Spray coating processing SPRAY PROCESSING
Wear and corrosion-resistant thermal spray coating repair for workpieces such as submerged rolls, guide rolls, furnace bottom rolls, and conveyor rolls in the steel industry.
In the steel industry, numerous equipment components—such as submerged rolls, guide rolls, furnace bottom rolls, and conveyor rolls—are subject to wear, corrosion, and other forms of degradation. These components operate continuously at full capacity under harsh conditions characterized by high temperatures, oxidation, high-temperature corrosion, mechanical wear, and molten-metal erosion, making them highly susceptible to damage. Examples include the severe high-temperature corrosion of converter shell skirts and flues; thermal and cold fatigue in support rolls, guide rolls, and pinch rolls on continuous casting lines; mechanical wear on billet continuous casting line molds, conveyor rolls, and various process rolls; fatigue and wear in tension rolls and straightening rolls on cold-rolling mill lines; high-temperature corrosion and buildup on furnace bottom rolls in continuous annealing furnaces; as well as erosion and wear caused by molten metal on submerged rolls, tension rolls, and guide rolls in continuous hot-dip galvanizing lines. All these issues can be effectively addressed through thermal spraying using high-strength, high-performance materials. The working condition for supersonic (HVOF) flame spraying on roll surfaces: intermetallic wear. Solution: Supersonic spraying with WC/C0. Technical specifications: Coating thickness 70–120 μm; coating surface roughness R3.5–6.5; coating adhesion strength ≥55 MPa. Working condition: Intermetallic friction and wear. Solution: Two-step flame-spraying (welding) induction-coating melting treatment. Spraying material: NiCrBSi (HRc 55–62). Technical specifications: Coating thickness 0.7–1.0 mm; coating surface machinable after grinding. Working condition: High-temperature environment corrosion and metal oxide adhesion. Solution: Explosive spraying of composite ceramic materials or plasma spraying of oxide ceramic materials. Technical specifications: Coating thickness 0.7–1.0 mm; coating surface machinable. Materials, equipment, processes—our solutions: We have accumulated extensive experience in coating applications and are now successfully replicating these proven cases. We will guide you through the entire coating manufacturing transformation process, ensuring: rapid production start-up; a reliable supply solution covering all aspects—from materials and equipment to processes; coating trials conducted either on-site at your facility or at our technical center; and consistently high coating quality and efficiency.

Product Description
Wear and corrosion-resistant thermal spray repair for workpieces such as submerged rolls, guide rolls, furnace bottom rolls, and conveyor rolls in the steel industry.
In the iron and steel industry, numerous equipment components operate continuously at full load under harsh conditions characterized by high temperatures, oxidation, high-temperature corrosion, mechanical wear, and corrosion by molten metals. As a result, these components are highly susceptible to damage—such as high-temperature corrosion of converter shrouds and flues, thermal and cyclic fatigue of support rollers, guide rollers, and pinch rolls in continuous casting production lines, mechanical wear of molds, conveying rollers, and various process rollers in slab continuous casting lines, fatigue and wear of tension rolls and straightening rolls in cold-rolling mill production lines, high-temperature corrosion and scaling on bottom rollers in continuous annealing furnaces, and erosion and wear caused by molten metal on immersion rolls, tension rolls, and guide rolls in continuous hot-dip galvanizing lines. All these failure issues can be effectively addressed by applying thermal spraying techniques using high-strength, high-performance materials.
