锋利刀具品种包括学生用刀片、削铅笔刀和伞兵刀等品种。北京锋利刀具厂产品由于热处理工艺不当,废品率相当高。例如:削铅笔小刀淬火开裂的废品率高达30％左右,而且淬火硬度达不到要求;伞兵刀的淬火废品率更高,还经常发生刀尖或柄部断裂。为了提高质量,我热处理交流队应北京锋利刀具厂的要求,从调查原工艺着手,组织技术服务 Sharp knife varieties include student blades, pencil sharpeners and paratroopers and other varieties. Beijing sharp knife factory due to improper heat treatment process, rejection rate is quite high. For example: pencil sharpening knife quenching and cracking rate of up to 30%, and the quenching hardness of less than required; paratrooper quenching rejection rate is higher, but also often tip or handle fracture. In order to improve the quality, I heat exchange team should Beijing sharp knife factory requirements, from the investigation of the original process, organize technical services
