Prior to further processing of semi-finished steel and special alloy products, it must be ensured that the surface of the workpieces is free from scale and flaws. In addition to that, these products also need to be cut and the cut surface needs to be free from heavy burr and surface hardening. For both applications, even for increasingly large product dimensions and regardless if the product to be ground or cut is cold or hot, BRAUN provide a state-of-the-art solution, either with the multifunctional HP (high-pressure/high-performance) grinding machine or with the high-performance abrasive cut-off machine. © 2015 by AIST.

Forged products need to be cut to remove the product ends, to take samples, or to cut the products to length before further processing. Abrasive cutting has proven to be the ideal technology for these operations, irrespective of the type of forge used or the cutting temperature. BRAUN is a supplier of fullyautomated cutting facilities, complete with material transport and aligning systems including product marking machines and cooling beds. In 2010, the first abrasive cut-off machines designed for cutting wheel diameters of up to 2000 mm went on stream, the largest in the world. Source

Prior to further processing of semi-finished steel products, it must be ensured that the surfaces of the workpieces are free from scale, cracks and other material flaws. High-pressure grinding has been proven to be an optimal technology for removing such surface defects. With BRAUN's multi-functional HP high-pressure grinding machine, a highly flexible, state-of-the-art facility was developed that allows a fully-automated bright, edge and flaw grinding of billets, blooms, ingots and other products. Automated grinding of partial surface flaws, however, also requires an accurate detection of the defects. Furthermore, adequate editing of the flaw coordinates, subsequent transmission of these data to the control system of the grinding machine, as well as the capability of the grinding machines to accurately approach the flaw are an imperative. In this context, the thermoinductive crack detection system developed by vatron gmbh poses an ideal technology for inspecting the surface of the workpiece. Moreover, BRAUN and vatron gmbh have jointly developed solutions which allow the implementation of integrated, fully-automated systems for flaw detection and flaw grinding, including product identification, Dost-arindino re-inspection and data management.

Abrasive cutting is the ideal cutting technology for upgrading existing rolling mills, especially for long products. An increased flexibility, a high degree of automation and in particular an improved quality of the cut products are substantial advantages of abrasive cut-off machines. For the production of value-added products, such as SBQ, the utilization of perfectly tuned, state-of-the-art abrasive cut-off machines is essential to achieve the required product quality. As one important part of the modernization and upgrading plan for their existing bar mill in Chonburi, Thailand, NTS-TATA therefore decided to install a high-performance abrasive cut-off machine from BRAUN in addition to the existing cold shear. By this means, NTS-TATA does have perfect flexibility for rolling both SBQ products and deformed bars. The paper describes how the various challenges of this project were successfully managed and the operational results achieved. Source
