Preset model of bending force for 6-high reversing cold rolling mill

SmartCrown mill, 4-high edge drop and crown compact (ECC) mill, 6-high HC mill, have been developed and applied to the production of cold-rolled strip. Currently, the 6-high reversing cold rolling mill is widely used because of its less investment but effective and powerful ability to control shape. The important controlTherefore, the optimization of the rolling schedule of the single-stand reversing cold rolling mill is mainly the optimization of the load distribution. According to setting the specific optimization objective, the optimal load distribution scheme is obtained by the optimization algorithm, and other rolling technological parameters are then calculated.Optimization of Rolling Schedule for Single-Stand Reversible Cold

Cold Rolling Process Overview Matmatch

The cold rolling mill is usually fitted with thickness gauges that check the steel as it comes out of the rollers. Reversing mills are designed so that the steel can be reversed and pushed back through the rollers which are brought closer together each time until the desired thickness is achieved.Single Stand Six High Cold Reversing Mill for Carbon Steel. With intermediate roll shifting and horizontal roll stabilization, it is designed for high production of wide and thin gauge strip with superior thickness and flatness tolerances.

Modeling and validation of bending force for 6-high tandem cold rolling

As shown in Fig. 3, the UCM 6-high cold rolling mill is based on the ordinary 4-high cold rolling mill with the addition of an intermediate roll that can shift laterally between the work roll and the backup roll.Through the hydraulic roll bending system, applying a variable bending force to the end of the work roll or intermediate roll In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour.

Shape and Gauge Control of Strip in a Cold Rolling Mill

In general in tandem cold rolling mill / two-stand cold reversing mill the stands can be of 4- high type or 6-high type (i.e., stands with 6 rolls). The single stand cold reversing mill process can be achieved (in particular for stainless steel) with stands of 20-high type also known as cluster mill or Sendzimir mill. Strip shape measurement systemIn reversing mills, productivity can be improved by reducing the number of necessary rolling passes to achieve the desired final strip thickness. The first Hyper UCM was successfully installed and started up in a single-stand reversing cold mill at Maanshan Iron and Steel Co. Ltd. (Maanshan Steel) in 2013.The Hyper UCM: Next-Generation Rolling Mill Stand Metals
