Study Of Saving Energy And Reducing Consumption Of No.1 BF Some Iron And Steel Corporation

In recent years, along with China's iron and steel output increasing sharply and the production scale unceasing expansion, the proportion that the iron and steel industry energy consumption occupied the national total energy consumption already rised from 80's 10% to present about 14%, therefore, reducing energy consumption has become a difficult problem which iron and steel enterprise compels to resolve in our country.The energy consumption of iron-smelting occupies the iron and steel industry total energy consumption about 40%, which is the first big household among the iron and steel enterprise energy consumption. Doing well the energy conservation of iron-smelting is significant not only for reducing China's iron and steel industry energy consumption, but also for guaranteeing the goal that the iron and steel industry reducing energy consumption to realize.In view of the present situation that No.1 BF of some iron and steel corporation which energy consumption is too higher, based on more detailed measurement, analysis and evaluation of the metallurgical performance of the raw charge, fuel, the synthesis furnace burden and the situation of the BF energy utilization for the first time. Using the blast furnace production static model (carbon ratio chart and Rister operates graph) and the regression analysis model, the potential of reducing energy consumption and the relationship between some operation parameters and energy consumption of this BF were analyzed. What's more, formulating concrete measures which reducing energy consumption combining the present situation of the iron and steel corporation. The main parts of this paper as follows:Determinating the metallurgical properties of raw material and complex BF burden of No.1 BF in this iron and steel corporation through experiments, and comparing with other domestic same type BF. Finding the way and direction that improving the metallurgical properties of the raw material and the structure optimization of complex BF burden.It can provide basis for improving beneficiated materials level of this BF and promoting the BF reducing energy consumption.Carrying on the thermal equilibrium test and analyzing the condition of energy utilization of the blast furnace at present. According to the previous computational and analysis results, establishing this blast furnace production static model (carbon ratio chart and Rister operates graph), analyzing saving energy conservation potential and the influence that the correlation controlled variable to its energy consumption.As well as based on this BF actual production history data, formulating linear regression model, analyzing the influence of this BF operate parameters to its energy consumption.Accoding to above analysises, making out effective measures to reduce the energy consumption of the No.1 BF of the iron and steel corporation.
