How to choose a good ferrosilicon 65? Anyang Xinshichuang ferroalloy briefly introduces to you:

Silica is a factor that affects the quality of ferrosilicon 65: the raw material of ferrosilicon 65 is silica, and a 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, which is too small to contain too many impurities, affecting the breathability of the fabric, too large, easy to cause the derangement, slow down the melting and reduction reaction speed of the 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 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 ash and low moisture, higher ash coke, easy to cause slagging sintering in the furnace fabric, affecting the permeability of the fabric. High moisture is an important factor in the fluctuation and deterioration of furnace conditions

The above is our company's advice, I hope to help you!
