CAST OF HIGH CARBON STEEL OF CORD QUALITY ON UNRS OF SMALL CUT

The investigated new reduced technological schema showed the possibility of the production of high carbon steel of cord quality with metal cast at UNRS of light section in conditions of ESPTs-1

PERFECTING OF THE TECHNOLOGY OF THE OUT-OF-FUMACE PROCESSING OF STEEL AT RUP “BMZ” BY THE EXAMPLE OF ESPTS-1

There are achieved all production-technological figures, concerned with embedding of the out-of-furnace processing “bowl- furnace'' installation, i.e the casting duration in the steel-making furnace is reduced, the consumption of electrodes per one ton of good steel is reduced, and also the consumption of refractory bricks is reduced and metal overflows into furnace are excluded

NEW TECHNOLOGIES OF CONTINUOUS CAST OF STEEL AT MODEMIZATION OF STEEL-MAKING OF RUP “BMZ”

The possibilities of perfection of the processes of the metals continuous casting, including at the reconstruction of operating equipment without considerable capital costs, are shown

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

THE WAYS OF INCREASE OF THE MODEM ARC STEEL-MAKING FURNACES CAPACITY

The main ways of intensification of melting processes in the modern high-capacity electric arc furnaces of alternating current are examined, their advantages in the field of application are shown

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

DEVELOPMENT OF THE TECHNOLOGY OF THE OUT-OF-FUMACE STEEL PROCESSING BY POWDER WIRES AT RUP “BMZ”

The world metal market showed that available way of the out-of-furnace processing are not enough for providing of the metal production competitiveness. At present time powder wires with fillers of silicocalcium. carbon, sulfur, ferrotitanium, ferroboron are widely applied at the works and out-of-furnace processing of steel by powder wires has become integral components of technology

ABOUT THE POSSIBILITY OF THE METAL OF CORD QUALITY PRODUCTION WITHOUT USING OF VACUUMATOR ON THE FIRST LINE OF RUP “BMZ”

The new approach to the description of the nonmetallics elimination process in the process of the out-of -furnace processing using hydrodynamic and physical-chemical models is offered. The possibility of control of the nonmetallics elimination process in the course of processing at the installation *furnace-bowl” is shown

OPTIMIZATION OF THE PRODUCTION OF STEEL WITH NORMABLE SULFUR CONTENT

The offered technology allowed to carry out the transformation aluminate impurities, to prevent the fall of hard sulfide calcium and as a result to exclude tightening of the steel-bowl gate at continuous steel cast with the normed content of sulfur and aluminium
