GCr15轴承钢棒线材的球化退火

结合国内外相关的研究和实际生产经验，探讨了GCr15轴承钢的球化机制和退火工艺。从退火质量稳定性角度出发，分析了GCr15轴承钢的3种主要球化退火方式。阐述了退火装备的进步对轴承钢球化退火质量提高的影响，提出了进一步改善轴承钢棒线材球化退火质量的措施。

Spheroidizing Annealing for Bar and Wire of GCr15 Bearing Steel

The spheroidizing mechanism and spheroidizing process for GCr15 bearing steel were discussed in the light of the correlative research at home and abroad as well as the production practice. With the view of stabilizing spheroidizing quality, three essential manners of spheroidizing were roidizing equipment was stated on the improvement on spheroidizing analyzed. The effect of the progress of sphequality of bearing steel. The measures for further improvement on the spheroidizing quality were put forward for both bar and wire of bearing steel.
