Such products include complex ferroalloys containing, in addition to iron, two or more functional elements. Complex ferroalloys should be created in the most favorable combination of components, contributing to the necessary effective impact on the quality of the metal being processed, with a high degree of assimilation of useful elements in it. Changes in the characteristics of complex ferroalloy, affecting the assimilation of target (basic) elements, should be carried out by regulating the composition and ratio of elements that can be included in almost any ferroalloy, since they are part of all steels and cast irons or they’re required by the conditions of their smelting. Firstly, these elements should include silicon and manganese. Silicon can reduce the melting temperature, density, and melting time of ferroalloy in the liquid metal. For example, the addition of 1% silicon to low-carbon ferrochrome can reduce the melting point of the alloy by 8–9 degrees. Compositions of new complex ferroalloys of systems Fe-Si-Ca-Ba, Fe-Si-B, Fe-Si-Al-Nb, Fe-Si-Mn-V have been successfully tested and introduced into production.</p> <p class="p1"><span class="s1">Keywords: </span>metallurgy, ferroalloy, melting, density, physical and chemical properties, steel</p&gt;}, number={1}, journal={KnE Materials Science}, author={Ivanovich Zhuchkov, V and Vadimovich Zayakin, O}, year={2019}, month={Mar.}, pages={138–144} }
