Abstract
Replaceable heat insulation is provided for water-cooled pipes comprising structural supports and skid rails in slab reheating furnaces and like high-temperature metallurgical furnaces wherein the insulation is comprised of two mating sections of convenient length arranged to surround or, in the case of skid rails, largely surround the water-cooled pipes, the sections having metal fastening at their confronting edges brought into interfitting relation by sliding one section along the pipe relative to the other with provision for tightening the sections against the surface of the pipe and bringing portions of the interfitting metal fastenings into heat conducting contact with the water-cooled pipe. When each pair of sections has been fitted about the pipe and interlocked, but before being tightened about the pipe, each pair after the first is slid as a unit along the pipe into abutting position against the exposed end of the preceding pair and when so positioned being then firmly tightened about the pipe. Removal of the refractory sections for replacement from time to time is easily effected without removal of fastenings that are welded to the surface of the water-cooled pipes.
