HEAT SHIELDS

摘要

A heat shield arrangement for strip material employs insulating panels that include an upper series displaceable upwardly by power actuation means to avoid damage by buckled or lifting material. Protective elements projecting below the upper panels are associated with sensing means to actuate the raising of the upper panels and are on mountings able to have a limited displacement before the raising of the upper panels is actuated. The power actuation means act on said mountings to determine the minimum force from the material that causes raising of said panels. To lead in deformed stock there is an increased height entry region comprising a reinforced upper structure, possibly followed by upper and lower insulating panels at decreasing heights from each other to merge into a main region of limited height. The panels may have heating means to give the strip a more uniform transverse temperature profile.
