Aluminum chloride melting furnace usually refers to a high-temperature equipment used in the process of manufacturing or processing aluminum chloride, mainly used to generate aluminum chloride through the reaction of aluminum and chlorine. In this process, a melting furnace may be needed to maintain a certain temperature so that the aluminum raw material can fully contact with chlorine and react chemically to generate aluminum chloride. The existing aluminum chloride melting furnace has a fixed auxiliary stirring and melting mechanism, which results in a longer melting reaction time.
