There are many problems in the recovery of copper chips directly into the furnace, the recycling of copper brass chips reduces the production cost of foundry enterprises and greatly improves the market competitiveness of the enterprises. The copper scraps are small, loose, directly into the furnace will be seriously blocked, the material block clearance is the furnace gas rising channel, directly affect the smelting process, the loose steel scrap without pressing, extremely easy to float on the furnace lining, corrosion lining, and large loss of raw materials will cause low molten iron rate.
