Wisco orders coilbox from SMS group


Wuhan, China, 09. Jan 2025

Wuhan Iron & Steel Co., Ltd. (Wisco) has placed an order with SMS group for the strategic investment of upgrading its 1,580 mm hot strip mill in Wuhan, China. The order includes engineering and supply of the complete finishing mill entry area and features an advanced guiding concept with SMS X-Roll® Guide technology as well as a Coilbox in innovative design.

Summary

  • X-Roll® Guides for safe guiding and centering of the transfer bar
  • Coilbox enhances tail-end strip temperature and ensures better temperature homogeneity especially for silicon grades

The project covers three new roller tables with a total of four X-Roll® Guides, which will be installed alongside the new coilbox to ensure safe guiding and centering of the transfer bar. The interacting side guides will be positioned in front of the relocated edge heater, the new coilbox and the existing crop shear and will provide best conditions to feed the strip into the finishing mill.

The project represents a crucial milestone in Wisco's silicon steel strategy. The implementation of the coilbox, particularly for rolling of silicon grades, enhances the tail-end strip temperature and ensures better temperature homogeneity along the entire transfer bar length. This improvement reduces the tail-end rolling force in the finishing mill stands and positively contributes to overall rolling stability.

In addition to the mechanical equipment, SMS will supply a full scope of electrical and automation solution which includes motors, drives and X-Pact® automation systems. The combined application of automation and mechanical equipment from one source by SMS is providing advanced process control as well as technology for the coilbox. 

Wisco decided for the full wrap SMS solution including equipment, automation and process technology to gain maximum benefit. The comprehensive coilbox solution by SMS generates new growth opportunities for the production of silicon steel grades.
