company news about Deoxidation of ZhenAn silicon carbon balls

When smelting medium and high carbon steel in converter, it is generally adopted to add alloy and carburetor at the bottom of ladle with steel flow during tapping to complete the tasks of carburizing and deoxidizing alloying.

Compared with the silicon carbon ball method, this method brings many disadvantages. Because the carburetor is granular, 45 silicon carbon balls are added when the carburetor particle size is large, and the silicon carbon ball heating agent floats on the steel surface, the carbon recovery rate is low, generally 80-90%. The particle size is small, and it is easy to oxidize, the carbon is unstable, and the addition amount is large, the cost is high, which worsens the working conditions;

Secondly, the granular carburetor is easy to cause large heat loss of molten steel boiling in the ladle, which is not conducive to temperature control; Silicon carbon spheres can play a good role in deoxidation. The use of silicon carbon spheres in the steelmaking industry can reduce the deoxidation time by 10~30%, which is mainly due to the rich silicon content in the silicon carbon spheres. Silicon is an indispensable important deoxidizing element in steelmaking. People with good chemistry know that silicon and oxygen have a very stable affinity, which can generate silicon dioxide. Silicon carbon spheres contain rich silicon, Therefore, the use of silicon carbon spheres for steelmaking can play a rapid deoxidation application.
