metallurgical length(【技】连铸坯在正常浇注速度下完全凝固的长度,即从结晶器内钢水面起到铸坯内部液相完全凝固的距离。它与铸坯厚度、钢种、拉坯速度和凝固系数有关。: The 15.7 meter machine metallurgical length allows a maximum cast speed of 6 meters per minute, but other factors such as mold level control, mold design, and mold operating practices are critical in achieving high cast speeds. 铸机冶金长度 15.7m, 可使拉坯速度最高达6 m/min, 但是其他因素,例如结晶器液面控制、结晶器构造、结晶器操作实践等,却成为提高拉坯速度的关键。)
mixed chemistry region length(【技】异钢种连浇时,前后两炉不同钢种的钢水相混而浇铸成的兼有不同钢种化学成分的铸坯区段。: Experiments are conducted using a two-strand continuous slab caster to determine the mixed chemistry region length at low and high casting speeds. 为了确定在低拉坯速度和高拉坯速度下化学成分混合区的长度,利用一台双流板坯连续铸钢机进行了试验。)
