Description

(54) СПОСОБ ОБРАБОТКИ УГЛЕРОДИСТОЙ СТАЛИ(54) METHOD FOR PROCESSING CARBON STEEL

33

В качестве примера приводитс  режим обработки углеродистой стали с содержанием углерода 1,29%, полученной из непрерывного слитка и имеющей грубую карбидную и структурную неодпородиость.As an example, the treatment of carbon steel with a carbon content of 1.29%, obtained from a continuous ingot and having a coarse carbide and structural instability, is given.

Указанную сталь подвергали пластической деформации в интервале температур 1150- 750°С с ускоренным охлаждением после окончани  деформации, после чего металл подвергали термической обработке при 1000°С в течение 1 час; после охлаждени  на воздухе металл вновь нагревали до температуры 1000°С и прокатывали на 8 мм с окончанием деформации при 800-750°С и с ускоренным охлаждением после деформации.Said steel was subjected to plastic deformation in the temperature range of 1150- 750 ° C with accelerated cooling after the end of deformation, after which the metal was subjected to heat treatment at 1000 ° C for 1 hour; after cooling in air, the metal was again heated to a temperature of 1000 ° C and rolled to 8 mm with the termination of the deformation at 800-750 ° C and with accelerated cooling after deformation.

В реззльтате прочность на изгиб повысилась на 20-50% по сравнению с известным снособом.As a result, the bending strength increased by 20-50% compared with the known method.
