Ferro silicon ball

Application prospects of ferro silicon balls: Excess oxygen is dissolved into the molten steel at the end of converter steelmaking and smelting, and the excess oxygen precipitates when the molten steel solidifies to form oxide inclusions and bubbles, and the generated oxide inclusions remain in the steel, which will reduce the plasticity and Impact toughness and other mechanical properties, high oxygen content in steel will also produce defects such as subcutaneous bubbles and porosity, and aggravate the harmful effect of sulfur, directly affecting the quality of casting slabs and steel products.

Advantages of ferro silicon balls: At present, the deoxidation method of steel smelted in steel mills is generally based on aluminum deoxidation. The advantage of aluminum deoxidation is that the aluminum grains are finer and the deoxidation effect is very obvious, but the disadvantage is that the cost of aluminum deoxidation is high, and aluminum The deoxidizer is easy to form Al2O3 inclusions to cause water blocking or non-downflow phenomenon. Therefore, a new deoxidation method (ferro silicon ball) is needed to reduce the cost of deoxidation and solve the problem of water blocking and non-downflow.
