Abstract

FIELD: ferrous metallurgy, namely, production of heat treated rolled sheets from carbon and low-alloyed steels. SUBSTANCE: method involves setting temperature and heating rate of metal upon accelerated tempering in dependence upon rate and termination temperature of previous accelerated cooling stage; selecting mean value of sheet cooling rate before tempering in dependence upon carbon equivalent of steel. EFFECT: enhanced mechanical properties of rolled sheets of low carbon steel.

Сущность изобретения заключается в том, что, с целью повышения комплекса механических свойств листового проката из малоуглеродистой стали, температуру и скорость нагрева металла при ускоренном отпуске устанавливают в зависимости от скорости и температуры окончания предшествующего ускоренного охлаждения, причем среднюю скорость охлаждения листов перед отпуском выбирают в зависимости от углеродного эквивалента стали.The essence of the invention lies in the fact that, in order to increase the complex of mechanical properties of sheet metal from mild steel, the temperature and heating rate of the metal during accelerated tempering is set depending on the speed and temperature of the end of the previous accelerated cooling, and the average cooling rate of the sheets before tempering is selected depending from the carbon equivalent of steel.
