Definitions
- the invention relates to a method and a device for continuous Casting steel strip, especially in the thickness range between about 1.0 mm and 6.0 mm of molten steel that is in contact with a movable surface area of the coolable jacket of a casting roll, at least partially Formation of a strand shell solidifies and thereby in the gap between the jacket the casting roll and at least one counter roll a first profile of the belt is preformed.
- the device for this comprises a molten pool of aluminum in contact with the surface of an inclined, upwardly movable cooled support for pulling metal out of the Weld pool.
- the carrier is either an endless belt or a drum.
- Creusot-Loire Another method of the company mentioned in the publication mentioned Creusot-Loire provides that molten steel flows into an upstream river Gap between two cooled cylinders under a pressure frame as required of the hydrostatic pressure of the molten metal is injected and the so produced cast tape first along the periphery of one of the cylinders is carried out until it is completely frozen.
- the object of the invention based, a much improved process for the continuous casting of Band, especially in the thickness range between about 1.0 mm and 6.0 mm Melting steel to indicate which is a particularly economical manufacture of steel strip in a uniform thickness and with a structurally uncomplicated Device is feasible.
- the invention proposes a method of the type characterized in the preamble of claim 1 in accordance with the characterizing features of claim 1, according to which molten steel flows out of a distributor at a speed V s in accordance with its ferrostatic height H, and this by contact with the surface area of the roller, partially pre-shaped strip is re-formed when passing through at least one of the post-forming gaps, one behind the other in the casting direction, between the shell of the roller and the counter-roller, and in particular thereby reduced thickness when solidified.
- the method according to the invention enables manufacture with great advantage of steel strip by continuous casting in the thickness range between approximately 1.0 mm and 6 mm directly from the molten steel, reducing production costs for steel strip compared to the production from thicker slabs by means of multi-stage Thickness reduction by rolling mills can be significantly reduced. About that Furthermore, due to the avoidance of segregations, a faultless, high-quality Product achieved.
- a preferred embodiment of the method provides that the peripheral speed the coolable roller of the exit velocity of the melt the distributor is adapted.
- an embodiment of the method provides that the ferrostatic height H of the melt in the distributor continuously measured and by regulating the Inflow of melt from a ladle through an intermediate container (Tundish) in the distributor is kept constant. This is particularly because of this achieved that to introduce melt from the ladle over the tundish an immersion tube is used in the distributor.
- An arrangement has an essential effect on the quality of the cast steel strip the method characterized in that the outflow area of the melt the distributor by feeding inert gas against the entry of atmospheric oxygen is shielded. Reoxidation of the melt in the intermediate distributor (tundish) and distributor is avoided by slag. The inert gas atmosphere is preferred up to a subsequent rolling mill.
- An embodiment of the method essential to the invention provides that the roller and / or counter roll (s) and guide rollers by means of cooling bores or cooling grooves be intensively cooled at least inside.
- the casting roller can also be sprayed from the outside using water spray is cooled and / or cleaned.
- means are provided for Supplying inert gas to the outflow area of the melt,
- the coolable casting roll and counter roll (s) consist of a CuNiBe alloy.
- the device provides that the guide rollers with comparatively small diameter can be formed from solid material. These exist preferably made of a CuNiBe alloy, which is in contact with liquid steel has proven to be particularly temperature and wear resistant.
- Another advantageous embodiment of the device provides that several Counter rolls are combined in one segment to form a guide unit and can be interacted with adjusting means.
- the casting roller, the counter roller and the guide rollers can at least some with leading edges corresponding to the thickness of the cast product Be formed height, or be concave if the steel strip a certain profile increase of z. B. 1% of the strip thickness.
- FIG. 1 schematically shows a preferred embodiment both the process for casting steel strip and the most suitable one Design of a device intended for this purpose.
- the device has a ladle 4 containing molten steel 10 with a pouring tube 11 '.
- a controllable throttle element 11 ′′ is installed in the upper region of the pouring tube 11 ′, which is controlled by a level indicator 17, for example an electronic sensor, in cooperation with an actuator 17 ′.
- the actuator is also in a regulating connection a drain plug 17 ", which opens further, for example, when the melt level rises, and on the one hand opens the throttle member 11" further when the melt level falls, and occasionally closes the drain plug.
- the level F of the melt in the distributor 3 is also taken into account and strictly From the intermediate distributor 31 (tundish), at a speed V s melt resulting from the constant ferrostatic melt height, melt flows from the distributor 3 through the pouring opening 5 onto the rotatingly moving surface of the coolable casting roller 1 in a controllable thickness of between approximately 0 to 6.0 mm and is conveyed further at an angle ⁇ at the speed V w on the path 13 ', spontaneously in contact with the cooled surface of the jacket 13 of the roller 1 to form a solidifying belt 20 in the direction of the rotating surface is transported further.
- the reduction in thickness in the first mold gap 22 can be between 5% and 20% of the Casting thickness, and set in the second post-forming gap 22 'between 10 and 50% become.
- the coolable casting roller 1 should preferably consist of a CuNiBe alloy. This alloy has been used in the construction due to the good thermal conductivity and wear resistance well proven.
- the casting roller 1 is internally cooled via cooling bores or cooling grooves.
- the guide rollers 7, 7 'can have a comparatively small diameter and Advantage be made of solid material. They preferably also exist made of a CuNiBe alloy. However, they can also have a steel jacket and be chilled inside.
