Изобретение относитс к области черной металлургии.This invention relates to the field of ferrous metallurgy.
Известен способ термической обработки биметаллических листов с основным слоем из углеродистой стали и плакирующим слоем из нержавеющей стали, включающий нормализацию и последующий отпуск в межкристаллическом интервале температур А-А 1.The known method of heat treatment of bimetallic sheets with a main layer of carbon steel and a cladding layer of stainless steel, including the normalization and subsequent tempering in the intercrystalline temperature range A-A 1.
Недостаткомиизвестного способа вл ютс низкие механические свойства основного сло и низка коррозионна стойкость, вызванные медленной скоростью охлаждени в интервале температур выпадени карбидов.A disadvantage of the well-known method is the low mechanical properties of the base layer and the low corrosion resistance caused by the slow cooling rate in the temperature range of deposition of carbides.
Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс способ термической обработки двухслойной листовой стали с основным слоем из стали 16 ГС и 09Г2С с плакирующим слоем из стали 08X13 и 12Х18Н10Т, включающий закалку с 940-960°С в прессе и последующий отпуск при 680-720°С 2.The closest to the proposed technical essence and the achieved result is a method of heat treatment of two-layer steel sheets with the main layer of steel 16 HS and 09G2S with a cladding layer of steel 08X13 and 12X18H10T, including quenching from 940-960 ° C in a press and subsequent tempering 680-720 ° C 2.
Недостаток известного способа заключаетс в том, что длительность процесса термической обработки велика из-за осуществлени охлаждени в прессе закалки до цеховой температуры, что в свою очередьThe disadvantage of this method is that the duration of the heat treatment process is long due to cooling in the hardening press to the workshop temperature, which in turn
приводит к увеличению расхода энергоносителей при последующем нагреве под отпуск.leads to an increase in energy consumption during subsequent heating under the vacation.
Целью изобретени вл етс сокращение длительности термической обработки и сокращение расхода энергоносител .The aim of the invention is to reduce the duration of heat treatment and reduce the consumption of energy carrier.
Это достигаетс тем, что охлаждение листа в процессе закалки производ т до 450-500°С.This is achieved by cooling the sheet during the quenching process to 450-500 ° C.
