摘要
将同一炉号的高碳铬轴承钢设计加工成4种不同形状的试样,对其进行磁粉探伤,结果表明:采用多台阶非对称塔形试样,可以更清晰更全面地显示原材料不同层面的带状碳化物,有利于减少废品率。
The high carbon chromium bearing steel from same furnace number is designed and manufactured to samples with four different shapes,and the magnetic particle inspection is carried out.The results show that the banded carbide in different layers of raw materials is displayed clearly and comprehensively by using multi-step asymmetric tower sam-ple,which is helpful to reduce scrap rate.
