描述了武钢冷轧厂罩式退火炉内钢卷的温度分布和渗碳体级别变化规律，分析了不同退火温度条件下的渗碳体形貌和尺寸。结果表明，在罩式退火炉里钢卷外圈保温时间和退火温度均超过了钢卷内圈，钢卷外圈较内圈容易产生超标渗碳体。
The variation of temperature distribution and cementite grade in coil annealing furnace of WISCO cold rolling mill is described. The morphology and size of cementite under different annealing temperature are analyzed. The results show that in the annealing furnace, the holding time and the annealing temperature of the outer coil of the coil exceed the inner coil of the coil, and the outer coil of the coil tends to produce excessive carburizing body than the inner coil.
