Definitions
- the invention relates to a method for uniformizing a molten metal film, in particular a steel film, in accordance with the preamble of the first claim and a device for carrying out the method.
- the invention can be used wherever a molten metal film, in particular made of steel, is applied to a substrate, in particular to a rotating conveyor belt, in the form of a melt and should have the same thickness and properties as possible across the width of the belt.
- the casting thickness of the strip can be chosen largely optimally in accordance with the required thickness during finish rolling and with the required hot forming to achieve sufficient material properties. It is known to cool the molten metal by appropriate methods and devices so that the strand surface of the liquid metal strand is evenly cooled by contact with an inert gas.
- DE 44 07 873 C2 describes a method and a device for cooling molten steel, in which nozzles are directed at an angle between 0 and 50 ° in the casting direction onto the surface of the steel strand, as a result of which the steel surface is cooled uniformly and in a targeted manner. In this way, any scaling can be avoided and a targeted heat dissipation can be achieved, whereby the surface tension is influenced in a targeted manner and the desired quality of the steel strand or the steel strip is achieved. What is important for the quality of a steel band is its constant thickness in connection with constant material properties across the width of the band, what - 2 -
- the solution according to the invention provides that forces are applied across the width of the casting belt to even out the applied metal film, which forces the molten metal to be even.
- gases are inert gases, such as argon or nitrogen, optionally with admixing reducing components, for example H 2 , CO, or oxidizing components which influence the surface tension, such as 0 2 , C0 2 .
- gas nozzles side by side and one behind the other in such a way that they have the shape of a rake. It is thereby achieved that the liquid metal film which is transported against the outflow direction of the gas is treated by the emerging gas jets as with a rake, which leads to a braking and equalization of the melt across the width of the strip.
- Two or more rakes arranged one behind the other in the mode of action of a Pascal triangle are particularly advantageous, offset in each case. As a result, the strip is largely the same thickness over its width and the material properties are made more uniform over the same.
- the nozzles are at an angle such that the gas stream strikes the surface of the melt film at an angle between 10 and 80 ° to the vertical, counter to the direction of flow of the cast strip.
- a solidification-initiating agent to the metal film in order to achieve an advantageous solidification of the surface.
- an oxidizing gas containing CO 2 is used as the solidification-initiating agent, which means that a thin surface layer of the melt film decarburises and the solidification temperature can thus be raised above the actual temperature to such an extent that the solidification starts from the top.
- the C0 2 content must be kept so low that there is no slag formation.
- a cooling and nucleating powder for example metal powder, a liquid slag, a gas or another liquid metal can also be used as the solidification-initiating agent.
- Figures 1 and 2 show the situation with flow modifications.
- the gas jets 7 emerge from gas nozzles 3 with 1 mm diameter bores in two rows at staggered positions from a copper profile 6 containing two chambers, one of which is used for gas supply and one for water cooling of the copper profile 6. These gas jets 7 impinge on the melt flowing onto the conveyor belt 2 at an angle of 30 ° to the vertical of the surface against the pouring direction and slow them down.
- the flow cross-section increases to the target size.
- a compensation of the melt in the transverse direction can take place in the pent-up melt between the application point and the impact area of the gas in order to achieve a uniform thickness profile.
- Gas flow in the form described can be compared overall with that of a rake to achieve an even material distribution ("Pascal's Argon rake").
- a corresponding argon rake can be used to ensure an even material distribution at the feed level.
