Rolling Of Steel In A Modern Long Product Rolling Mill
Hatt, Raymond John (Bundaberg, AU) Wilson, David John (Bundaberg, AU) A known type of mill is a three roll mill which consists of two bottom rolls next to each other and a top roll, the arrangement being that the centres of the roll shafts form a triangle. Much research and development has been undertaken to improve the efficiency of.A Hille 100 rolling mill with rolls of 225 mm diameter and 254 mm length, driven by a variable speed DC motor of 75 horse power, was used. The maximum rolling force, torque and speed are 1500kN, 13kN m and 70 rpm respectively. The sensor roll nitrided surface hardness is 65 to 70 HRC.
