must meet the highest demands, the work roll grinder in the roll shop, too, must fulfill the highest quality standards regarding geometrical accuracy and machining quality. The foundation-free WS 450 S with a Monolith™ machine bed effortlessly meets these requirements. The roll grinder is equipped with a HCC/KPM two-point measuring …
Early detection of roll defects. In order to minimize downtime in hot rolling mills, it is important to identify defect rolls early. This is why HCC/KPM has developed surface inspection technologies that reliably locate cracks and other defects near the surface which cannot be seen with the naked eye.

The Roll Shop Management System (RSMS) by HCC/KPM integrates all roll shop components into a complete information network – from grinding machines to chocks, bearings and grinding wheels. Based on the data collected, the RSMS automatically creates an overview of all registered components and their production cycles.
machines located the roll shop. Within the automatic grinding area, once the loading of a specific roll into a roll grinder is recognised by the Grinder Data Interface (GDI) application, it sends all the rolls required details to the Grinder CNC. After completion of the grinding process the updated status and information is then sent to the RSTS.

reversing rolling mill (shown below) with 750 mm diameter rolls made of tool steel is available for this task. The rolling mill has a power capacity of 5 MW per roll. The rolls rotate at a constant angular speed of 100 rev/min. The steel work material has the following flow curve at the rolling temperature: MPa.
In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.
