This equipment is designed as a special equipment for aluminum alloy edge insulation and aluminum zinc liquid conveying in centralized melting furnace. It adopts imported high-grade refractory ceramic materials with low heat transfer and non-stick aluminum. Made with 6mm thick steel plate. The heat loss and heat radiation area of the main surface of the flow channel are minimized, which effectively saves energy and improves the high temperature working environment. At the same time, the aluminum liquid does not directly contact with the air, reduces the surface oxidation of the aluminum liquid, reduces the liquid to gas, and can effectively control and stabilize the quality of the aluminum soup.
