Beijing Guben Guben alloy wire alloy wire specially developed for the spiral welding repair, welding a layer hardness greater than HRC62. Working for screw propulsion (out) when a large resistance conditions, Guben alloy wire with a smooth weld characteristics, and contrast can effectively reduce electrode wear friction reducing wear. In the brick industry, long-term use of vacuum extruder that the use of a spiral electrode wear repair work life of 5-7 days, use coupon alloy wire coil repair work life up to 30 days. Casting wear-resistant screw contrast, use coupon alloy wire has a higher price. Applications: vacuum extruder, vacuum crowded mud machine, vacuum extruder, vacuum pug mill, extrusion molding, screw conveyor, spiral centrifuge, spiral classifier hardness: HRC 62-67 wire diameter: 1.6 mm
