Background
The micro-alloyed copper alloy has excellent comprehensive properties of mechanical property, electric conduction, heat conduction, corrosion resistance, fatigue resistance and the like, and is widely applied to electric wires and cables, IC lead frame materials, electrified railway contact wires and other fields requiring the electric conduction and heat conduction properties of the alloy. These alloy elements are easy to oxidize and refractory during smelting, such as CuFe, cuCr, cuTi, cuCrZr and other series alloy, and are ideal high strength high conductivity copper alloy material, but Ti, cr, zr and other elements are difficult to melt and easy to oxidize.
Because the common problem of the alloy is that the alloy elements have very high activity, and react with a plurality of elements at the smelting temperature to cause burning loss, the melt is easy to oxidize, slag and suck. The difficulty is very high and the process is very unstable for preparing the alloy with qualified components.
At present, in addition to gas furnaces, industrial copper and alloy smelting mainly adopts a cored power frequency induction furnace in the aspect of electric furnaces, and the furnace type adopts a tilting type or submerged type to connect the smelting furnace with a casting furnace, so that the casting furnace can be ensured to always have enough copper liquid, and continuous ingot casting production can be realized. The cored power frequency induction furnace heats the metal melt at the melting channel and then conducts the metal heat at the melting channel to the melt above, so that the temperature at other parts is lower in spite of the higher temperature at the melting channel, and the temperature is difficult to reach more than 1200 ℃. Therefore, when preparing some copper alloys containing alloy elements with higher melting points, the temperature requirement of the cored power frequency induction furnace is difficult to ensure. Such as CuFe, cuCr, cuTi, cuCrZr, are not suitable for production by using a cored power frequency induction furnace.
Therefore, the coreless medium frequency induction furnace is adopted for smelting the alloy at present. The induction magnetic field of the coreless medium-frequency induction furnace penetrates into all corners, and electromagnetic stirring is smooth, so that the heating temperature is uniform, the heating speed is high, and the requirements of smelting and casting temperatures are met. However, the coreless intermediate frequency induction furnace cannot perform submerged flow arrangement of two coreless furnaces due to the problem of coil arrangement, and it is difficult to install a crystallizer for horizontal continuous casting, but continuous up-casting and down-casting cannot be performed in a tilting type combination. Therefore, the continuous production can only be realized by furnace at present, the single weight of the product is limited, and the yield is low.
