上海职工金相热处理技术协会与山西省河津县津津化工厂于1989年7月7日在上海标准件五厂联合召开了TG-463钢铁发黑剂现场经验交流会,到会代表60多人。上海标准件五厂和上海造纸机械总厂介绍了使用经验。标准件五厂从1988年11月开始用TG-463发黑剂代替传统碱性煮黑工艺,日产各种规格标准件12吨,连续八个月,生产正常,质量稳定。与碱性煮黑相比,TG-463钢铁发黑剂的优点是:(1)成本低;(2)使用现场无有害的酸碱气体,工人劳动条件好;(3)工件表面黑色牢固。
Shanghai Metallurgical Workers’ Association Metallurgical Heat Treatment Technology Association and Tianjin Jinjin Chemical Plant of Hejin County in Shanxi Province jointly held the TG-463 steel blackening agent field experience exchange meeting on July 7, 1989 at the Shanghai No. 5 Standard Factory. More than 60 delegates attended the meeting. Shanghai No. 5 Factory of Standard Parts and Shanghai Paper Machinery General Factory introduced their experience. Standard Parts Factory began to use TG-463 blackening agent in place of traditional alkaline brewing process in November 1988. It produces 12 tons of standard parts of various specifications for eight consecutive months. Production is normal and quality is stable. Compared with alkaline boiled black, the advantages of TG-463 steel blackening agent are: (1) low cost; (2) no harmful acid-alkali gas at the site of use; workers have good working conditions; (3) the black surface of the workpiece is firm.
