Development of a mathematical model of the process of electric melting of briquetted raw materials

Article preview

Due to the transition to smelting of unburnt briquetted flotation concentrate in ore-thermal furnaces of Pechenganickel smelting shop (JSC "Kola MMC") it seems reasonable to determine the optimal conditions of electric smelting technology. The mathematical models of smelting technology and shop technology as a whole have been developed and a computer program for their solution has been created, a comparative analysis of technology indicators using existing and new raw materials has been carried out.

Assessment of energy performance of copper-nickel electric smelting during the transition to a new type of feed materials

Article preview

Due to the upcoming change in the composition of raw materials processed in the smelting furnaces of Pechenganickel Plant (OJSC Kola MMC), i.e. the transition to smelting of unburnt briquetted flotation concentrate, the specific electricity consumption for smelting was assessed. For this purpose, the indicators of electric furnaces of the smelting shop for 20 years with different charge compositions were processed by the method of correlation and regression analysis. It is established that the main factors determining specific electric power consumption are iron content in slag and matte and electric load of furnaces. A regression equation has been obtained that makes it possible to calculate the electric power consumption for melting for new charge compositions. For briquettes, the expected specific consumption is about 800 kW per 1 ton of metal-containing solid charge.
