Iron sulfide 80# (2)

Smelting additive agent of ferro sulphur and ferrous sulphide ferro sulphur- special steel (free-machining steel) for foundry industry.Ferro sulphur is generally used for increasing the sulfur content of gray pig iron or molten iron, too low sulfur in gray pig iron is harmful: poor inoculation effect, poor graphite shape and poor cutting performance.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%.In addition, our company is specialized in the production of ‘Hengkai Metallurgical" Brand - ferro sulphur series for foundry, copper removal agent series for lead smelting, debismuthizing agent for lead smelting, iron sulphide series for resin grinding wheel abrasive industry, iron sulphide series for brake pad friction industry,and so on.
