拉速(【技】单位时间内连铸机的每一流拉出的铸坯长度。拉坯速度简称拉速。 • Powder consumption decreases gradually until a casting speed of 5m/min, and gradually approaches the fixed value when the casting speed is over 5m/min. 保护渣用量逐渐降低,直到拉坯速度到达5 m/min 为止;拉坯速度超过5 m/min 后,保护渣用量逐渐趋近固定值。)
临界拉坯速度(Further simulations were performed by them to predict this critical casting speed as a function of section size and working mold length (distance from meniscus to mold exit). 为了预测作为断面尺寸和结晶器工作长度(金属弯月面至结晶器出口的距离)函数的临界拉坯速度,他们进行了进一步的模拟。)
