Main speed regulation process of hot strip mill

The speed regulation of hot tandem mill is mainly based on the principle of equal flow per second. However, due to the different design concepts of the main control program, the specific speed regulation process is also different. In order to stabilize the passing steel, according to the principle of equal flow per second, micro-tension rolling can be appropriately adopted between stands, because the distance between stands is short, and it is difficult to adjust the steel once it is piled up; Micro-pile compaction can be properly used between units, because the distance between units is long, even if the steel pile is serious, it can be adjusted quickly. Secondly, the tension control should be judged by combining the fabric type and the temperature of the rolled piece. Tension can be judged by load monitoring and current monitoring.
