通过实验对比分析了调质前后的矿井支护钢的力学性能,并经过等值代替理 论的计算分析,为论证矿井支护钢调质处理的必要性和优越性提供了必要的理论 依据。
The mechanical properties of mine supporting steel before and after quenching and tempering were comparatively analyzed by experiments and the calculation and analysis of equivalent replacement theory were carried out to provide the necessary theoretical basis for demonstrating the necessity and superiority of quenching and tempering of mine supporting steel.
