"At the end of the continuous casting process, the cast products, such as e. g. slabs, need to be cut to shorter lengths which is mostly done by torches. Torch cutting, however, leaves slag deposits, known as burr or beard, on the edges of the cut product ends. Removal of such burr is essential to avoid defects of the rolledproduct and damages to the rolls. Conventional deburring methods, e. g. by means of rotating hammers or shear knives, do not reliably remove the burr from the head and tail ends of the torch-cut product. BRAUN Maschinenfabrik has therefore developed a highly flexible deburring grinding solution (patent pending). Based on BRAUN’s well-proven HP (high-pressure/high- performance) grinding technology, the newly designed deburring grinding machines are able to rapidly, reliably and economically remove burr from both the upper and lower edges at the ends of the cut products. If necessary, the cut surfaces and also the end zones of the top and bottom surfacesof the cut product can be ground as well. Moreover, BRAUN’s novel-type deburring grinding machines also allows deburring grinding of the longitudinal slab edges (required after traverse grinding of the rolling surfaces of the slab by certain types of slab grinding machines) or deburring grinding of the edges at the ends of round ingots.The machines can be retrofitted to existing production lines and operate in- or offline.
