WJ87796 甲醇—煤油滴注式热处理气氛的控制——《工业加热》,1987,vol24,№1,38～47,(日) 中国在本世纪七十年代成功地开发了以甲醇作载气,煤油作富化气的滴注式渗碳工艺和以甲醇作载气,煤油、氨气作工艺气氛的滴注式氰化热处理工艺。本文概述了两种工艺的碳势、氮势控制,指出,甲醇—煤油滴注式气氛与其它有机液体相同,具有良好的可控性与再现性;井式炉、多用炉均无碳黑产生,且处理
WJ87796 Methanol-kerosene drip heat treatment atmosphere control - “Industrial Heating”, 1987, vol24, № 1,38 ~ 47, (Japan) China in the seventies of this century has successfully developed a methanol carrier gas, kerosene As gas-rich drip carburizing process and drip-type cyanidation heat treatment process using methanol as a carrier gas, kerosene and ammonia as process atmosphere. In this paper, the carbon potential and nitrogen potential of the two processes are summarized. It is pointed out that the methanol-kerosene instillation atmosphere is the same as other organic liquids and has good controllability and reproducibility. Both the pit furnace and the multi-purpose furnace have no carbon black generation , And processed
