摘要/Abstract

摘要： 针对木材削片机刀片的服役条件,对60Si2Mn热轧钢刀片采用不同的预备热处理和强韧化热处理工艺,测试了其显微组织、抗弯强度、冲击性能及耐磨性,优化了60Si2Mn热轧钢刀片的热处理工艺。结果表明,60Si2Mn热轧钢经过双细化球化退火预先热处理,在900～930 ℃淬火和在300～310 ℃回火的马氏体级别为1级,能获得良好的强韧性配合。经900 ℃淬火+310 ℃回火后,60Si2Mn热轧钢刀片的抗弯强度达4350 MPa,挠度为12.4;冲击吸收能量为10.3 J;98 N载荷磨擦4 h的总磨损量为14 mg,可以满足轻载削片机刀片的技术要求。

Abstract: In according with the service conditions of wood-chip cutting machine, the preparatory heat treatment and strengthening and toughening heat treatment processes were designed for the 60Si2Mn hot-rolled steel blades, and the metallographic structure, bending strength, impact property and wear resistance were tested, and the heat treatment process of the cutting machine blades made of 60Si2Mn hot-rolled steel was optimized. The results show that the 60Si2Mn hot-rolled steel blades can obtain good combination of strength and toughness after double-refinement spheroidizing annealing, and quenching at 900-930 ℃ and tempering at 300-310 ℃, which the martensitic grade is grade 1. When quenched at 900 ℃ and tempered at 310 ℃, the bending strength reaches 4350 MPa, the impact absorbed energy is 10.3 J, and the total wear mass loss under the load of 98 N for 4 h is 14 mg, which fully meets the technical requirements of the blades of the light duty wood-chip machine.
