  • Plate Leveler Steel Plantech

    Quality Enhancement The SuPerLeveler™ utilizes the "dynamic crowning method" to control roll gap deviation throughout the entire steel plate something that was not possible with conventional "preset levelers" (a method in which the amount of lateral deflection is set in accordance with the anticipated amount immediately before straightening begins).

  • Identification and optimization for hydraulic roll gap

    Jun 12 2015 · In order to improve the control performance of strip rolling mill theoretical model of the hydraulic gap control (HGC) system was established. HGC system offline identification scheme was designed for a tandem cold strip mill the system model parameters were identified by ARX model and the identified model was verified.

  • Temper millWikipedia

    The heart of the temper mill is the cold rolling mill stand which produces the temper pass. It will include electric powered drive motors and speed reduction gearing suited to the process desired. The design of the rolling mill can be a 2-high or 4-high (even 6-high in some cases). The mill stand can be work roll driven or back up roll driven.
