Iron sulfur powder

Use of sulfur iron powder: According to the use characteristics of steel, some steel needs to have a certain sulfur content. The traditional steelmaking production method is to artificially deteriorate the refining slag by sacrificing the good performance of strong deoxidation and purification of high-basic refining slag in the steelmaking process, and obtain better sulfur-increasing performance with sulfur iron powder, and then in the slag Sulfur alloy is added to increase the sulfur content in molten steel through the sulfur-increasing performance of the deteriorating refining slag at this time. The steel produced by this method has high oxygen content and many inclusions, which seriously affects the purity of the steel, but it can ensure the purity of the steel. The stability of the sulfur content in the


Since sulfur iron powder can significantly improve the machinability of steel, sulfur is usually added in the production of free-cutting steel such as ceramic dry steel, silicon steel and gear steel to improve the machinability of steel. The amount of sulfur added is 0, 08 ~ 0. 2%. In order to increase the sulfur content in steel, it is realized by adding sulfur iron powder in production. Sulfur iron powder is a method of pouring sulfur and molten iron into the ingot mould.
