固体渗碳剂大多以木炭为主体。但木炭活性小,扩散緩慢,如果渗碳温度控制不当,很难得到预期的效果;同时,木炭价錢貴,消耗量大,目前还不能充分供应。我厂段长杜蔭芝同志針对这种情况进行了研究,在工程师张少武同志协助下,終于研究成功用廉价的煤粉代替木炭做渗碳剂,并取得了很好的效果。渗碳剂的配制經过多次試驗,我們認为:渗碳剂的配合成分以煤粉50％,木屑40％和碳酸盐10％比較适宜。煤粉要用含硫量比較低的无烟煤粉(我們是用平崗煤矿的煤粉),粒度应在2～5公厘;在使
Solid carburizing agent mostly charcoal as the main body. However, charcoal activity is small, diffusion is slow, if the carburizing temperature is not properly controlled, it is difficult to get the desired results; the same time, expensive charcoal, consumption, currently not fully available. Comrade Du Yinyi, director of our factory, conducted a research on this situation. With the assistance of the engineer Zhang Shaowu, he successfully researched the successful use of cheap coal powder instead of charcoal as a carburizing agent and achieved good results. Carburizing agent preparation After several tests, we believe that: carburizing agent with the composition of coal 50%, sawdust 40% and carbonate 10% more appropriate. Pulverized coal to be used with relatively low sulfur content of anthracite coal (we are using coal mine Pinggang), the particle size should be 2 to 5 mm;
