Aluminum and aluminum alloys can be used a variety of methods smelting. Often using a coreless induction furnace and trough induction furnace, crucible furnace and open hearth furnace reflective (use natural gas or fuel oil combustion) and resistance furnaces and electric radiant. Charge a wide range, from high-quality pre-alloyed ingot until special charge constituted by the low-level waste can be used. However, even under the most suitable conditions for melting and pouring of molten aluminum also vulnerable to the adverse effects of three types: · at high temperature, the alloy scrap recycling, with the passage of time, waste alloy, adsorption of hydrogen dissolved in the cause increase the melt of hydrogen. ? In high temperature conditions, as time goes on to ask, melt oxidation. · Loss of alloying elements. Aluminum smelting products and pressure processed sub-types of the torch, the former chemical composition Al, said the latter represented by Pinyin LV (aluminum, industrial use). Aluminum alloy by deformation processing methods can be divided into aluminum and cast aluminum two categories: the deformation of aluminum can withstand the pressure processing. Processed into various forms, specifications of aluminum material. Mainly for the manufacture of aviation equipment, building doors and windows. Deformation is divided into non-heat strengthened aluminum alloy and heat treatment strengthened aluminum alloy. Enhanced heat treatment can not by heat treatment to improve mechanical properties, can only be achieved by cold deformation strengthening, which includes high purity aluminum, industrial high purity aluminum, industrial aluminum and rust-proof aluminum. Heat treatable aluminum alloy can be used to improve the mechanical properties by quenching and aging heat treatment, it can be divided into hard aluminum, wrought aluminum, super-hard aluminum and special aluminum alloy. _ Shengxin buy scrap metal scrap metal recycling (Online) _ scrap metal recycling scrap metal from the Linyi City Shengxin Limited.
