narrow mold(For narrow mold, once inclusions enter the lower flow zone created by the effect of the jet striking the narrow face, it is unlikely that they would rise by buoyancy to the free surface. 对于窄结晶器而言，只要夹杂物一进人流股撞击结晶器窄面效应而形成的下部流动区，它就不可能依靠浮力再上升到钢水自由面。)
narrow face of mold(Care is especially needed in designing the cooling water slots on the narrow face of mold to ensure that they extend close enough to the narrow face edge. 在设计结晶器窄面冷却水缝时需要格外注意，以确保这些水缝足够延伸到窄面的边缘处。)
