Silicon Carbide Introduction

Silicon carbide deoxidizer can improve steel strength and toughness, it quickly deoxidize, greatly reduce smelting cost, stabilize the quality of molten iron, and delay the hatching and reduction time of molten iron.

Silicon carbide deoxidizer can replace the more expensive traditional deoxidizer ferrosilicon powder and alloy powder. It is suitable for deoxidation during smelting of general steel, alloy steel and special steel. With the advantage of rich foam, it can also effectively improve recovery rate.  The use of silicon carbide as a steelmaking deoxidizer can stabilize the quality of molten steel, and has the effect of refining the particles of molten steel and removing harmful impurities. After use, the casting temperature of molten steel is high and the quality of casting slabs is excellent.

Features of Silicon Carbide

  • Compared with ferrosilicon powder, carbon powder and calcium carbide, silicon carbide's oxygen reaction can shorten the reduction time, reduce power consumption and improve labor productivity.
  • The decomposition and oxidation of silicon carbide deoxidizer at high temperature is an exothermic reaction process, and the positive pressure in the furnace is strong, which can ensure the necessary conditions for deoxidation and sulfur removal and reduce the sulfur content.
  • By shortening the reduction period, the probability of sucking molten metal at the rear is lowered and the quality of molten metal is secured.
  • Reduce the amount of quicklime and fluorite powder added, reduce cost, reduce harmful gas concentration and dust pollution, help improve working conditions.
  • The foam slag is rich and active, and at the same time, the bubble wraps the arc yellow to reduce the arc radiation, thereby improving the life of the furnace lining and the furnace cover, reducing the heat shutdown time and the consumption of auxiliary materials.

Ferro Silicon

FeSi 72, Fesi 75 Ferro Silicon

Ferrosilicon is made from coke, steel shavings, and quartz (or silica) and is smelted in an arc furnace. Ferrosilicon is widely used as a deoxidizer in the steelmaking process, and at the same time, since the amount of heat released when SiO2 is formed is large, it is also advantageous to increase the temperature of molten steel during deoxidation. Ferrosilicon is widely used in low-alloy structural steel, bond steel, spring steel, bearing steel, heat-resistant steel, electrical silicon steel, etc., and is often used as a reducing agent in ferroalloy production and chemical industry.
Application: Ferrosilicon is widely used in steel industry, foundry industry and other industrial production.

Ferro Silicon Application

  • Ferrosilicon is an important oxygen scavenger in the steel industry. In steel manufacturing, ferrosilicon is used for precipitation and diffusion deoxidation. Adding a certain amount of silicon to steel can greatly increase the strength, hardness and elasticity of steel, increase the magnetic permeability of steel, and reduce hysteresis loss of transformer steel.
  • The chemical affinity between silicon and oxygen is very high, and the carbon content of ferrosilicon is very low. Therefore, high-silicon ferrosilicon is a commonly used reducing agent for the production of low-carbon ferroalloys in the ferroalloy industry.
  • Ferrosilicon is used as a reducing agent in the production of low carbon ferroalloys in the ferroalloy industry. The addition of ferrosilicon to cast iron can be used as an inoculum for ductile iron, prevent carbide formation, promote graphite precipitation and spheroidization, and improve the performance of cast iron.
  • It is used as an inoculant and nodularizing agent in the cast iron industry. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron and promote the precipitation and nodularization of graphite, so ferrosilicon is an important inoculant and nodularizing agent in soft iron production.

JBT supplies metallurgical silicon metal 553, 551, 511, 441, 421, 411,  3303, 2202, 1101 and silicon metal 97.
In the aluminum industry, silicon metal is used as a reducing agent to remove impurities from aluminum alloys, and it is also used as an alloying agent in the production of aluminum alloys. In the steel industry, silicon metal is used as a deoxidizing agent to remove oxygen from steel and to improve its mechanical properties.
Silicon metal is added to aluminum alloys as an alloying agent to improve their mechanical properties, such as their strength, ductility, and corrosion resistance. By adding silicon to aluminum, the resulting alloy is stronger and more durable than pure aluminum, making it suitable for use in high-stress applications such as engine blocks and suspension components.
