Application of ferrosilicon powder in smelting industry?
Ferrosilicon powder is a common deoxidizer in the metallurgical industry, the use of large proportion in the steelmaking industry, we only understand the knowledge of ferrosilicon powder in this respect, in order to better application, then ferrosilicon powder this deoxidizer in the smelting industry is what, the following is a brief introduction.
Oxygen in molten steel is mainly added to remove impurities such as silicon, manganese, phosphorus and carbon in molten steel. At the same time, oxygen is also added to obtain a higher reaction efficiency. Therefore, at the end of smelting, molten steel is in a state of "transition oxidation". Effect of oxygen on steel properties: Oxygen is in the process of steel solidification segregation tendency, one of the serious elements in liquid steel solidification and subsequent cooling process, the solubility of oxygen fell sharply, most of zhongyuan steel dissolved oxygen with iron oxide, sulfur oxides fine inclusions in the form of gamma or alpha enrichment of grain boundary, the fine inclusions can cause grain boundary embrittlement, It is easy to become the starting point of grain boundary cracking during the processing and use of steel, which leads to brittle failure of steel.
Through the above content, we learned the deoxygenation of ferosilicon powder, we only understand the characteristics and role of the product, in order to more convenient our future work, the use of deoxidizer is to reduce the cost of enterprises, improve the economic benefits of an important way. So we have questions about this aspect, you can call to consult my company.
