On a continuous rolling mill fixed speed ratio must be achieved to get stable mass flow Interaction between upstream and downstream stand is not allowed except the tension control The feed forward so called Cascade Speed Control CSC is used to maintain the stable speed ratio between the stands [6] With CSC the roll speeds of all upstream stands are changed accordingly when the roll

Comparison between simulations and the operation of the pilot rolling mill were performed which contributed to a simple model to predict the occurrence of thermal fatigue based on three rolling mill operational parameters reduction roll speed and temperature of the rolled material Additionally further studies were conducted regarding the abrasive behavior of roll microstructures and on

Hot strip finishing mill is initially set up with rolling conditions such as roll speed roll gap and cooling pattern obtained by a set up model To improve the accuracy of initial roll speed setting for a 7 stand finishing mill an equation for predicting forward slip and a compensation method for initial roll speed setting were proposed and applied for Hot Strip Mill at Pohang Steel

· Overly wide weld roll settings; Mill speed too fast for welded capabilities; Weld rolls worn beyond tolerance; Check It Often In general several tube mill areas should be checked on a regular basis This should be done at least monthly but should be based on the usage A higher production rate or running heavier metals through the mill requires more frequent checks Shafts should be checked

· Powder rolling mill Metal powder is introduced between the rolls and compacted into a green strip which is subsequently sintered and subjected to further hot working and/or cold working and annealing cycles Thin slab casting and rolling mill This is used for the production of hot strips Liquid steel is cast in thin slabs thickness 50 mm to 80 mm which are rolled in finishing
