Definitions
- the invention relates to a method and a device for producing thin metal strands, in particular steel, in which a metal strip is passed through the bottom of a container filled with melt and, after the melt has been installed, is guided thereon via drivable rollers arranged above the container.
- This strip casting process is also called inversion casting because the solidification runs from the inside to the outside and not from the outside to the inside as is the case with conventional continuous casting.
- the diameter of the wire is non-uniform due to the bulge of the crystallized layer and is reworked for practical use. Furthermore, it is disadvantageous that due to the large thickness of the mother wire - 6 mm and larger are customary here - there is little crystallization and poor welding.
- the invention has set itself the goal of finding a method and a device, avoiding mechanical damage to the strip as it enters the melting vessel, preventing uncontrolled tensile stress conditions through increased friction (risk of tearing) and preventing the melt from flowing out of the container .
- the invention achieves this goal by the characterizing features of the method claim 1 and the Vor ⁇ chtu ⁇ gs claim 5.
- the molten bath in the region of the mouth of the slot-shaped inlet opening in the vessel is cooled so intensively that a temperature drop occurs here, which leads to a two-phase melt / crystal region slightly above the solidification point.
- This two-phase area which also comes into contact with the cold mother tape, has such a high viscosity that it takes on the function of a self-renewing seal and prevents penetration of the melt into the gap and the bottom passage.
- this melt which acts as a seal, is so large that the free space between the inner wall of the slit-shaped channel of the floor entry to the belt can be selected in a size that ensures a contact-free passage of the belt through the slit-shaped channel, not least through the training meniscus.
- copper can also be selected as material. To protect against abrasive wear, the copper can be provided with a protective layer. Metals (chrome, nickel) or oxides (zirconium oxide) or ceramics (e.g. boron nitride) are proposed as coatings.
- the cooling element is coated on the wall facing the vessel with a layer of a refractory mass. In this way, not only is a higher protection of the cooling element achieved, this measure also has an influence on the temperature level of the colder melt in the vicinity of the cooling elements, which is comparable to a bed.
- the slot-shaped channel can be designed in a low-maintenance and inexpensive manner in such a way that it is constructed from two parts.
- One part consists of copper, as described, and the part pointing away from the melt is made up of a refractory mass or refractory stones.
- the inventors propose to provide the cooling element with a cone that opens towards the inside of the vessel.
- cooling medium is proposed as the cooling medium, but also gas.
- water When water is used, it is sucked to prevent damage to the cooling elements if damage cannot be ruled out.
- cooling tubes are used which are meandering.
- the tube coil used is designed in such a way that the coolant is first guided in the vicinity of the slot.
- the heat dissipation from the molten metal in the area of the mouth of the channel is regulated depending on the temperature of the molten bath. If the melt cools down too much, it can be set to the desired temperature by means of a heating device, for example a plasma torch.
- Figure 1 shows a schematic section through the casting device
- Figure 2 The arrangement of the cooling coil.
- Figure 3 section of the bottom opening.
- Figure 1 shows a melting vessel with the vessel bottom 1 1
- Vessel side walls 12 which have a metallic vessel jacket 13 and a refractory lining 14.
- the bottom has a channel 20.
- the mouth of which faces the melt S has a metallic channel part 22, here designed as a cooling box 25
- the cooling box 25 is connected to a pump 33 via a media supply 31 and a container 34 or via a media discharge 32
- a band B is guided through the channel 20 by guide rollers 41 to the melt S in the container.
- a layer K crystallizes on band B. which is required above the vessel by smoothing rollers 42 and smoothed close to the final dimensions.
- a device 51 for measuring and regulating the thermal energy is connected to the media outlet 32
- FIG. 2 shows horizontal sections through the metallic channel part 22, which is designed here as a cooling tube 26, which is connected to the inlet 31 and the outlet 32.
- a cooling tube 26 which is connected to the inlet 31 and the outlet 32.
- the strip B is guided through the slot 20
- FIG. 2 shows horizontal sections through the metallic channel part 22, which is designed here as a cooling tube 26, which is connected to the inlet 31 and the outlet 32.
- the strip B is guided through the slot 20
- FIG. 2 shows horizontal sections through the metallic channel part 22, which is designed here as a cooling tube 26, which is connected to the inlet 31 and the outlet 32.
- the strip B In the center of the meandering cooling tubes 26, the strip B is guided through the slot 20
- the arrows indicate the flow direction of the cooling medium. It can be seen that the cooling medium is first led around the belt and then parallel to the coil in the area of the
- tubes with a circular profile can be used, as can square tubes.
- FIG. 3 shows a section of the vessel with the metallic vessel jacket 13 and the refractory lining 14, in the right part as a ramming compound and in the left part as a stone.
- the channel 20 has an elevation, which is inclined towards the metallic vessel jacket 13 on a refractory channel part 21, in the left half of the picture as a refractory stone 23 and in the right half as a refractory ramming compound 24.
- a molten metal channel part 22 is inclined towards the melt and is designed as a cooling tube 26 in the left half of the figure and as a cooling box 25 in the right half of the figure. In the direction
- this channel part 22 is covered with a refractory layer 15.
- the channel 20 has an inner channel thickness D through which the tape B with the tape thickness d is passed.
- melt S isotherms of the melt S are shown in FIG. 3. It can be seen that there is one in the slot-shaped channel in the area of the metallic channel part 22 Temperature sink near the solidification point TSOL. This two-phase melt / crystal area prevents the melt from leaking out of the melting vessel through the slot-shaped channel.
- melt S itself has not yet solidified but is still ductile but firm enough to prevent the melt from escaping from the channel.
