EXPERIMENTAL RESEARCH AND NUMERICAL SIMULATION OF MOLD TEMPERATURE FIELD IN CONTINUOUS CASTING OF STEEL X.S. Zheng1,J.Z. Jin1,M.H. Sha2 (1.Research Center of Foundry Engineering, Dalian University... casting machine. Heat transfer and solidification in a watercooled mold are the most important factors during the continuous casting of steel. For studying the temperature distribution of a mold wall......
Improvement of machining quality of copper-plated roll mold by controlling temperature variation Tae-Jin JE 1, Eun-Chae JEON 1, Sang-Cheon PARK 1, Doo-Sun CHOI 1, Kyung-Hyun WHANG 1, Myung-Chang... machining large roll mold whose machined length was 1 200 mm. The temperature of machining system was elevated during machining roll mold, and this elevation induced thermal expansion of the system......

of the temperature leads to the increase of viscosity. Viscosity curve shows that RE oxide is soluble in some extent in mold fluxes. When RE oxide is in a state of supersaturation, the existence of insoluble... and BaO. However, the contents of Li2O, B2O3, and BaO should be controlled to suitable levels. (4) The solidification temperature of mold fluxes can be increased by the addition of RE oxide, which......
, due to the limitation of the high temperature resistance of metal mold, the metal mold cannot be preheated to the same high temperature as micro-investment precision casting during filling mold...
