Product Introduction

The production process of metallic silicon

The main raw materials for metallic silicon are silica, petroleum coke, wood chips, etc., which are smelted by electric furnaces

Wash and select the raw material silica

After screening and drying, ingredients are prepared in different proportions according to the type of reducing agent used. The proportions of each material are controlled by a computer program and collected from the material bin onto a belt. The mixture is mixed through the feeding process and enters the electric furnace; The highly automated and scaled feeding process is continuous

Lead to current on the electrode

Heating the material inside the skull to a high temperature of over 1800 degrees Celsius, silicon is reduced in the skull and becomes liquid. It is released through the silicon outlet and cast into silicon ingots, which are then crushed and packaged according to the required size.

Using a mixture of oxygen and air for bottom blowing

The bottom blowing oxygen permeable brick is installed in the bottom of the package, and there are many fine copper pipes inside the permeable brick. Oxygen and air are blown from the fine copper pipes into the silicon melt for refining. After the oxygen blowing is completed, air also forms positive pressure into the silicon melt through the permeable brick.

The refining process requires stirring, which is carried out using compressed air stirring

Its purpose is to improve the kinetic conditions of slag metal element phase reaction, accelerate slag making, remove impurities as soon as possible, reduce heat loss and silicon liquid sticking.

Production of organic silicon such as silicone rubber, silicone resin, and silicone oil

fearures

Silicone rubber has good elasticity and high temperature resistance, and is used to make medical supplies, high-temperature gaskets, etc

Silicone resin is used in the production of insulation paint, high-temperature coatings, etc

Production of organic silicon such as silicone rubber, silicone resin, and silicone oil

fearures

Silicone oil is an oily substance, and its viscosity is minimally affected by temperature

Used for producing advanced lubricants, polishing agents, fluid springs, dielectric liquids, etc,

It can also be processed into a colorless and transparent liquid, which can be sprayed as a high-grade waterproof agent on the surface of buildings

Manufacturing high-purity semiconductors

fearures

Modern large-scale integrated circuits are almost always made of high-purity metallic silicon

Moreover, high-purity metallic silicon is still the main raw material for producing optical fibers

and it can be said that metallic silicon has become a fundamental pillar industry in the information age.

Silicon aluminum alloy is the most commonly used silicon alloy

Silicon aluminum alloy is the most commonly used silicon alloy. Silicon aluminum alloy is a strong composite deoxidizer, which can replace pure aluminum in the steelmaking process to improve the utilization rate of deoxidizer, purify steel liquid, and improve steel quality. Silicon aluminum alloy has low density, low coefficient of thermal expansion, good casting and wear resistance. The alloy castings cast with it have high impact resistance and good high-pressure density, which can greatly improve their service life. It is commonly used in the production of aerospace and automotive components.

Silicon copper alloy has good welding performance and is not easy to generate sparks when subjected to impact. It has explosion-proof function and can be used to make storage tanks.

Adding silicon to steel to make silicon steel sheets can greatly improve its magnetic conductivity, reduce hysteresis and eddy current losses, and can be used to manufacture iron cores for transformers and motors, improving their performance.
