| Duroxite Roller Wire is a flux-cored welding wire for roller repair in the cement and power industries using an open-arc welding process. The weld deposit contains abrasion-resistant material which is composed of a high proportion of extremely hard primary M C chromium-rich carbides with a typical hardness of 1700 HK . The carbides are dispersed evenly in a ductile eutectic austenite matrix. Besides a rich chromium content in the wire, additional molybdenum is added to improve overlay toughness, strengthen the matrix, and refine the carbides’ size to increase abrasion resistance and extend service life. The Duroxite Roller Wire is designed for refurbishing worn rollers with stringer bead welding. The wire is suitable for welding on curved surfaces, and it is feasible to deposit multiple layers up to 75mm (3’’) thick. Preheating, interpass temperature, and post weld heat treatment are as needed according to the base metal recommendations. It naturally reveals stress-relief cracks after welding. Key Benefits - Same wear resistance guaranteed from surface through 75% depth of the overlay.
- Optimal alloy formulation that forms a carbide composition which provides a good combination of wear resistance and homogenous bonding.
- Feasible to weld up to 75mm (3’’) thick to rebuild worn rollers with extreme wear back to their original design.
Typical Applications: Duroxite Roller Wire is mainly designed to repair roller wear parts which work at temperatures up to 350ºC (660ºF). Typical examples include cement vertical mill rollers and coal pulverizer rollers.Data provided by SSAB. |
