Study on Heat Transfer Behavior on Broadside Copper Plate of Mold for Thin Slab Continuous Casting
-
摘要: 使用温度监测软件,在线采集了某钢厂CSP结晶器铜板实际生产过程中温度数据。根据铜板实测温度、冷却水量、入水温度及水温差等参数,利用传热模型建立结晶器热流的二维分布模型,并讨论坯宽与拉速对弯月面处热流密度分布的影响。计算结果表明:结晶器热流和温度在横向分布不均匀,坯宽越宽弯月面处热流密度分布越均匀,拉速越大弯月面处热流密度分布越不均匀。Abstract: 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.
