In hot rolling process, reheating furnace and roughing mill are controlled separately in general, and as a subsequent equipment of reheating furnace, roughing mill can not feed useful rolling information back to reheating furnace in time, so that reheating furnace can not heat slabs according to the requirement of roughing mill.

在热轧过程中，加热炉和粗轧机基本上是各自独立控制的，粗轧机作为加热炉的后续设备不能及时地把轧制信息反馈给加热炉，因而导致加热炉不能按照粗轧机的生产要求去完成钢坯的加热过程。
