description: The topic of the final qualification work: "Development of technological measures aimed at reducing chromium carbon monoxide during the smelting of corrosion-resistant steel grades in an arc steelmaking furnace in the conditions of JSC Metallurgical Plant Petrostal". This work is devoted to the study of the influence of various production parameters on chromium losses during the melting of stainless steels such as 12X18H10T, 20X13, 15X11MF on EAF. The parameters under study include: the amount of silicon supplied to the filling, the temperature of the metal at the outlet from the EAF, the amount of carbon in the steel, as well as the type of chromium-containing materials used. The main tasks to be solved during the work: 1. Study of the features of the production of stainless steels. 2. Identification of factors affecting chromium losses on EAF. 3. Data collection for industrial research. 4. Analysis of the influence of factors affecting chromium losses and their mathematical assessment. The analyzed data were obtained from melting charts at the enterprise of JSC Metallurgical Plant Petrostalâ. Based on the results of processing melting maps, chromium loss was calculated, and corresponding dependencies were built using Microsoft Excel and Advanced Grapher programs. A Cheddock scale rating system was used to mathematically assess the correlation of parameters for chromium losses.
