ABSTRACT:
A heat shield arrangement for strip material employs insulating panels of thin-walled composite construction. The panels include an upper series displaceable upwardly by power actuation means to avoid damage by buckled or lifting material. Protective members projecting below the upper panels are associated with sensing means to actuate the raising of the upper panels and can have a limited displacement before the raising of the upper panels is actuated. The power actuation means can themselves act on the sensing means to determine the minimum force from the material that causes raising of said panels. Control means displace the panels in response to the sensed transverse temperature profile to maintain the profile more uniform and some of the panels may have heating means for this purpose.
