对低炭钢进行热处理以提高其温度,已有不少人重视:Приданцев等、Н.В.施米德特等试验平炉“钢三”的淬火;Стародубов等也将电炉低炭钢进行了钢质处理;鞍山钢铁公司也用喷水冷却以提高平炉“钢三”强度。我们研究了转炉“钢三”淬火处理。试样是上钢五厂侧吹碱性转炉冶炼的φ55圆钢材。钢的化学成份如下:C0.07～0.09％、Si0.17％、Mn0.34％、P0.012％、S0.036％、N_20.029％。将钢材锻成φ17和φ28圆棒在马弗炉内分别加热到
Low-carbon steel for heat treatment to increase its temperature, many people have attention: Приданцев, etc., Н.В. Schmidt and other test flat hearth “steel three” quenching; Стародубов, etc. will also be electric steel low carbon steel Processing; Anshan Iron and Steel Company also spray cooling to improve open hearth “steel three” strength. We studied the converter “steel three” quenching treatment. The sample is on the steel plant five side blowing alkaline converter smelting φ55 round steel. The chemical composition of steel is as follows: C0.07 ~ 0.09%, Si0.17%, Mn0.34%, P0.012%, S0.036%, N_20.029%. The steel forged φ17 and φ28 rods were heated to the muffle furnace
