Abstract
Способ термической обработки листового проката из низкоуглеродистой феррито-перлитной стали, включающий предварительную деформацию при температуре 1000-850°C с суммарным обжатием 65-75%, окончательную деформацию при температуре 750-700°C с обжатием за проход не менее 12% и суммарным обжатием не менее 60%, последующую закалку с прокатного нагрева со скоростью более 35°C/мин до температуры 150±10°C, затем - на воздухе, далее высокий отпуск с последующим охлаждением на воздухе, отличающийся тем, что высокий отпуск осуществляют при температуре 600±10°C с выдержкой 4,0-6,0 мин/мм толщины, после него проводят стабилизирующий отпуск при температуре 460+10°C с выдержкой 3-5 час с последующим охлаждением на воздухе. The method of heat treatment of sheet metal from low-carbon ferritic-pearlite steel, including preliminary deformation at a temperature of 1000-850 ° C with a total compression of 65-75%, final deformation at a temperature of 750-700 ° C with a compression per pass of at least 12% and total compression not less than 60%, subsequent quenching from rolling heating at a rate of more than 35 ° C / min to a temperature of 150 ± 10 ° C, then in air, then high tempering followed by cooling in air, characterized in that high tempering is carried out at a temperature of 600 ± 10 ° C with Coy 4,0-6,0 min / mm thickness, is carried out after stabilizing tempering at a temperature of 460 + 10 ° C with a delay of 3-5 hours followed by cooling in air.
