Abrasive cutting is the ideal cutting technology to increase the throughput capacity as well as the flexibility of hot rolling mills, mainly for long but also for flat products. A higher degree of automation, reduced overall running costs and in particular an improved quality of the rolled products are as well substantial advantages of abrasive cut-off machines compared to conventional cutting techniques. For that reason, new rolling mills, in particular for SBQ products, are equipped with abrasive cut-off machines. During recent years, also numerous existing rolling mills have been upgraded by retrofitting abrasive cut-off machines. To achieve best possible results, however, it is essential that the abrasive cut-off machines used are specifically designed and perfectly tuned to the individual application. Taking large_x0002_scale projects recently executed by BRAUN as examples, the concepts how the requirements of rolling mill equipment and rolled product are met are described.
