150CrNiMo低合金过共析铸钢轧辊广泛用于热轧生产中,其寿命为铸铁和锻钢轧辊的3～4倍。钢坯连轧机的精轧和预精轧所用的铸钢轧辊需在500～700℃低温退火,以消除内应力。而承受大负荷的粗轧及其他机架轧辊则
150CrNiMo low alloy eutectoid cast steel roll is widely used in hot-rolled production, the life of cast iron and forged steel rolls 3 to 4 times. Billet rolling mill finishing and pre-finishing cast steel roll used in the 500 ~ 700 ℃ low temperature annealing, to eliminate the stress. Rough rolling and other heavy-duty rollers under heavy load are however
