Pinch Rolls plays significant role in plate production process at Size reduction 5-6 Hi Mill with work rolls and at Colier unit -Subjected to hi pressure ,hi temperature and severe friction as it stretches the plate while colling operation takes place -need special alloys formulation to repair and restor it’s wear out position -TNA specializes in this reconditioning process and has repaired few Pinch Rolls for JSW India and provided 800,000 MT of rolled material.
Tarek Nasser Al Akeel Co. (TNA) employs various advanced welding techniques for pinch roll cladding, including:
Submerged Arc Welding (SAW)
Submerged Arc Welding (SAW) is known for its ability to create thick cladding layers efficiently. It provides deep penetration and high deposition rates. Additionally, SAW minimizes spatter, resulting in a smooth finish of the roll’s surface.
Flux-Cored Arc Welding (FCAW)
Flux-Cored Arc Welding (FCAW) is effective in situations where high deposition rates are necessary. This technique offers excellent mechanical properties and is particularly useful in environments that experience high abrasion.
The weld cladding process at TNA is systematic and thorough:
Initial Inspection: A detailed inspection is done on each pinch roll to assess wear patterns, surface defects, and overall condition.
Surface Preparation: The roll surface is cleaned and ground to remove any rust, scale, or fatigue areas, to prepare the surface for better bonding with the weld material.
Cladding Application: Suitable welding techniques are employed to apply the cladding material, to the specific wear conditions and operational requirements of the pinch rolls.
Post-Weld Treatment: After cladding, rolls may undergo heat treatment to relieve residual stresses and enhance the properties of the cladding layer.
Final Inspection and Machining: The clad rolls are inspected for quality assurance. Any corrective measures to be taken are taken.
Extended Service Life: TNA’s advanced cladding techniques can significantly increase the lifespan of pinch rolls.
Enhanced Performance: The application of high-performance cladding materials improves the rolls’ resistance to wear and tear.
Comprehensive Solutions: TNA provides a complete package, including inspection, cladding, machining, and post-weld treatments, ensuring that all aspects of pinch roll maintenance are covered.
Expertise and Innovation: With a team of skilled technicians and access to the latest welding technologies, TNA is committed to delivering high-quality services that meet the specific needs of the industries.
Weld cladding for pinch rolls is an important maintenance practice that significantly enhances the durability and performance of these essential components in steel plants.
