It is found that,under favourable conditions,a rate of carbon removal ofabout 0.015—0.020%C per minute(that of the normal smelting with ore beingaround 0.005% C per minute only)may be obtained;(FeO)and[O]decreasesignificantly and approach to equilibrium with[C]during the oxidizing period,andthe decrement of[O]increases proportionately with the increase of the rate ofcarbon removal.Dephosphorization during the oxidizing period is found to be rather ineffective,the average[P]removed amounts to about 0.004% only.With a supplementaryoperation of dephosphorization during the melting period,[P]can be reduced toless than 0.015% at the end of oxidizing period.However,the dephosphorizationmechanism in the case of the oxygen smelting is still not yet clear. 收稿日期: 1956-03-18      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 方柄 王景唐 胡壮麒 刘成器 邢中枢 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1956/V1/I3/243 [1] #12 [2] #12 [3] #12 [4] #12 [5] Schenk,H.,Physical Chemistry of Steel-making(English edition),1945,148． [6] #12 [7] 高桥俊雄,铁与钢,昭和28年(1953) 2月,97． [8] 同文献[4] ,512-513． No related articles found!
