ULTRASONIC SEPARATION OF MICRO-SIZED INCLUSIONSIN MOLTEN METAL X.Q.Bai1,J.C.He1 (1.Key Laboratory of National Education Ministry for Electromagnetic Processing of Materials, NortheasternUniversity, Shenyang 110004, China) Abstract:The coagulation time and position of micro-sized non-metallic inclusions in molten metal during ultrasonic separation process were investigated, and the motion......
:The flowing process of filtered and unfiltered molten metal was investigated through hydraulic simulation. The equations for pressure loss was established according to hydraulics and mathematic deduction. The pressure loss model obtained can be used to predict the flow velocity and filling time of molten metal, and also can be used as a guidance when adapting ceramic filters for a casting system......

Preparation of Y2O3?Eu3+ phosphor by molten salt assisted method HUANG Yan(黄 燕)1, 2, 3, YE Hong-qi(叶红齐)1, ZHUANG Wei-dong(庄卫东)2, HU Yun-sheng(胡运生)2, ZHAO Chun-lei(赵春雷)2, LI Cui(李 萃)2, GUO Song...; Abstract: A kind of fine and quasi-spherical Y2O3?Eu3+ phosphor was prepared by firing a preparative precursor at 1 200 ℃ for 2 h with the molten salts of Na2CO3, S and NaCl. The precursor......
as an inert reaction medium [16, 17]. Our group has long focused on the low-temperature smelting of stibnite (Sb2S3) using a molten salt sulfur-fixing process. Sb2S3 is reduced to Sb metal... ZnO. As shown in the schematic diagram in Fig. 1, sulfur was fixed by ZnO in the form of ZnS and also settled at the bottom of the melt, but on top of the molten metal. This process has considerable......
