A heat shield arrangement for hot rolling mills

摘要

Heat shield panels (4) arranged below a hot material path are supported in a manner which allow limited movement. Carry-over bars (10) at opposite ends of each panel are also displaceably mounted and have bearer elements (20) which lie below the panels. When a carry-over bar is struck by distorted material, it will be momentarily displaced and, through supporting engagement of the bearer elements with the panel, displacement of the panel also occurs, so disturbing loose deposits on its top faces (4c). Occasional agitation of the panels is thereby provided passively and the build-up of deposits on a panel top face can be countered in a manner which allow the angle of slope of the top faces to be reduced.
