Resumo

Surface quality requirements for hot rolled steel sheet have continued to become more stringent in recent years. This sheet quality focus has developed in parallel with corresponding demands for increased productivity and reduced costs at the mill. Although not a panacea, roll gap lubrication systems have been receiving increased attention in support of these objectives. Specifically, roll gap lubrication systems are used in combination with work roll cooling systems and anti-peeling systems to: - Reduce rolling loads and thereby reduce potential for chatter 
-  Reduce rolling torques, and associated energy requirements 
- Reduce potential for rolled in scale by reducing work roll peeling 
- Extend work roll campaign length by reducing peeling (and potentially wear) 
 This paper will discuss how roll gap lubrication, work roll cooling, and anti-peeling systems can be utilized in a coordinated manner to reduce the potential for chatter and peeling, thus enhancing strip surface quality, improving mill productivity, and reducing operating costs.
