Abstract

See full text

A rolling mill roll neck is sealed by interposing a seal between a roll flinger having a first axial surface and an opposing second axial surface of a roll housing retaining plate. The seal is biased into contact against one of the axial surfaces with a pressurized fluid source, such as compressed air. As the seal wears during roll neck operation the pressurized fluid maintains biasing contact between the seal and the axial surface. The remainder of the intact seal is remains pressed into contact with the mating, opposing axial surface, for example that of a roll flinger or a retaining plate. Advantageously the seal is housed in a stationary retaining plate that is in opposed axial relationship with a rotating flinger.
