分析了热连轧机组精轧机的穿带、加速、稳速、减速等各个阶段的速度制度要求,并在此基础上提出了各个速度段的速度设定方法。精轧机位于热连轧生产线热卷箱和卷取机中间的关键工艺设备,生产中既要与热卷箱形成连开连轧,又要与卷取机形成连轧连卷。合理的设定精轧机每个机架各个阶段的速度,对稳定生产和提高产品质量及产能至关重要。
The requirements of the speed system of the finishing mill in the hot strip mill, such as the threading, acceleration, steady speed and deceleration, are analyzed. Based on this, the speed setting method of each speed section is put forward. Finishing mill is located in the hot-rolling production line between the hot-rolled coil and coiler middle of the key process equipment, both in the production and the formation of hot-rolled continuous open roller, but also with the coiler to form a continuous rolling with coil. Reasonably setting the speed of each stage of the finishing mill for each stage is crucial for the stable production and improvement of product quality and capacity.
