Study on Heat Transfer Behavior on Broadside Copper Plate of Mold for Thin Slab Continuous Casting

Temperature distributions on CSP mold copper plate of a certain steel mill are measured by a mold temperature monitoring software. A two-dimension model for mold heat flux distributions is built on the basis of casting parameters including real-time copper temperature,original temperature of cooling water,and temperature differences of cooling water. The effect of slab width and casting speed on the heat flux distribution on the meniscus is discussed. The results show that the distributions of heat flux and temperature in mold are nonuniform. The uniformity of the heat flux distribution is increased with the increase of slab width or the decrease of the casting speed.
