码: A Behavior of meniscus in soft-contact electromagnetic continuous casting (EMCC) rectangular mold ZHANG Lin-tao, DENG An-yuan, ZHANG Xing-wu,WANG En-gang, HE Ji-cheng (Key Laboratory of Electromagnetic Processing of Materials,Ministry of Education, Northeastern University, Shenyang 110004, China) Abstract: According to different technological parameters, meniscus shapes were......
Trans. Nonferrous Met. Soc. China 30(2020) 3124-3232 Transport phenomena in meniscus region of horizontal single belt casting Mian-guang XU1, Roderick GUTHRIE2, Mihaiela ISAC2 1. School of Mechanical... were carried out on the pilot-scale caster for validation. The results show that the meniscus turbulence neither comes from the tundish region, nor from the impingement between the melt and the moving......
圆坯钢电磁软接触连铸的实验研究邓安元1,许秀杰1,王恩刚1,张林涛1,张兴武1,赫冀成1(1.辽宁省沈阳市东北大学材料电磁过程研究教育部重点实验室)摘 要:为确定工业实验基本参数,对电磁软接触连铸结晶器进行了优化设计计算,设计制作了φ100 mm圆坯电磁软接触连铸结晶器,利用Sn-Pb-Bi合金实验研究了结晶器内的弯月面行为,并进行了w(C)为0.22%钢坯的电磁软接触连铸实验.结果表明,电磁软接触连铸结晶器内磁场和弯月面变形具有不均匀性,切缝数为12时,磁场周向分布和弯月面变形较均匀.输入功率增加,弯月面高度......
of meniscus with alternating magnetic field in mold DENG An-yuan, XU Yong-yi, WANG En-gang, ZHANG Xing-wu, HE Ji-cheng (Key Laboratory of Electromagnetic Processing of Materials , Ministry... with alternating magnetic field was investigated. The results show that the meniscus becomes camber due to alternating electromagnetic field, and the free surface is keeping fluctuating. There are two......

nozzle (SEN) for optimizing the flow and temperature patterns in a mold. The effect of SEN design on the mould level stability, meniscus steel flow velocity, and heat transfer of the mold of a medium thin... level fluctuation and a lower meniscus steel flow velocity; proper powder consumption without slag bears due to a reasonable liquid powder thickness. The argon flow rate can be reduced and the mold......
-continuous casting process of 7075 aluminum alloy ingots reduces the thickness of the surface segregation layer,increases the height of the melt meniscus,enhances the surface quality of the ingot......
