Laboratoryreduction tests were made with gases having compositions similar to blowing with blastswith or without injection of coke oven gas. The actual data of smelting of the self-fluxing sinters in a blast furnace are used to make necessary corrections for the resultsobtained from the laboratory tests, in order to estimate the possible coke rate of smeltingself-fluxing pellets without injection of coke oven gas in the same furnace. Estimation ofcoke rate is made by solution of two simultaneous equations, one for the coke requiredfor direct reduction of Fe_xO, MnO, P_2O_5 and SiO_2, heat supply and carburization, andthe other for that required for indirect reduction of Fe_xO multiplied by (1+ΔC％), plusthat required for carburization, where ΔC％ is the percentage ratio of the actual cokerate above the theoretical value to that required for indirect reduction of Fe_xO. Esti-mations are made for lowering ΔC in order to decrease the existing coke rate of smeltingof the self-fluxing sinters. The ΔC is considered to be a better measure for the efficiency of blase furnace opera-tion, in comparison with CO/CO_2 and coke rate. 收稿日期: 1965-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 陈大受 赵孟坚 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1965/V8/I3/281 [1] Paschal, F., Himber, F.: Journees Internationales de Siderurgie, (Luxembourg, 1--4 Oct., 1962) , p. 569． [2] Chiyoji, S.: Blast Furnace Steel Plant, 1962, (2) , 136． 堺千代次: 铁钢, 1961, 47, 234． [3] Лазарев, Б.
