冷顶锻用38CrMoAlA钢丝的试制

Development of 38CrMoAlA Steel Wire for Cold-heading

冷顶锻用３８ＣｒＭｏＡｌＡ钢丝试制过程中，通过多次试验制定出了盘条的球化退火工艺，中间退火工艺，去除氧化皮的方法，以及为减小脱碳层深度，改善表面质量而采取的措施。实验表明：这些工艺和方法解决了试制中遇到的难题，用户对试制的产品满意。

In the process of trial producing 38CrMoAlA steel wire,the spheroidal annealing and middle annealing technologies for wire rod,methods for removing oxide of wire rod and the measures for reducing decarburized depth and improving surface quality of steel wire are laid down through many experiments Practices indicate that these technologies and methods solve the difficult problems Consumers all express satisfaction with the products
