STEELMAKING OF RUP “BMZ” IN DYNAMICS OF 20 YEARS

In conditions of RUP “BMZ” for the first time in practice of electric steelification in USSR in production quantities the new conception of melting of high level in blast steel-melting furnace has been embedded. The different variants of the out-of furnace processing and deoxidation of cord steel are tested

Perfection of the regime of deoxidation and out-of-fumace processing of cord steel on the basis of information on oxidability of metal

There is developed and introduced the new technology of cord steels production with metal processing by slags of certain constitution and carbon deoxidation at vacuum degasing, that allowed to reduce the pollution of steel with nonmetallics

Intensification of steel melting process in blast furnace by means of bottom blowing by inert gas

With application of physical and mathematical modeling there is carried out complex estimation of efficiency of different kinds of inert-gas flushing of ark steel furnace

New technical solutions and stages of metallurgical equipment reconstruction of RUP Belarussian metallurgical works

The data on the basic stages of reconstruction of the equipment at RUP “Belarusian metallurgical works and program of reconstruction for the period 2000—2005 is cited

The main characteristics of liquid steel

There are given expressions for determination of dependence of the structural-sensitive properties of liquid steel (viscosity, denseness, surface tension, heat conduction and others) on temperature, and also on contents of impurity elements, in particular, on deoxidizers elements, being used at discharging of metal out furnace into bowl

Statistic model of the reduced material balance of melting of liquid semiproduct in the blast steel-making furnace-100 No 3 of RUP “BMZ”

There is developed the model of calculation of the material melting balance in the arc steel-making furnace, allowing to determine mass of liquid steel of fluid melting in furnace, mass of liquid metal in a bowl after its discharging out of furnace and of predictive “marsh " after each carried out melting

Complex technology of assimilation of the ball bearing steel and round billet production in conditions of RUP “Belarussian metallurgical works”

There is worked out the complex (through) technology of production of high-quality ball bearing steel and proved the possibility of slugs production of square 125x125 mm and round section with diameter 130 mm, 115 mm and 90 mm in conditions of RUP '‘Belarussian metallurgical works”

The mathematical modelling of the process of burden dissolving in superpower ark steel-making furnace

There is developed and solved the mathematical model of dissolving process of burden in three-dimensional production, allowing for the peculiarities of modem technologies of steel melting in arc steel-making furnaces
