Metallurgical Machinery

Key components on metallurgical production lines such as laminar cooling rolls, conveyor rolls, furnace bottom rolls and moulds are continuously subjected to harsh service conditions including high temperature, heavy-load abrasive wear, intense impact and thermal fatigue. Frequent component failures arise from wear and corrosion, bringing high replacement costs and massive production downtime losses.

As an advanced remanufacturing technology, laser cladding features outstanding bonding strength and remarkable performance improvement, serving as a core solution to extend service life and boost production efficiency of metallurgical equipment:

For outer surfaces of roller parts including conveyor rolls, pinch rolls and laminar cooling rolls, laser cladding of high-hardness iron-based or nickel-based alloys is adopted. The resulting layers deliver far superior wear resistance and high-temperature resistance compared with conventional processes, greatly prolonging service life.

For surfaces of components such as continuous casting moulds and guide guards, laser cladding with special alloy materials produces dense coatings with excellent thermal fatigue resistance, which effectively improves the surface quality of continuous casting slabs and overall production efficiency.
