我厂有些产品零件,如20鋼襯套,需要渗碳淬火。滲碳采用固体渗碳法,渗碳剂的成分是:木炭末75％,碳酸鈣(电石渣)25％,在950～980℃下进行,渗碳速度平均每小时0.30～0.32公厘。在增产节約运动中,李文进同志建議用泥煤代替木炭,并在实际使用中获得成功。泥煤每公斤0.019元,木炭每公斤0.24元,这样可以节省好多資金。现在我厂已經全部用泥煤作固体渗碳剂,渗碳質量合乎要求。
Some of our product parts, such as 20 steel bushings, require carburizing and quenching. Carburizing solid carburizing method, carburizing agent composition is: charcoal 75%, calcium carbonate (calcium carbide slag) 25%, carried out at 950 ~ 980 ℃, the average carburizing speed of 0.30 to 0.32 mm per hour. In the campaign to increase production and save energy, Comrade Li Wenjin suggested replacing peat with peat and succeeding in actual use. 0.019 yuan per kilogram of peat, 0.24 yuan per kilogram of charcoal, so you can save a lot of money. Now I plant all with peat as a solid carburizing agent, carburizing quality in line with requirements.
