For remelting a low carbon alloy steel(an electrode of 76 mm in diameter, 3000 A current (rms) and the slag of CaF2+30 mass-% Al2O3+20 mass-% CaO system) with the parameturs selected reasonably,the amplitude magnetude of magnetic field intensity inner the electrode along the formation direction of electrode tip cone is continuously increasing to a maximum value being about 2.6×104 A/ m near the cone top, then decreasing in the slag bath, ingot pool, mushy zone and solid ingot. For a high speed steel(M2) ingot on another unit with a mould of 140 mm in diameter (80 mm diameter electrode and the slag of CaF2+CaO+Al2O3+MgO system), the predicted magnitude and profile of the magnetic field intensity in the slag bath and ingot pool of the system by the model are in pretty good agreement with the practical measurements. This model may be used as a good and reliable basis for the further study on the fluid flow and the heat and mass transfer processes in ESR system .Correspondent: WEI Jihe, professor,(Department of Materials Science and Engineering, Shanghai University,Shanghai 200072) Key words:  electroslag remelting      magnetic field      mathematic simulation      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1995/V31/I14/51 1DilawariAH,SzeleklyJ．MetallTrans,1977;8B:2272DilawariAH,SzeleklyJ．Proc5thIntConfVacMet&ESRProcess,Munich,Leybold-Heraeus,1976:1573DilawariAH,SzeleklyJ．MetaIlTrans,1978;9B:774ChoudbaryM,SzekelyJ．MetallTrans,1980;11B:4395ChoudharyM,SzekelyJ．IronSteelmaking,1981;8:2256魏季和,任永莉．金属学报,1984;30:B4817魏季和,MitchellA．金属学报,1984;20:B2808魏季和,MitchellA．金属学报,1984;20:B2619,196910获野和已,原茂太．铁钢,631977:2141 11刘应书,魏季和,向顺华,任永莉．全国第五届冶金过程动力学和反应工程学学术会议论文集,中国金属学会冶金过程物理化学学会,济南,1991:259 [1] SU Zhenqi, ZHANG Congjiang, YUAN Xiaotan, HU Xingjin, LU Keke, REN Weili, DING Biao, ZHENG Tianxiang, SHEN Zhe, ZHONG Yunbo, WANG Hui, WANG Qiuliang.
