当钢坯被轧制为线材时，钢坯表面的“凹坑”缺陷对线材的表面质量仍有一定的影响。
When it is rolled into wire rod, the pit defect can be seen, affecting the surface quality of wire rod.
将理论计算结果与炉内局部强化加热的供热方法相结合，使钢坯进轧机的温度分布均匀性有明显改善，满足了工艺要求，提高了产品轧制质量。
Using the counting outcome and method of enforce heated in the furnace guide the produce, the temperature distribution is in keeping with hot rolling technology and improves the quality of products.
这个阶段的产品是横断面较小的半成品，如板坯、大钢坯、小方坯等。这些半成品适合于进一步轧制。
In this stage semifinished products with smaller cross sections are produced, such as slab, bloom or billet, which are suitable for further rolling.
