[0004] In the above-mentioned prior art, although the liquid in the crucible in the electric heating smelting furnace can be poured out by controlling the tilt of the crucible through a motor, which is relatively convenient, there is a lack of corresponding flue gas treatment measures. Under high temperature, metals such as copper react with oxygen to produce a large amount of oxides, part of which volatilizes into flue gas. The electric heating furnace uses a variety of auxiliary materials, such as coating materials, heat stabilizers, reducing agents, etc. These auxiliary materials will also decompose at high temperatures to produce gases, further increasing the amount of flue gas generated. These flue gases generated at high temperatures contain more harmful substances, which will cause harm to the environment and human health. Therefore, an electric heating smelting furnace is now proposed. Utility Model Content
