The Thermal Shock Resistance of Steel for Cold Working Rolls
-
摘要: 采用摩擦熱沖擊的方法,研究了冷軋工作輥用86CrMoV7鋼在不同熱處理條件下的抗熱沖擊性。結果表明:淬火溫度越高,抗裂性越差。在相同淬火溫度下,回火溫度越高,抗裂性越好。Abstract: The influence of different heat treatment on thermal shock resistance of 86CrMoV7 steel used as cold working rolls, has been investigated by using friction thermal shock method. The results show that under the same quenching temperature, the higher the quenching temperure, the worse the crack resistance and the higher the tempering temperature, the better the crack resistance.
