What is the role of silicon aluminum-calcium alloy

The role of silica-aluminum-calcium alloy

Silicon aluminum calcium has a good deoxidation and purification of steel, silicon aluminum calcium has a variety of deoxidation elements, low melting point, fast diffusion, deoxidation effect is obvious. Calcium also has a good desulphurization effect, and can adsorb inclusions in steel, easy to float out, significantly improve the fluidity of molten steel, played a purification of molten steel, to prevent the problem of water nodules


In the production process, the product can also be made into silicon aluminum according to the requirements of the manufacturer. Calcium balls, silica-aluminum calcium particles, silica-aluminum calcium powder, etc., reduce pollution, facilitate smelting absorption, improve the operating environment.

 Silicon-aluminum-calcium alloy Features

Advantages of silica-aluminum-calcium alloys

silica-aluminum-calcium alloy deoxidizer is suitable for electric furnace, converter, intermediate frequency furnace smelting, can replace aluminum wire, silica-calcium, silica-aluminum, calcium aluminate, etc. better meet the deoxidation, desulfurization, refining and other operational requirements of molten steel, suitable for smelting HRB235, HRB335, HRB400 and other steel grades. Silica-aluminum-calcium alloy has low melting point and rich alloy components, which can be quickly melted in liquid steel to form a strong reducing atmosphere, which can effectively prevent the oxidation of metal elements and improve the metal recovery rate.


Silicon-aluminum-calcium alloy Features:

1. Silicon-aluminum-calcium alloy has a variety of deoxidation components, has the characteristics of low melting point, fast diffusion, full deoxidation, promote desulfurization.

2. The calcium-based elements in Si-AlCa alloy can effectively spherodize the inclusion of molten steel, change the form of the inclusion, and thus play a role in purifying molten steel.

3. Silicon aluminum-calcium alloy is widely used in the process of rapid pre-furnace steel production, refining outside the furnace, which can improve the smelting speed, shorten the smelting time, and reduce the cost of steelmaking.

4. Silicon aluminum-calcium alloy can replace 20% of aluminum wire and 30% of silicon calcium wire as final deoxidizer and alloying agent. In the smelting process, tons of steel can save alloy 1-1.5Kg, save power consumption 9-12Kwh, and comprehensive cost savings of 5-8 yuan/ton of steel.

5. Silicon-aluminum-calcium alloy is easy to put and smoke-free, dust-free, tasteless, fluoride-free, and does not cause damage to the health of operators.

6. Silica-aluminum-calcium alloy does not absorb moisture, does not powder, good stability, easy to preserve.
