Suitable range: 0.07%-0.12%. Sulfur makes the length of graphite shorter, the end becomes blunt, the shape becomes curved, and the mechanical properties are improved in the range. Resulfurization is required when the sulphur content is less than 0.05%.

Metallographic analysis shows that sulfur of molten iron exists in a special form. Special Ferro sulphur must be used in resulfurization. sulphur or other sulphide mineral should not be used, otherwise the casting internal structure will be seriously damaged.

Usage of ferro sulphur:after a small amount of iron is added in the electric furnace during the production of electric furnace, the ferro sulphur with a particle size of 8-25mm is added to the furnace according to the demand of sulfur, the ferro sulphur is pressed by adding iron, and they are smelted. The absorption rate is above 99%.

Advantages of ferro sulphur: the high efficient ferro sulphur for casting gray iron produced by our company can be used conveniently, safely and reliably with few impurities and high absorption rate up to 95%. Sulfur can be added to gray pig iron for improving the cutting performance, and improving the inoculation effect and graphite shape. Because sulfur can make the length of graphite shorter, the end becomes blunt, the shape is curved, and the mechanical properties of the gray pig iron are improved by resulfurization. It is beneficial to control the sulfur in gray pig iron within the range of 0.08%-0.12%.
