采用定量金相法测定了连铸板坯（１８０ｍｍ×１０００ｍｍ）的溶质分布，应用水力学模型方法测定了板坯连铸结晶器内流场结构及流速，运用流体力学、溶质分配理论建立了凝固过程中溶质偏析模型。对铸坯宏观偏析进行了解析
The solute distribution of continuous casting slab (180mm × 1000mm) was determined by quantitative metallographic method. The flow field structure and flow rate in slab continuous casting mold were measured by hydraulic model method. The fluid mechanics and solute distribution theory were used to establish the solidification process Solute segregation model. Macro-segregation of slab was analyzed
