The core-filled continuous casting process is different from the CPC method and the double crystallizer continuous casting process. It is suitable for the case where the core metal has a low melting point and the outer layer metal has a high melting point. The above two methods are suitable for the high melting point of the core metal and the outer layer metal melting point. Low situation. Therefore, the CPC method and the double crystal continuous casting process are not suitable for the production of copper-aluminum bimetallic composite materials. Do you know what the double-flow casting method of copper-aluminum composite plate is like? Let me tell you about it below.
The dual-flow casting method is to add an inner ladle and its diversion system on the basis of traditional continuous casting. The inner and outer ladle respectively contain two melts with different compositions. The molten metal in the outer ladle flows through the water outlet and enters the crystallization. In the vessel, the molten metal in the inner ladle flows out of the inner duct and is surrounded by the solidified thin shell and residual external molten metal. By adjusting the process parameters during casting, the inner and outer molten metal can be controlled. The difference in the solidification time of the two liquids in the outer ladle promotes the sequential solidification of the melt in the crystallizer from the outside to the inside and realizes the partial mixing of the two liquids. The technical key and difficult point of this process is to control the flow rate and temperature of the two molten metals to form an intermediate bonding layer of appropriate thickness.
The core-filled continuous casting process is actually a kind of double-flow casting method. Core-filled continuous casting process (the upper and lower crucibles are used to melt the core metal and the outer layer of metal in the upper and lower crucibles respectively; the draft tube and the crystallizer together constitute the casting mold of the continuous casting pipe, and the outer layer of molten metal It solidifies to form a cast pipe: while pulling down the outer metal cast pipe, the core metal liquid is subsequently filled into the cast pipe. At a certain drawing speed and temperature, the solidification of the core metal and its interaction with the outer metal can be realized. Compounding, and then through the subsequent rolling process can obtain the composite sheet.
The above is about the double-flow casting method of copper-aluminum composite board, I hope it will be helpful to everyone.
