Abstract
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 °C, the hardness increases with the increase of temperature, and when quenching temperature is higher than 900 °C, the hardness decreases with the increase of temperature. As quenching temperature is lower than 920 °C, the effect of quenching temperature on the impact toughness is not obvious. When quenching temperature is higher than 920 °C, impact toughness decreases with the increase of temperature. When tempering temperature is higher than 450 °C, the hardness begins to decrease obviously. After tempering at 350 °C, the best wear resistance was obtained. According to the service condition of rolling mill torus liner, the MLAWS is quenched from 900–920 °C and tempered at 350–370 °C.
