Distribution of supplemental fuel and oxygen among furnaces in blast furnace shop

At the present time each metallurgical company should solve independently questions of optimization of a charge composition including the economic criteria, to estimate rationality of usage of various fuel and energy resources, to define management strategy of complex metallurgical aggregates. The special place in this complex of operations of reception of metal products is taken away to domain repartition as to the most power-intensive and difficult on which fraction it is necessary to 50 % of fuel used in iron and steel industry. According to forecast prices for coke, finely pulverized coal fuel, natural gas will continue to grow in the nearest and long-term perspective. For a given overall consumption of these resources for the blast-furnace plant is advisable to have an operative technique of estimation of usage efficiency of fuel and energy resources for separate blast furnaces and to carry out an optimal allocation. This task is actual for the large blast-furnace plants involving to 10 blast furnaces, that smelting to 30 thousand tons pig- iron in a day for what it is used about 45 thousand tons iron-ore materials, 13 thousand tons of coke, 3, 5 million m3 technological oxygen, to 4, 0 million m3 natural gas.
