Muravyova I. Development of scientific principles to improve the blast-furnace melting technology with the use of stationary control systems of burden filling surface

Technological process of blast-furnace smelting. Development of scientific bases of integrated use of information systems for measuring stationary surface profile of burden for the control, forecast and management of blast furnace. Development of methods for monitoring, forecasting and management of blast-furnace smelting with the use of objective information about the parameters of the surface charge on the furnace throat with stationary systems for measuring the surface profile. Mathematical modeling and experimental studies and industrial tests. The nature of the changes the speed of lowering the surface charges materials on the cross-section of the shaft blast furnace. Methods for prediction of silicon content in cast iron are developed. Proposed parameters of stability, lowering the burden in some areas and all along on the section of the throat furnace. Methods for evaluation of gas-dynamic regime of the furnace are developed. On the basis of information profilemeter are developed method for rapid assessment of the distribution of materials in the areas throat furnace. The technological requirements for the installation of fixed systems of measurement of surface profile burden on the blast furnaces equipped with bell-less top are formulated. Introduced. Metallurgy, blast furnaces works.
