Our reliable and precise X-Shape flatness measurement with measuring rollers of the latest generation meets all requirements of high quality production.
For quality inspection and as an input variable for the flatness control system our measuring system determines the current flatness, taking into account strip tension and rolling speed.
Over 10 years ago, we at SMS group decided to develop and manufacture the most modern flatness measuring rollers ourselves. Highly sensitive sensors detect even minimum variations in strip tension across the strip width by measuring the vertical force components of the strip tension. The strip tension distribution is the measure for the product flatness.
The axial bores have the advantage that the roller shells remain fully intact during manufacturing so that later, during operation, no marks occur on the strip surface. The roller surfaces can be standard-hardened or provided with various coatings, such as chrome or tungsten-carbide. In this way, the rollers' service life is extended, making them more wear-resistant.
Our flexible and integrated flatness control concept provides various technological solutions to minimize the flatness deviation (socalled orthogonal functions, actuator functions). The standardized communication concept enables simple integration even with an existing automation solution.
With X-Shape flatness measurement and control we offer a complete system perfectly tailored to match the process requirements. As part of the X-Pact® electrical and automation systems product family this technology sustainably ensures and even improves the productivity and product quality of the plants of our customers.
Our technological control is designed to ensure strip flatness even under the most adverse conditions and at high rolling speeds of up to 3,000 m/min within narrow tolerances and across the entire strip width.
