Founded in 1988, Wuxi Yongxin Special Metals Co., Ltd. is a professional manufacturer of nodularizing agents, inoculants and alloy cored wires. The company is headquartered in Wuxi City, Jiangsu Province, and has two production bases in Xuzhou City, Jiangsu Province and Ya'an City, Sichuan Province, covering a total area of about 65,000 square meters and a construction area of about 25,000 square meters. The company's main products are spheroidizing agent, inoculant, vermicularizing agent, cored wire and related casting materials.

1 Definition The inoculant is a kind of inoculant that can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic groups, and refine the matrix structure. good effect. It is mainly suitable for general occurrence or late instantaneous inoculation in various situations. 2 How to use 1. Inoculation by pouring the bag: Add the inoculant into the bag, and then pour it into the molten iron to make it melt evenly, and then pour it. 2. The added amount is about 1.0-1.8% by weight of molten iron.

The role of inoculants in ferroalloys Ferroalloys are generally used as: ① Deoxidizer. In the steelmaking process, oxygen is removed from molten steel, and some iron alloys can also remove other impurities in steel such as sulfur and nitrogen. ② Alloy additives. According to the composition requirements of the steel grade, alloying elements are added to the steel to improve the properties of the steel. ③ Inoculant. It is added into molten iron before casting of cast iron to improve the crystallographic structure of the casting. In addition, it is also used as a reducing agent for the production of other ferrous alloys and non-ferrous metals by metallothermic reduction; an alloy additive for non-ferrous alloys; and a small amount is also used in the chemical industry and other industries. The use of inoculants is more and more widely used in ferroalloys, and the price of inoculants is also adjusted accordingly in the market with the use of ferroalloys.
