对比研究了60Si2MnA钢带经连续热处理和3种不同的淬火油淬火加回火热处理后的组织与性能。结果表明,钢带经不同的淬火油淬火,并经过400℃,1 200 s回火后,均可获得回火屈氏体组织。钢带经快速淬火油KR128室温淬火后400℃回火,其力学性能与连续热处理接近。
The microstructures and properties of 60Si2MnA steel strip after continuous heat treatment and three different quenching and quenching and tempering treatments were studied. The results show that the tempered troostite can be obtained after the steel strip is quenched with different quenching oil and tempered at 400 ℃ for 1 200 s. Steel quenched by rapid quenching oil KR128 tempered at room temperature after tempering 400 ℃, its mechanical properties and continuous heat treatment close.
