分析了造成板坯沿宽度方向上加热温度不均匀的原因,根据生产实际情况提出了改进措施并付诸实践,验证了改进后板坯沿宽度方向上温度均匀性的改善。 The reasons for the uneven heating temperature of the slab in the width direction were analyzed. Based on the actual situation of the slab, the improvement measures were put forward and put into practice. The improvement of the temperature uniformity in the width direction of the slab was verified.
