摘要

本文介绍了对坯料进行金相研究的结果,以及从斜轧机轧制过程中形成的钢球中采集的样品。库存材料为100Cr6轴承钢和钢轨废料钢。轧制过程在常规方法(以下简称常规轧制)和改进方法(以下简称改进轧制)两种假设下并行进行。轧制过程结束后,采用三种冷却介质:空气、水和油。下面的图片是用明光场和暗光场显微镜技术拍摄的,样品用4%的picral溶液蚀刻。

Study of the process of rolling steel balls in skew rolling mill – metallographic analysis
This paper presents the results of metallographic research studies carried out for stock materials as well as the samples collected from the balls formed in the rolling process in a skew rolling mill. The stock material was bearing steel 100Cr6 and the steel from rail scrap. The rolling process was carried out in parallel for the two assumptions: the conventional method (hereinafter referred to as conventional rolling) and the modified method (hereinafter referred to as modified rolling). After the rolling process, three cooling media were used: air, water and oil. The pictures below, which depict microstructures, were taken using the bright-field and the dark-field microscopy technique, the samples were etched with a 4% solution of picral.
