Smelting furnace for producing antioxidant alloy tin solder

The utility model belongs to the technical field of smelting furnaces, and particularly relates to a smelting furnace for producing antioxidant alloy tin solder, which comprises a furnace body, a heating pipe is wound on the furnace body, a mixing mechanism and a turnover mechanism are mounted on the furnace body, the mixing mechanism is in transmission connection with the turnover mechanism, and the turnover mechanism is in transmission connection with the heating pipe. The utility model has the beneficial effects that by arranging the turnover mechanism, the materials at the bottom of the furnace body can be turned over up and down, and the materials with high density in the furnace body are prevented from sinking to the bottom, so that the materials can be mixed more uniformly, and the quality of the welding flux prepared in the later period can be improved; the protective heat preservation shell is arranged to wrap and protect the furnace body, so that the heating pipe and the furnace body are prevented f
