Kassim D. Improvement of domain technology at the expense improvement of quality of charge materials and gas-dynamic conditions of blast furnace operation

The complex of theoretical developments and experimental researches, aimed at in-creasing the efficiency of blast furnace melting in modern fuel-raw materials and technological conditions by improving the gas-dynamic conditions of blast furnace operation and the quality of charge materials is carried out in the dissertation. The acquired scientific knowledge is applied to achieve high blast furnace performance by coordinated control of the operation of the furnace "from above" and "from below". The results of the work are theoretical generalization of scientific approaches to the control and management of smelting technology, depending on the mutual influence of fluctuations of indices of fuel and raw materials conditions and parameters of the blasting melting regime, which solves the important problem of improving the efficiency of smelting of cast iron on blast furnaces of Ukraine.
