Calcium Silicon Alloy Lumps

 

Types of Calcium Silicon

Calcium silicon 15%: Contains approximately 15% silicon, this grade is commonly used as a deoxidizing agent in steel manufacturing.

 

Calcium silicon 25%: With a higher silicon content, it’s ideal for applications that demand superior fluidity and mechanical strength.

 

Calcium silicon in lump form: Typically used for feeding into furnaces, this form provides great convenience and efficiency.

 

Calcium silicon in powder form: This variant is preferred for easy integration into various metallurgical processes.

 

Calcium Silicon Alloy Uses

 

 

Application of calcium silicon alloy in steel metallurgy: Calcium silicon alloy is an important alloy additive in steel metallurgy. By adding calcium silicon alloy, the toughness and strength of steel can be increased, and the heat treatment properties of steel can be improved. Calcium silicon alloy can also reduce the sulfur content in steel and improve the quality and performance of steel.

 

Application of calcium silicon alloy in the foundry industry: Calcium silicon alloy is widely used in the foundry industry. It can be used as a deoxidizer and added to casting materials to reduce the oxide content in castings and improve the quality of castings. In addition, calcium silicon alloy can also be used as a rare earth alloy additive for casting materials to improve the mechanical properties and surface quality of castings.

 

Application of calcium silicon alloy in the metallurgical industry: Calcium silicon alloy is also widely used in the metallurgical industry. It can be used as a desulfurizer to remove sulfur from steel and iron during steelmaking and ironmaking. In addition, calcium silicon alloy can also be used as an alloy additive for smelting alloys to improve the hardness, strength and wear resistance of the alloy.

 

Application of calcium silicon alloy in the electronic industry: Calcium silicon alloy also has important applications in the electronic industry. It can be used as a semiconductor material in the manufacture of electronic components, integrated circuits and solar cells. The electrical conductivity and stability of calcium silicon alloy make it an indispensable material in the electronics industry.

 

How To Produce Calcium Silicon
 

There are three kinds of production methods of silicon calcium alloy: mixed feeding method, layered feeding method and two-step method.

Si58Ca30硅钙合金

Mixed feeding method

The mixed feed method is to add silica, lime and coke to the reduction furnace. CaO and SiO2 are simultaneously reduced with carbon to calcium-silicon alloy. The reaction is caO+3SiO+7c=Casi2+Si+7CO

 

The disadvantage of this method is that calcium oxide and silicon dioxide come into contact to form a low melting point silicate. It is difficult to reduce silicon and calcium from silicates. Based on this situation, the layered feeding method is developed.

Layer feeding method

The purpose of this method is to reduce the contact between calcium oxide and silicon dioxide to reduce the formation reaction of Cao-siO2.

 

The layered feeding method is to first add lime and coke near the electrode, and melt the CaO to produce CaC2 as much as possible. Silica is then mixed with the remaining carbon and added to the furnace to produce a calcium-silicon alloy.

Two-step method

Silicon calcium and gold are first produced in an electric furnace. Then calcium silicon and gold are produced in the second circuit using calcium carbide, silica and carbonaceous reducing agent as raw materials.

 

The main advantage of this production method is that it can produce silicon calcium and gold with high calcium content. And the operation is relatively simple. Two electric furnaces can use calcium carbide to produce calcium silicon and gold.

FAQ

 

Q: What is the use of calcium silicon?

A: Calcium-silicon is used mainly for steel production, as it allows inclusive treatments as well as deoxidising and de-sulphuring of liquid steel. This process that we use improves inclusive properties, the fluidity of continuum casting, transversal mechanical properties and use in factories.

Q: What is calcium silicate good for?

A: Cacium silicate (Ca2SiO4), also known as calcium silicon oxide, is a product derived from limestone and diatomaceous earth, and is used in the pharmaceutical industry as an anticaking agent. Anti-caking agents absorb moisture and allow products to flow freely during the manufacturing process.

Q: Can calcium silicate get wet?

A: Calcium silicate or perlite insulations are manufactured with anti-corrosive silicates that help prevent corrosion even if the insulation gets wet.

Q: What removes calcium silicate?

A: The only reliable way to remove calcium silicate deposits is with a pumice stone — and a lot of hard work. These stains are notoriously difficult to scrub free. If you have a vinyl or fiberglass pool, you won't be able to use a pumice stone. It would scratch the pool.

Q: Is calcium silicate fireproof?

A: Fire Resistance: One of the most prominent features of calcium silicate boards is their exceptional fire resistance. They are non-combustible and can withstand high temperatures for extended periods without burning or releasing harmful fumes.

As one of the leading calcium silicon manufacturers and suppliers in China, we warmly welcome you to buy high-grade calcium silicon in stock here from our factory. All metal materials are with high quality and low price.
