description: This work analyzes the technology of smelting stainless steels in the conditions of LLC Â«OMZ SpetsstalÂ» using the example of steel grade 06Ð¥12Ð3Ð. In the course of this work, the technologies for smelting steel 06Ð¥12Ð3Ð were considered by studying the technological instructions of the enterprise LLC Â«OMZ SpetsstalÂ». The material and heat balances were also calculated, which were later compared with the initial melon maps of the heats. When calculating material and heat balances, some assumptions were made: - During melting, the elements of the charge will go into slag, and not burn out (this item does not apply to the elements C, Cu, Ni, since their waste will be calculated based on the first and last metal samples) - The mass of the metal does not change during melting - The calculation of elements that have passed into the slag is carried out according to the last sample of the slag - The carbon of the charge materials is oxidized to CO Based on the data obtained in the calculation, conclusions were drawn about the melting of stainless steels in the conditions of LLC Â«OMZ SpetsstalÂ». The most effective was smelt No. 120230, since with a 4.5% discrepancy between the yield and the loaded materials, it was possible to reduce energy consumption by 15-30% relative to other smelts, which has a positive effect on the economic component of steel production. Thus, it can be concluded that the optimal smelting technology is smelting with the use of "swamp" about 20-30% of the total mass of the loaded materials. This technology makes it possible to optimally use the energy of the "swamp" to melt the rest of the charge materials, which, in turn, significantly reduces the time the furnace is energized, and as a result, the overall power consumption.
