welding-alloys.com 8 Solutions for secondary cooling nozzles We supply high-quality air mist and wateronly secondary cooling nozzles, along with a comprehensive refurbishment service for used nozzles to return them to optimal performance. Used nozzles undergo a thorough, nonaggressive cleaning process. Each nozzle is then carefully inspected for spray pattern accuracy and overall condition. Any units that fall outside specification are rejected to ensure consistent performance and reliability. Serviceable nozzles are treated with a specialised coating designed to reduce wear and minimise the risk of blockage. New nozzles are also available with the same advanced coating for enhanced durability. Solutions for rolling and finishing rolls Rolling and finishing rolls are used to reduce and shape steel after casting, from roughing through to final sizing. This includes work rolls and backup rolls in flat product mills and grooved rolls for long products and sections. These rolls operate under high contact stresses and cyclic loading so wear, rolling contact fatigue (spalling) and loss of profile or groove geometry are common. Using our hardfacing and cladding cored wires and automated welding equipment, we rebuild worn surfaces to restore geometry, maintain dimensional control and achieve the required surface finish. All coated nozzles are delivered back to site ready for immediate installation, helping to reduce downtime and maintain efficient operation. Performance in service Consistent spray performance supports stable secondary cooling and strand integrity, reducing the risk of undercooling and unplanned downtime. Refurbishment extends nozzle service life and supports more predictable maintenance planning. Performance in service Where roll bodies and journals remain within repairable limits, refurbishment is typically faster and more cost-effective than purchasing new rolls. This supports higher mill availability through planned roll changes and reduces the risk of unplanned downtime. Repaired rolls provide stable dimensions throughout their service life, ensuring consistent product quality and extended operating performance.
