Аннотация: One of the ways to reduce the cost of casting is to smelt pig iron on a cheap stock, that is, to replace expensive foundry-iron and steel-making iron with steel scrap with its further carbonization. Steel waste is basically much better than foundry-iron and steel-making iron in terms of materials, free from harmful impurities and iПоказать полностьюnclusions. The absence of free carbon in the metal stock makes it possible to obtain any of its content in synthetic iron affecting the structure and properties of cast iron. The process of metal carbonization is the most significant stage in the production of synthetic iron. It largely determines the structure and quality of castings. Therefore, it is very important to study the patterns of dissolution of carbon in the melt. In the course of the study, there were established changes in the parameters of the crystal lattice of quartzite while it was drying using different temperature regimes. These changes further affect the lining resistance during the carburization of the melt. This is due to the fact that the production of synthetic iron from one steel scrap leads to a significant increase in the number of carbonizer (to 40 kg by 1 ton of the alloy), and forces the carbonizing process to proceed at elevated temperatures. For this reason, the sintered lining layer should consist of cristobalite, since it can withstand higher melting temperatures. © 2006-2020 Asian Research Publishing Network (ARPN).
