Heat shield arrangements for strip or billet-form material.

摘要

A heat shield arrangement for hot strip or billet-form material comprises insulating panels (2,4) that have a thin heat-resistant hot face (73) confronting the material and backed by a heat-insulating core (74,75). The panels are arranged in groups of two or more disposed side-by-side across the width of the material and the panels of said groups are displaceable with respect to each other for varying their heat-insulating effect over the lateral extent of the material. An array of laterally spaced temperature sensors (32) actuate said displacements of the panels.
