Abstract

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.

斜轧机轧制钢球过程的研究——金相分析
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。
