Abstract： |
Preparing silumin and Al-Si-Mn-Fe-Ti alloy with coal ash of high-alumina powder, relates to the technical sphere of non-ferro metals smelting. The steps of the invented process are: 1) deironing from coal ash of high-alumina powder, and breaking separately the bauxite chamotte and reducer boghead coal and oil coke; 2) batching and mixing them; 3) adding adhesive and water to the mixture, globularzing and drying; 4) sending the dried pellet to the stove and smelting in a high temperature to prepare primary alloy; 5) cleaning up of inclusion and gas in the primary alloy by refining and filtering it; 6) adding manganese to the refined alloy and deironing and filtering to prepare the Al-Si-Mn-Fe-Ti allay; 7) adding Al to the deironed and filtered alloy, diluting and casting ingot, to prepare silumin. The invention is characterized in that the investment is a little, the productive cycle is short, the energy consumption is low, and the quality of the alloy is nice. |
