening zone 10 following the circular arc guide 9 the steel strand is bent back and straightened.
  • the steel strand is then conveyed in a horizontal strand guide 11 to the dividing device 4.
  • the strand guide 3 comprises a series of successive sections with specific functions.
  • a curved strand support device 7 the steel strand emerging from the arched mold 1 is guided and supported in accordance with the mold arc radius RK without the application of bending stresses.
  • a first area of the strand support device 7 there is also a strand support with strand guide rollers 5 also on the narrow sides of the steel strand.
  • a subsequent bending zone 8 there is a progressive bending of the steel strand from the mold arc radius RK to the strand guide arc radius RSt of the subsequent arc guide 9.
  • the steel strand is transported further while maintaining the strand guide arc radius. The further transport of the steel strand takes place analogously to the embodiment in Figure 1 .
  • the cooling device 12 comprises, as in FIGS Figures 3 and 4 shown, between the strand guide rollers 5 positionable spray nozzles 13, which are independently adjustable in a normal plane N to the transport direction T at least in partial areas.
  • spray nozzles 13 provided with control valves 18 for regulating the amount of water.
  • the Adjusting devices 14 or the control valves 18 are controlled by a computing unit 15.
  • the strand guide rollers in these segments can be positioned in a wedge shape on the steel strand and thus enable a slight reduction in the thickness of the metal strand and an improvement in the metallurgical properties in the core zone of the steel strand.
