Intrusive heating melting pool aluminum liquid insulation furnace is mainly used for aluminum liquid insulation in the process of metal die casting,gravity casting or low-pressure casting,and immersion heating melting pool insulation furnace uses ceramic heaters to immerse aluminum liquid to directly heat the aluminum liquid in the melting pool. It has the following advantages:high heat transfer efficiency,fast heating speed of aluminum liquid.less inhalation of aluminum liquid,uniform temperature of aluminum liquid,and less oxidation of aluminum liquid.
