Black silicon carbide is made from quartz sand and petroleum coke silica as main raw materials through high-temperature smelting in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made from petroleum coke and silica as the main raw materials, with salt added as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum.

Ferromolybdenum is an alloy of molybdenum and iron and is mainly used as a molybdenum additive in steelmaking. Adding molybdenum to steel can make the steel have a uniform fine-grained structure, which can help remove temper brittleness and improve the hardenability of the steel. In high-speed steel, molybdenum can replace part of tungsten. Along with other alloying elements, molybdenum is widely used in the production of heat-resistant steels, stainless steels, acid-resistant steels and tool steels, as well as alloys with special physical properties. Adding molybdenum to cast iron can increase its strength and wear resistance. Ferromolybdenum is usually smelted by metal thermal method.

Titanium is one of the lighter and extremely hard metals discovered so far, while stainless steel is an iron-carbon alloy. Moreover, titanium alloy is much better than stainless steel in terms of performance. It is light in weight and high in hardness. Its oxidation resistance (that is, rust) is similar to that of stainless steel, but the price is correspondingly much more expensive.

Metal silicon 200 mesh is silver gray with metallic luster. It has a high melting point, good heat resistance, high resistivity and high oxidation resistance.

Since calcium has a strong affinity with oxygen, sulfur, hydrogen, nitrogen and carbon in molten steel, calcium silicon alloy is mainly used for deoxidation, degassing and fixation of sulfur in molten steel. Calcium silicon produces a strong exothermic effect when added to molten steel.

The ferrosilicon granule inoculant is formed by breaking ferrosilicon into small pieces of a certain proportion and filtering them through a sieve with a certain mesh size.
