X-Pact® TRC® provides fully automatic threading and stable rolling conditions by accurately positioning the strip in the pre‑adjusted roll gap from the first contact. The system reduces off-gauge lengths and operator‑dependent interventions, ensuring smooth direction changes and consistent strip guidance. By incorporating model-based roll gap settings and automatic alignment functions, X-Pact® TRC® improves productivity and yield through minimized non‑productive times and reliable strip handling.

Customer challenges addressed

  • Reduction of off-gauge and off-flatness weight and/or length by up to 50%
  • Yield increase of up to 1.5%
  • Stable rolling from the strip head end to the strip tail end
  • Improved efficiency due to reduced, operator-independent threading times
  • Elimination of waiting times after changing the rolling direction
  • Early tension build-up with minimized roll marks
  • Consistent roll gap positioning via model-based control
