Definitions
- the invention relates to a method and an apparatus for producing thin Strands of metal, especially steel, in which a metal band through the bottom of a container filled with melt passed and after crystallization of the melt this is guided over drivable rollers arranged above the container.
- This strip casting process is because the solidification runs from the inside out and not like in the usual continuous casting from the outside in, also inversion casting called.
- WO-A-87 07 192 is a device for producing thin metal strands a vessel with a refractory lining is known, in the bottom of which a is provided for introducing a metal strip opening, this as slot-shaped channel is formed. To increase the overall thickness of the tape obtained, it can be pulled through the melt in several cycles.
- Another device for producing thin metal strands is from DE-A-36 38 249 known. Here is between the channel wall and the tape to be coated certain distance maintained.
- a method is known from US Pat. No. 4,479,530, but wire - here from above down - to pass through a melt and through the bottom outlet of a Lead melting vessel. Designed for the production of copper wire Process is proposed not only to design the floor outlet conically, but to let the melt escape together with the wire.
- the aim of the invention is to find a method and a device mechanical damage to the strip when it enters the melting vessel to avoid uncontrolled tension conditions due to increased friction (Risk of tearing) and to prevent the melt from flowing out of the container prevent.
- the melt pool is in the area of the mouth of the slit-shaped Inlet in the vessel cooled so intensely that there was a drop in temperature ententent to a two-phase melt / crystal area slightly above the Freezing point leads.
- copper can also be selected as the material.
- the copper can be provided with a protective layer.
- metals chrome, nickel
- oxides zirconium oxide
- ceramics e.g. boron nitride
- the cooling element on the to the vessel indicative wall covered with a layer of a refractory mass.
- the slot-shaped channel can be low-maintenance and inexpensive be designed so that it is composed of two parts.
- the inventors propose the cooling element to be provided with a cone opening towards the inside of the vessel.
- a liquid is proposed as the cooling medium, but also gas.
- This water is sucked up, so that it cannot be excluded Damage to the cooling elements to avoid damage.
- cooling tubes are used which are meandering are led.
- the coil used is designed in such a way that Coolant is first routed near the slot.
- the heat dissipation from the molten metal in the area of the mouth of the channel is in Regulated depending on the melting bath temperature. If the This can melt through a heating device, for example through a Plasma torch can be set to the desired temperature.
- FIG. 1 shows a melting vessel with the vessel bottom 11 and the Vessel side walls 12, the metallic vessel jacket 13 and a refractory Have liner 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 cooler 25.
- the cooling box 25 is via a media feed 31 and a container 34 or a media discharge 32 is connected to a pump 33.
- a band B is guided through the channel 20 by guide rollers 41 to the melt S in passed the container.
- a layer K crystallizes on band B, which lies above the Vessel is promoted by smoothing rollers 42 and smoothed close to the final dimensions.
- a device 51 for measuring and controlling the Thermal energy connected.
- FIG. 2 shows horizontal sections through the metallic channel part 22, which is shown here as Cooling tube 26 is formed, which on the feed 31 and the discharge 32nd connected. This is in the center of the meandering cooling tubes 26 Band B passed through the slot 20.
- tubes with a circular profile can be used come, as well as 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 ramming mass and in 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, specifically in the left half of the picture as a refractory stone 23 and in the right picture as a refractory ramming compound 24.
- a metallic channel part 22 is inclined towards the melt, which 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 of the interior of the vessel, this channel part 22 is covered with a refractory layer 15.
- the channel 20 has an inner channel thickness D through which the band B with the Band thickness d is guided.
- melt temperature T SOL isotherms are shown up to the melt temperature T SOL .
- a meniscus M is formed between the belt B and the cooling box 25 under the cooling tube 26.
- the shape of the meniscus is formed, with the conical end face projecting deeper into the slot-shaped channel 20.
- the melt S itself has not yet solidified but is still ductile but firm enough to prevent the melt from escaping from the channel.
