Development of Modern Hot Strip mill and its Main Features

Fig 4 Mandrel type and mandrel less coil box. Automatic width control – In general, the width performance of the hot strip is evaluated using two metrics namely (i) average body width deviation, and (ii) width variability at the coil ends. As the control of in-body width improves, the over-width amount can be reduced without the risk of being under-width.

Billet Rolling Mill

For the production of raw material 130 mm x 130 mm to 160 mm x 160 mm, a billet rolling mill works in direct connection with the CC3 continuous casting system.With this plant configuration, we are able to reduce the material throughput time to 4 hours.. By shortening the heating times or deformation without heat loss a large amount of energy is saved.

Strip shape modeling and its setup strategy in hot strip

Shape setup model (SSM) plays a critical role to achieve satisfactory precision of strip shape in hot strip mill process (HSMP). However, for the design of shape model, the lack of systematic shape theory restricts the high accuracy of strip shape. In this paper, the procedure of SSM will be generally introduced and practically demonstrated with a real HSMP producing …
