1, charge handling charge before use should be treated by blowing sand to remove surface rust, grease and dirt. Qingdao expensive place not long aluminum recycling, surface cleaner aluminum ingots and metal type return charge may be used without blowing sand Qingdao high aluminum recovery, but it should be mixed in the charge to eliminate iron filters and inserts, etc. Qingdao High aluminum recovery, all the charge in the blast furnace should be preheated to remove moisture attached to the surface of Qingdao high recovery of aluminum, 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. Aluminum and aluminum alloy aluminum profiles 1. The main products obtained by extrusion, the resulting product may be a plate, a rod and a variety of profiled sections, it can be widely used in construction, transportation, aerospace and other fields of new materials. Aluminum alloy sheet according to the non-painted surface treatment can be divided into two major categories of products and paint products. (1) can be divided into aluminum hammer (irregular pattern), embossing plate (regular patterns) and pre-passivated, anodized aluminum surface processing board. (2) This item is not painted on the plate surface treatment, the surface appearance of the less demanding lower prices. 2) paint products (1) Category: Press the coating process can be divided into: Spray board products and pre-roll coating plate; can be divided according to the type of paint: polyester, polyurethane, polyamide, modified silicone, epoxy resins, fluorocarbon and the like. (2) a variety of coatings, the main performance difference is resistance to ultraviolet sunlight, which in front of the most commonly used coating is fluorocarbon (PVDF), a strong resistance to UV its capacity; the back of the optional polyester or epoxy resin as a protective lacquer coating. Also front protective film can be attached tear-away. Aluminum recycling company, Weihai aluminum recycling, Shengxin recycling scrap metal recycling scrap metal from the Linyi City Shengxin Limited.
