IMS Measuring Systems in Cold Rolling Mills / Processing Lines

Aerospace technology, automotive and shipbuilding, architecture, medical technology, and household appliances - the areas of application for high-quality strip steels seem almost unlimited. The steel industry is developing rapidly and the demands for new, adapted products are also occurring at ever shorter intervals. The economy demands new processes and materials in the steel industry and the demand for the quality of the end product is also subject to a continuous increase. Cold-rolled strip is becoming increasingly important in this context. In order to provide the processing industry with optimum base materials, the rolling processes are complex. Throughout the entire process and its fully automated control for end products of the highest quality, measuring systems from IMS guarantee compliance with minimum tolerances. - Conventional cold rolling mills - Coupled pickling / tandem mills (PLTCM) - Finishing lines - Process lines - Shear lines benefit from our perfectly coordinated highly precise and fully automated measuring technology for the exact determination of: - Thickness - Thickness profile - Thickness edge profile - width - holes - Fine holes - Edge cracks - phase content - internal inclusions / shell defects - coating overlays - flatness - flatness - 2D surface inspection - strip tension / web tension - Speed of web - Length Precisely reproducible measurements as well as real-time evaluations optimize your production facilities and increase product quality while reducing production costs and reject rates. In addition to their longevity and impressive performance, our measuring systems also impress with the extremely convenient user-friendliness of their control and regulation software. The MEVIweb user software developed in-house by IMS convinced the juries of two renowned awards and was honored with the iF Design Award and the Red Dot Design Award.

MEASURING TECHNOLOGY FOR COLD ROLLING MILLS / PROCESSING LINES Measuring Technology in the Steel Industry DEVELOPMENT FOR COLD ROLLING MILLS / PROCESSING LINES Development of new Measuring Systems Continuity at IMS Users expect not only excellent processing properties and usage characteristics, but also high lifetime, longterm value and high quality from modern materials. Only technically superior products – steel of the highest precision – can survive competition on the market. Thanks to constant improvements in strength and deformability, steel can be produced in ever thinner dimensions. And that with ever tighter dimensional tolerances. The finishing coatings on steel are also growing thinner and more effective with ever more complex layer structures. The material behaviour and mechanical dimensions are virtually constant along the complete length and width of a rolled steel strip. To meet these high demands, the steel industry needs innovative, high-precision online measuring technologies with intelligent quality management and analysis systems. The measuring processes and technologies described in this brochure are, together with optimised process models, precision control loops and appropriate regulating elements, the prime prerequisites for achieving the high level of product quality required from high-speed continuous production processes. Maximum availability and reproducible measuring results ensure the high process stability required for continuous operation. IMS works tirelessly developing measuring systems for the improve ment of thickness, profile, width and flatness in rolling mills. In parallel with technical devel opments for equipment improvement such as: • hydraulic adjustment • fast work roll bending systems • slide rolls in conjunction with mathematical models for roll force, profile and flatness IMS measuring systems also undergo continuous optimisation in terms of accuracy, resolution and dynamic performance. Output and profitability in the production of black plate, tin plate and stainless steel depend on, among other factors, compliance with the tolerances prescribed for thickness, thickness profile, width and flatness. Today IMS offers multifunctional measuring systems for continuous measurement of the following quality criteria in cold strip mills: • thickness • thickness profile • thickness edge profile • width • holes • pinholes • edge cracks • phase content • internal inclusions / shell defects • coat layers • flatness • evenness The ideal is a product with constant thickness and width, and a constant prescribed profile along the complete length of the coil – a product without flatness errors and with minimised residual stresses. • 2D surface inspection • strip tension / web tension • speed • length 6 7
