Universal Rolling Mill: The universal rolling mill consists of two vertical rolls and two horizontal rolls. The vertical rolls are idle and are arranged between the bearing chocks of the horizontal rolls in the vertical plane. Universal rolling mills are used for producing blooms from ingots and for rolling wideflange Hsection beams.
