METHOD OF STEEL CONTINUOUS CASTING AND METHOD OF SHEET STEEL PRODUCTION Russian patent published in 2014 - IPC B22D11/115 

FIELD: process engineering.

SUBSTANCE: continuous casting of steel with carbon content of 0.003 wt % or less is performed at the machine including two magnet top poles and two magnet bottom poles and immersible pipe with outlet directed downward at 10 degrees or more and smaller than 30 degrees. Fused steel flowing out from said pipe is decelerated by magnetic field of constant current applied to said top and bottom poles. In casting allowed for are steel chemical composition, gradient of tension at boundary layer ah hardening crust front surface to optimise DC magnetic field intensity in compliance with blank width. Said blank is subjected to hot rolling, etching and cold rolling to get hot rolled steel sheet. Time to cold rolling start and/or steel sheet surface maximum temperature is adjusted.

EFFECT: higher quality of sheet steel.
