X-Pact^® Camber Free Rolling

Challenges

• Thickness wedges and asymmetric heating in the slab may form cambers

Solution

• Effective interplay between the heavy side guides in front and behind the Roughing Mill and the control system for camber and wedge free rolling

Technical advantages

• Cost saving – due to increased yield
• Improved strip geometry - Camber and wedge reduced to a minimum
• Improved process stability / reduced amount of cobbles in the FM due to better strip guidance

Productivity

• Improved process stability and reduced cobbles in the Finishing Mill due to better strip guidance
• Increased yield by 0.5 - 3 %
