Silicon-manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. Silicon-manganese alloy is a composite deoxidizer commonly used in steelmaking, and it is also a reducing agent for low-carbon ferromanganese and electro-silicon thermal production of metal manganese in production. Silicon-manganese alloys can be smelted by continuous operation in large, medium and small submerged arc furnaces.

Silicon calcium alloy is an ideal composite deoxidizer and desulfurizer. Silicon calcium alloy is widely used in the production of high-quality steel, low-carbon steel, stainless steel and other steel grades and special alloys such as nickel-based alloys and titanium-based alloys; it is also suitable as a warming agent for converter steel refining workshops; Silicon calcium alloy can also be used as an inoculant for cast iron. and additives in the production of ductile iron. Since about 1907, silicon-calcium alloys have been produced by the electrosilicothermic method.

High-carbon ferrosilicon is a commonly used deoxidizer with the following advantages: no hydrogen source is generated during the deoxidation process, ensuring safety and reliability; carbon and silicon are important elements that determine the function of steel, and high-carbon ferrosilicon can not only react with oxygen in molten steel. To the deoxidation effect, the remaining carbon and silicon that have not been oxidized can also be dissolved in the molten steel to increase silicon and carbon, and achieve the effect of killing two birds with one stone.

the fluidity of this refining agent is very good, the kinetic conditions of the desulfurization reaction are optimized, and deep desulfurization can be realized.

Steelmaking carburizer: with the development of new smelting process mature, in the smelting process, due to improper ingredients or charging and excessive decarburization and other reasons, sometimes resulting in steel carbon content did not reach the requirements of the top period, prompting producers to carburization in liquid steel.

Ferro silicon lumps: no matter what smelting process is used to make steel, deoxidation alloying is needed. Because of the different smelting process conditions, the oxygen content and inclusion content of steel are not the same. According to the different requirements of the quality of steel, the deoxidizer commonly used in steelmaking production is ferromanganese, ferro silicon lumps,
