9th ECCC European Continuous Casting Conference – ECCC 2017

Depending on the product or the material grade, conventional deburring machines, such as e. g. with rotating hammers are in many cases not capable to reliably or completely remove the burr from the edges and corners of a continuously cast product. Burr, however, is generated at the front and/or tail ends of a slab, bloom or billet as a result of torch cutting. Likewise, traverse grinding of the slab's rolling surfaces can also cause burr at the long side edges of the slab, whereby such burr can even be more difficult to remove. Based on their experience and know how with abrasive machining processes (abrasive cutting, high-pressure grinding) over a period of more than 50 years up to now, BRAUN has developed a highly flexible deburring grinding machine for applications which are too difficult for conventional deburring techniques. BRAUN's deburring grinding machines were successfully introduced to the steel and special metals industries and have proven their worth under normal production conditions already. The subject paper describes the key features and advantages of BRAUN's machine design and the operational results from the first already completed Projects.
