Slag is also known as slag. The melt generated in the pyrometallurgical process floating on the surface of liquid substances such as metals is mainly composed of oxides (silica, alumina, calcium oxide, magnesium oxide), and often contains sulfides and entrained a small amount of metal.
According to the different metallurgical processes, slag can be divided into smelting slag, refining slag, synthetic slag; According to the nature of slag, there are alkaline slag, acid slag and neutral slag.
Slag composition: the formation of molten slag makes the gangue components or impurity oxidation products smoothly separated from the molten metal or molten metal;
Slag material: remove sulfur, phosphorus and oxygen in molten steel, absorb non-metallic inclusions in molten steel, and protect molten steel from direct absorption
Slag function: The slag role plays a decisive role in the smooth progress of smelting operations, smelting product quality, metal recovery rate and other aspects
