Abstract
A rolling mill has a plurality of rolls, means to direct liquid coolant on to the rolls at the ingoing side of the mill mounted on backing supports and a casing or casings enclosing the directing means during operation. The casing or casings have contact seals engaging the rolls to prevent unwanted egress of coolant on to work entering the mill. Sealing means are provided between the casing or casings and the backing support or supports and the casing or casings can be withdrawn from the mill for maintenance purposes independently of said one or more backing supports.
