通过实验和数值模拟研究了软接触结晶器电磁连铸传热凝固特点．测定了金属Sn在连铸中的温度场、初始凝固点和坯壳厚度，得到了电磁场影响它们的基本规律.在数学模型中考虑了高频电磁场对金属传热凝固的以下影响：（1）对结晶器壁的感应加热；（2）对金属的加热；（3）电磁力推斥液体金属，减少金属与结晶器壁接触的影响，结果表明，在电磁场的作用下，液相区内的金属温度趋于均匀，初始凝固点位置降低，初生坯壳厚度变薄，铸坯表面质量明显改善；在连铸Sn中，电磁场加热结晶器壁和电磁力减少金属与结晶器壁的接触，增加界面热阻，对连铸传热和凝固的影响，比电磁场加热金属的影响更明显
The characteristics of heat transfer and solidification in soft contact mold by electromagnetic continuous casting were studied by experiments and numerical simulation. The temperature field, the initial solidification point and the shell thickness of metal Sn in continuous casting were measured, and the basic rules of electromagnetic field influencing them were obtained.In the mathematical model, the following effects of electromagnetic field on metal heat transfer and solidification were considered: (1) (2) the metal heating; (3) the electromagnetic force repel liquid metal to reduce the metal and the mold wall contact the results show that the role of the electromagnetic field, the liquid region of the metal In the continuous casting Sn, the electromagnetic field heats the mold wall and the electromagnetic force to reduce the contact between the metal and the mold wall to increase the interfacial heat Resistance, the impact of continuous casting heat transfer and solidification, the impact of electromagnetic heating metal than the more obvious
