Description
Technical field
The present invention relates to a kind of slag charge of removal impurity of metallic substance technical field, specifically is a kind of slag charge that is used for removing the aluminium alloy element silicon.
Background technology
Because therefore series of advantages such as aluminium alloy has that density is little, specific tenacity is high, solidity to corrosion and good moldability, cost are low are widely used in industries such as communications and transportation, electronics, bridge, decoration, the purposes consumption occupies the hat of nonferrous materials.And the continuous expansion of using along with aluminium alloy is more and more higher to the requirement of its purity.Silicon is main impurity element in most of wrought aluminium alloies, mainly introduce by the starting material (primary aluminum etc.) of preparation wrought aluminium alloy, in addition, in the aluminium alloy smelting process with the pollution that also can cause silicon that contacts of refractory materials.And these are incorporated into element silicon normal and impurity iron element and the generation of other alloying elements AlFeMnSi, Mg in the wrought aluminium alloy system
