Flexible Deburring Grinding Solutions For Slabs, Blooms and Billets For Continuous Production

摘要

During the continuous casting process, molten metal is solidified and formed into slabs, blooms or billets for subsequent rolling in the finishing mills. Since the 1950's, it has evolved into the most frequently used casting process for steel (in terms of tonnage). Its advantages are an improved yield, a reliable quality, a high productivity and an excellent cost efficiency. Continuous casting produces metal sections at lower costs with better quality, due to its inherently lower costs.At the end of the continuous casting process, it is required to shorten the cast products or to carry out a secondary cutting for the next production steps whereby the cutting is performed by mechanical or thermal methods.Continuous cast products must be cut to length for the next production steps using mechanical or thermal methods. The mostcommon method is torch cutting, which leaves slag deposits, known as burrs or beards, on the upper and, in particular, the lower edge of the cut end. This burr (or beard) must be removed before the downstream rolling process in order to prevent considerable damage to the rolls and to avoid rolled-in defects.Conventional deburring methods, e.g., rotating hammers or shear knives, do not reliably remove the burr reliably from the front and tail ends of the product. BRAUN Maschinenfabrik has therefore developed a highly flexible deburr-grinding solution (patent pending). Based on BRAUN's proven HP high-pressure/high-performance) grinding technology, this solution provides rapid and reliable deburring.Traverse surface grinding of slab rolling surfaces by certain types of slab grinding machines can also leave burrs at the longitudinal slab edges. Such burrs can be particularly difficult to remove. BRAUN's automated deburr-grinder offers a reliable, practically proven solution for that task.
