摘要
本文简述了颗粒模具的服役条件及选材，对高硬度耐磨颗粒模的生产工艺进行了详细研究，由于本产品采用了既节约又先进的渗碳工艺，其产品质量可以和国内外同类产品相媲美．取得了较好的经济效益和社会效益。
This peper deals with the service conditions and the selected materials of the feed-process of the die to get high hardness and high wear-resistant results. Because of the optimal process, the quality of the product can compete with other home-made or external-made ones. Lots of benefit can be realized.
