摘要

The effects of heat treatment on the properties of multi-element wear-resistant low-alloy steel (MLAWS) which is used to make the liner of rolling mill torus were researched. The results show that when quenching temperature is lower than 900 deg C, the hardness increases with the increase of temperature, and when quenching temperature is higher than 900 deg C, the hardness decreases with the increase of temperature. As quenching temperature is lower than 920 deg C, the effect of quenching temperature on the impact toughness is not obvious. When quenching temperature is higher than 920 deg C, impact toughness decreases with the increase of temperature. When tempering temperature is higher than 450 deg C, the hardness begins to decrease obviously. After tempering at 350 deg C, the best wear resistance was obtained. According to the service condition of rolling mill torus liner, the MLAWS is quenched from 900 - 920 deg C and tempered at 350 - 370 deg C.
