摘要: 为提高高碳H13钢表面硬度及耐磨性能,对高碳H13钢进行了渗碳+调质处理,并对渗碳层组织、硬度进行了分析。结果表明,渗碳+调质处理可提高高碳H13钢的硬度;高碳H13钢经920 ℃渗碳、1050 ℃油淬和510 ℃回火后的硬度最高。采用该工艺处理的高碳H13钢刀圈相比仅调质处理的高碳H13钢刀圈,在同等磨损条件下的掘进距离提高约36%。

Abstract: In order to improve the surface hardness and wear resistance of high carbon H13 steel, carburizing+quenching and tempering processes were carried out, and the microstructure and hardness were analyzed. The results show that the carburizing+quenching and tempering processes can significantly improve the hardness of the steel. After carburizing at 920 ℃, quenching at 1050 ℃ and tempering at 510 ℃, the hardness of the high carbon H13 steel is the highest. Compared with that treated only by quenching-tempering, the high-carbon H13 steel cutter ring treated by this process can increase the tunneling distance by about 36% under the same wear conditions.

Key words: H13 steel, carburizing, tempering temperature, hardness, tunneling distance
