Sulfur cored wire is processed by wrapping sulfur powder with steel belt.

① It is beneficial to adjust and control the sulfur content in liquid steel or molten iron, and steel products or iron products with appropriate sulfur content can be obtained.

② Sulfur is added into molten steel to produce sulfur-containing free cutting steel, and the recovery rate of sulfur can reach more than 80%.

③ Adding sulfur into stainless steel molten steel is conducive to improve the cutting performance of steel products and change the morphology of sulfide inclusions.
