High Level Metal Ferro Silicon 70

It is extremely widely used in steelmaking, cast iron, non-ferrous metal industry, and is a good deoxidizer, alloying agent and additive. Therefore, it is very important to determine the silicon content in ferrosilicon 70. At present, the main methods for determining the silicon content in ferrosilicon are perchloric acid dehydration gravimetric method, animal glue coagulation gravimetric method, potassium silicate fluoride capacity method, density method, and silicon-molybdenum blue light.

1.The determination of carbon and sulfur content in ferroalloy products is based on ferrosilicon 70 most commonly, with the emergence of low-carbon ferrosilicon (cC<0.015%) and high-purity ferrosilicon (cC<0.0030%), carbon and sulfur content has become a mandatory element in the analysis, and the accurate determination of its content is particularly important. The determination of carbon and sulfur content in ferrosilicon is a variety that is difficult to measure in ferroalloy products, the reason is that it is difficult to burn the ferrosilicon sample, and the carbon and sulfur content in low-carbon ferrosilicon is much lower than that in ordinary ferrosilicon, which increases the difficulty of accurately determining the carbon and sulfur in low-carbon ferrosilicon.
