Abstract
Способ прецизионной обработки экономнолегированных сталей, включающий нагрев под деформацию, охлаждение, нагрев под закалку и закалку с последующим отпуском, отличающийся тем, что сталь перед деформацией подвергают предварительной ковке и закалке с температур ковки, нагрев под деформацию ведут до температур Ac- 5-15ºС со скоростью от 80 до 100 град/мин и выдержкой от 2 до 2,5 ч, деформацию проводят со степенью от 30 до 60%, нагрев под закалку проводят до температур Ac+40-50ºС, а закалку проводят в масло.A method for the precision treatment of economically alloyed steels, including heating under deformation, cooling, heating under quenching and quenching, followed by tempering, characterized in that the steel is subjected to preliminary forging and quenching from the forging temperatures before deformation, and heating under deformation is carried out to temperatures Ac- 5-15 ° C at a speed of 80 to 100 deg / min and a shutter speed of 2 to 2.5 hours, the deformation is carried out with a degree of 30 to 60%, heating under quenching is carried out to temperatures Ac + 40-50ºС, and quenching is carried out in oil.
