[0002] In actual metal processing work, such as the processing and manufacturing of copper strips, copper alloys need to be heated and melted in a smelting furnace, and then the molten liquid is transported and then formed into copper strips. The molten copper is transported to a holding furnace for insulation. If the liquid level in the holding furnace is too low, it is easy to cause traction to fail to keep up. If the liquid level in the holding furnace is too high, the molten copper is easy to overflow.
