摘要
与淬回火调质钢相比,空冷非调质钢不但能减低成本,而且可避免热处理所引起的零件变形.磨削强化处理技术是利用磨削热替代高、中频感应淬火热源对钢件表层进行强化处理,将磨削加工与表面强化合为一体.针对非调质钢进行磨削强化研究,通过变切深和变进给磨削强化试验,研究强化层深度的变化规律,对试件的金相组织进行分析.研究结果表明非调质钢磨削强化是可行性的,研究结论为进一步研究非调质钢磨削强化工艺打下了基础.
By comparison with quenching and tempering steels the non-quenched-tempered steels not only decrease produetion cost but also can avoid deformation of parts by heat treatment. Grinding hardening, the technology of hardening steel piece surface with grinding heat instead of high or medium frequency induction hardening heat, can integrate grinding surface hardening. This paper tries to carry out test study on grinding hardening of non- quenched and tempered steel. Through carrying out the grinding experiments with variable cut depths and feed speeds, the changing law of depth of hardening layer is studied, and the mierostrueture of test-piece is analyzed. Experimental results show the feasibility of grinding hardening of non- quenched and tempered steel, and the conclusion of this paper can lay the foundations of grinding hardening technology of non-quenched and tempered steel piece.
