对钢轧辊孔型进行火焰表面淬火,是冶金工厂提高钢材产量、降低轧辊消耗和减少轧辊储备量的一项有效措施。轧辊孔型表面淬火后,提高了孔型表面的硬度和耐磨性,延长了轧辊的使用寿命,减少了换轧辊次数,提高了轧制吨数。提高钢轧辊的耐磨性,也可从轧辊本身的材质方 Flame surface quenching of the steel roll pass is an effective measure for metallurgical plants to increase steel production, reduce roll consumption and reduce roll stock. Roll hole surface hardening, the hole surface to improve the hardness and wear resistance, extending the service life of the roll, reducing the number of roll change, increased rolling tons. Improve the wear resistance of steel rollers, but also from the roll itself material side
