STEEL CONTINUOUS CASTING METHOD Russian patent published in 2009 - IPC B22D11/00 B22D11/14 

FIELD: metallurgy.

SUBSTANCE: invention concerns ferrous metallurgy. Particularly it concerns methods of steel continuous casting on continuous-casting plant. During the method implementation it is feeding of liquid steel from ladle into intermediate ladle and then through immersible sleeve to crystallisers, forming in crystallisers sections, its withdrawal from crystallisers and cooling in area spray cooling chamber. Withdrawal of sections from peripheral crystallisers is implemented at a rate higher withdrawal rate from central crystallisers for 0.01-0.1 m/min subject to steel temperature in crystalliser, at that at reduction of metal temperature in peripheral crystallizer for 1°C in comparison with central crystalliser, withdrawal rate from peripheral crystalliser is increased by 0.01 m/min.

EFFECT: invention provides improving of continuous-casting plant productivity, cost cutting and macrostructure improving of sections.
