摘　　要：以兰州钢厂薄板坯连铸机为原型，采用信噪比正交实验设计的方法，通过流场显示、波高测量及冲击力测量，研究了高拉速条件下，浸入式水口的出口角度、出口面积和插入深度对结晶器内流场变化的影响及变化规律．试验结果表明：出口面积比为1．3，出口角度向下倾斜5°，浸入深度为280mm，可以满足提高技速后生产的需要．In accordance with the thin-slab caster mould of Lanzhou I&S Co., the effects of structure, immersion depth, outlet angle and shape on the fluid flow in mould by visualizing the fluid flow and measuring the wave amplitude and impetus under high speed casting have been studied. The results can provide theoretical foundation for choosing reasonable structure of SEN.
