【摘要】 采用数值模拟的方法,基于速度边界层理论和力的平衡原理,建立描述夹杂物在结晶器内运动的数学模型。以梅钢板坯连铸结晶器断面220mm×900mm、拉速1.2～1.8m/min等条件为研究对象。研究水口倾角、水口插入深度、拉坯速度对结晶器内钢液夹杂物行为的影响。得出有利于生产的设计数据。更多还原

【Abstract】 Adopted numerical simulation method, based on the speed of the boundary layer theory and the balance of power theory, the mathematical model of inclusions movement in the mold is established. Take the section 220 mm× 900 mm, speed 1.2 ~ 1.8 m / min, and other conditions of the slab continuous casting mold of Meishan Iron & Steel for the object of study. Study the nozzle angle, nozzle insertion depth, the casting speed of the liquid steel in the mold of the impact of inclusion.The available design data for production is obtained.更多还原
