How to choose a good ferrosilicon 65? Here is a brief introduction:
Silica is the factor affecting the quality of ferrosilicon 65: the raw material of ferrosilicon 65 is silica. Good silica has the characteristics of uniform impurity content and particle size of silica, but we must pay attention to the particle size of silica. Too small particle size will contain too many impurities, which will affect the permeability of fabric. Too large particle size is easy to cause charge stratification and slow down the melting and reduction reaction speed of charge.
Coke also plays a vital role in the quality of ferrosilicon 65: coke also plays a vital role in the production of ferrosilicon 65. In the selection of good coke, it is easy to produce good ferrosilicon 65, and the ash and moisture in coke are the reasons that affect the quality of coke. Good coke has the characteristics of low ash and moisture, and high ash coke is easy to cause slag sintering of fabric in the furnace and affect the permeability of fabric. Higher moisture content is an important factor causing the fluctuation and deterioration of furnace conditions.
