METHOD FOR HEATING CARBON LOW-ALLOY STEELS FOR ROLLING Russian patent published in 2002 - IPC

Abstract RU 2184786 C2

FIELD: metallurgy, namely processes for heating steel blanks for rolling in continuous, bar rolling and rod rolling mills. SUBSTANCE: method comprises steps of heating blank until preset temperature of its surface at rate (0.065-0.35) C/s; sustaining gas temperature in cementation zone by (100-200)C higher than final heating temperature. EFFECT: lowered time period for heating, enhanced quality of rolled steel, reduced metal loss in furnace, decreased total energy consumption for heating and rolling carbon low-alloy steels. 1 tbl, 2 dwg, 1 ex
