Engineering Your Competitive Edge Applications of Kennametal mill rolls

ungsten carbide is a proven material for many stands in the rolling mill industry. Tungsten carbide grades developed by KENNAMETAL EPG achieve considerably longer tool lives and improved surface quality for rolls in comparision to cast iron rolls or other materials. Applications of Kennametal rolls KENNAMETAL EPG tungsten carbide ring grades are characterised by good machinability. To a large extent these tungsten carbides may even be mechanically worked after sintering. Thus the tungsten carbide grades containing binding phase of approx. 15 % may be turned with PCD (polycristalline diamant)...

Throughout the rolls market KENNAMETAL EPG is known for short-term delivery and above all delivery on time. The geometrical precision of ground and polished areas also deserves to be emphasized. KENNAMETAL EPG also offers a remachining service for various applications, especially for polished cold-formed rolls. Besides remachined rolls as much as new rolls satisfy the highest requirements. KENNAMETAL EPG technical engineers and metallurgists are world-wide at your dis- of Kennametal rolls posal to provide advice and solutions.

Manufacturing methods Turning A great number of KENNAMETAL EPG tungsten carbide grades for rolling mill application can be turned with PCD or CBN. However an interrupted cut should be avoided by all means. Nevertheless a machine designed for hard turning of tungsten carbide is a necessary precondition. This kind of processing permits, subsequent to sintering, a low-cost and fast premachining of flat sides, inner diameters and also the net shaping of the grooves. A binding phase content of minimally 15 % together with a maximal hardness of approx. 1200 HV30 represents a rough standard for the...

Warm rolling The warm rolling particularly requires the elevated temperature hardness and dimensional accuracy of tungsten carbide as well as its stability to alternating temperature stress. In this range not just the KENNAMETAL EPG standard MN, FN or RCV roll grades are applicable but also special KENNAMETAL EPG GE-forming grades. Applications of Kennametal rolls KENNAMETAL EPG offers theses rolls as blanks, rolls in a semi-finished state but also finished and ground (also with several grooves) within short delivery terms. Cold-rolling Cold rolls are characterised by pressure resistance in connection...

Special forming rolls or embossing rolls Applications of Kennametal rolls KENNAMETAL EPG is also in the position to manufacture nearly all other forming, embossing or flange rolls up to a blank outside diameter of 620 mm according to your specific requirements, in more than 100 tungsten carbide or cermet grades of longstanding proven quality. Our process engineers and metallurgists are world-wide at your disposal for further fine-tuning to your specific requirements ready to offer multiple solutions to your problems. Please contact your KENNAMETAL EPG sales representant for further information....

Composite Rolls Under the title “Composite Rolls“ , Kennametal EPG offers rolls for warm rolling applications, with a specific clamping mechanism. This mechanism, with the help of hydraulic forces, puts the shaft supporting the rolls in extension, so that , after release, axial forces are applied to the side of the rolls. Consequently, the contact between the components is guaranteed, and the hydraulic sytem can be removed . Applications of Kennametal rolls This clamping system is simple , can be re-used many times , and is universally applicable. It is proven as an economical unit. Kennametal...
