Description

Technical Field

[0001] The present application relates to the technical field of copper and aluminum product processing and production, and in particular to a smelting furnace guide tube. Background Art

[0002] Currently, after copper or aluminum waste is recycled, the waste is put into a smelting furnace for re-smelting.
