March 1960, the Secretary for the successful development of a charcoal powder as the main raw materials of "603" drug-free carburizing agent for liquid carburizing, a domestic initiative and promote the use of the country, replacing imported products. 1978, the Division I-IF heat treatment of geological drilling results, the General Assembly by the National Science and Technology Award. November 1983, held in Shanghai in the third international material, heat treatment, when there are several hundred Chinese and foreign experts to the Division I visited. 1986, I was the Secretary for the first heat treatment in the production license. 1987, Secretary of precision gear chemical heat treatment projects, scientific and technological progress in the third place. 1989, I was named Division II national enterprises, is the same industry in the first. 1990, the multi-sensor film coating mouth heat treatment results in the revitalization of the first prize.

1960年3月，我司研制成功了以木炭粉为主要原料的&603&无毒渗碳剂，用于液体渗碳，属国内首创并在全国推广应用，取代进口产品。1978年，我司的地质钻管中频热处理成果，获全国科技大会奖。1983年11月，在上海召开的第三届国际材料热处理年会时，有几百名中外专家到我司参观。1986年，我司获市首批热处理生产许可证。1987年，我司的精密齿轮化学热处理项目，获市科技进步三等奖。1989年，我司被评为国家二级企业，是全国同行业中的第一家。1990年，感应胶片的多层涂布嘴热处理成果获市振兴一等奖。

Two separate tempering treatments at 670 ℃ is the most effective way to eliminate residual austenite in the carburized layer of steel.
