direct smelting of steel: process simulation

the design and manufacture of direct smelting reactors depends on the rate of the physico-chemical reactions that occur in the particles immersed into the molten bath. investigation of the effects of the important parameters that influence the smelting rate of the particles that in the furnace are both difficult and expensive if the aimed is to take measure meuts under real practical conditions. it is feasible of simulate the process through application of the physico-mathematical models that may be capable to predicting the influence of the important variables such as (a) type and dimensions the furnace, (b) analyses of the materials, and (c) size and rate of feeding the particles. in this paper, the operational conditions required to maximize the rates and the efficiencies of heating, reduction, melting and purification of the reactor is investigated.
