Problems solved by technology

The heater is required to be powered on continuously, even if the power is not cut off during the production gap, so as to keep the alloy liquid in the melting channel, so the power consumption is large; the cold start method is adopted, and the first batch of alloy liquid injected into the insulation bag must have a cooling process , the fluidity of the alloy liquid is reduced, and a large amount of electric energy must be consumed to increase the temperature of the alloy liquid in the heat preservation bag, which reduces the productivity. When pouring out the alloy liquid in the heat preservation bag, the heat preservation bag needs to be tilted over 90 degrees, which is inconvenient to operate; When changing the alloy type, it is not easy to clean the inner chamber and the melting channel. On the one hand, it is easy to cause mixed materials, which will reduce the quality of the drawn and cast bars; on the other hand, it is not suitable for small batch and multi-variety production; High-quality refractory materials have poor thermal insulation and increase energy consumption. The crystallizer in the horizontal continuous casting device introduced in "Nonferrous Metal Melting and Ingot Casting" is for one-time use, which increases production costs.
