It seems that the graphitization degree is not influential to △H of the carbon blocks in the range of the experimental temperature. The temperature dependence of the A△ is expressed as follows:△H=-33.31+1.11T+3.69×10~(-4)T~2+9.85×10~2Ta~(-1) By differential the temperature dependence of the massic heat capacity c_p is repesented as follows:c_P=1.11+7.38×10~(-4)-9.85×10~2T~(-2) Key words： self-baking carbon block    enthalpy    massic heat capacity    calorimeter 收稿日期: 1996-06-18      基金资助:冶金工业部科技司资助 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 薛向欣 车荫昌 杜英敏 黄晓煜 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1996/V32/I6/669 1郝运中,陈前婉．炼铁,1994:13(增刊):72HaoYZ,ChenQW．ChinRefract,1994;1:93张殿友,肖亦芹,郝运中,陈前婉．炼铁,1994;13(增刊):284CarslowHS．JaegerJC．ConductionHeatinSolids,London:OxfordPress,1959:1015薛向欣,段培宁,黄晓煜,张殿有．中国科协第二届青年学术年会卫星会议辽宁省第二届青年学术会议论文集,工科分册,大连:大连理工大学出版社,1995:906姚广春．冶金炭素材料性能及工艺．北京:冶金工业出版社,1992:1997中国金属学会,中国有色金属学会编．金属材料物理性能手册(第一册)．北京:冶金工业出版社,1987:2728重见彰利．制铁东京:地人书馆,1979:163 [1] 孙俊生; 武传松; 高进强 . 熔滴热焓量分布模式对熔池流场的影响[J]. 金属学报, 1999, 35(9): 964-970 .
