Place not long, relatively clean surface of aluminum ingots and metal type return charge may not be processed by the blow, but it should be mixed in the charge to eliminate iron filters and mosaic pieces, stainless steel recycling, all of the charge in the blast furnace It should be preheated to remove moisture attached to the surface, to shorten the melting time of 3 hours or more. 2, charge management and rational conservation and management of storage charge of alloy to ensure quality is important. Charge should be stored in the temperature changes little, dry warehouse.
