Roller press the maintenance of the roll surface
Particle size and hardness of the roller press extrusion of the surface wear of a very big impact. Roller is the roller surface wear mechanisms of the high stress abrasion and roll surface subsurface fatigue wear and overall performance. Roller press roll surface surfacing failure modes and the roll surface properties of the materials and methods Roll former of welding technology, performance materials are crushed, the work pressure roller press operation and the roller press roller body is closely related to material properties. Roller press roll surface for normal wear and tear, excessive wear, peeling off a large area, overload operation, performance and body roll into the foreign body Rollformer leading to damage to various failure modes, Zhengzhou Machinery Research Institute developed using self-ZD series of wires, rods We propose three restoration methods: on-site repair welding, spot welding to restore the size and performance of repair, restoration of size and performance of off-Surfacing.
