What is silicone carbide?


Silicon carbide for steelmaking is a novel high-performance composite deoxidizer that can be used to replace traditional deoxidizers such as ferrosilicon powder and alloy powder, thereby reducing costs.

The role of Silicone carbide in steelmaking


Deoxygenation
During the steelmaking process, molten steel often contains a large amount of oxygen, which can cause oxidation of the molten steel and reduce the quality of the steel. Silicon carbide can react with oxygen in molten steel to generate carbon dioxide, thereby effectively removing oxygen from molten steel. This is the so-called deoxidation. Through the deoxidation of silicon carbide, the oxygen content in the molten steel can be significantly reduced, and at the same time, the occurrence of defects such as subcutaneous bubbles and looseness can be reduced, thereby improving the quality of the molten steel.

 

Desulfurization
In addition to deoxidation, silicon carbide can also play a desulfurization role. During the steelmaking process, sulfur in the molten steel will increase the brittleness of the steel and reduce the mechanical properties of the steel. Silicon carbide can react with sulfur in molten steel to generate sulfate, thereby effectively removing sulfur from molten steel and improving the mechanical properties of steel.

SiC

Stable molten steel quality
Silicon carbide can also stabilize the quality of molten steel. In the steelmaking process, the quality of molten steel directly affects the quality of steel. Silicon carbide can react with impurities in molten steel to form stable compounds, thereby stabilizing the quality of molten steel. In addition, silicon carbide can also refine the crystal grains of molten steel, remove harmful impurities in the molten steel, and further improve the quality of steel.

 

Increase the molten steel casting temperature
Silicon carbide can also increase the casting temperature of molten steel. In the steelmaking process, the casting temperature of molten steel directly affects the solidification structure and properties of the steel. Silicon carbide can increase the casting temperature of molten steel, thereby making the solidification structure of the steel more uniform and improving the performance of the steel.

 

Silicon carbide also has the function of protecting the furnace wall and extending the life of the furnace wall in steelmaking. During the steelmaking process, the furnace wall is easily eroded by molten iron and slag, leading to thinning, deformation, and even leakage of the furnace wall. Silicon carbide can reduce the oxidation of molten iron and reduce the oxidative erosion of the furnace wall, thereby protecting the furnace wall and extending the service life of the furnace wall.

 

In addition, silicone carbide can also be used as an alloy additive in steelmaking. Under specific smelting conditions, silicon carbide can react with other alloying elements to form specific alloy phases, further improving the properties of steel. For example, in the production of ductile iron, silicon carbide can be used as a powerful deoxidizer to reduce the amount of spheroidizing agent added, increase the spheroidization rate, eliminate the oxidation factors of molten iron, and extend the life of the furnace wall.
