industry. SUBSTANCE: method involves attaching ceramic fiber material to metal frame by means of metal anchors, which are designed as cramps with bent legs. Ceramic fiber material is preliminary compressed. The bent support legs of anchors are welded to frame in rows in checkered order. Firstly, method involves welding front legs of previous row and front legs of next row, so that distance between base of back leg of previous row and base of front leg of next row is within range of 5-10 mm. Then, anchors are bent, starting from first row with respect to frame edge. Then, compressed packets of ceramic fiber material are arranged in rows and back legs of anchors are welded. Additional compression of ceramic fiber material is achieved by means of additional compression of anchors in center by 15-30 mm. This also ensures quality of anchor welding. EFFECT: increased reliability and service life of heat insulation, double or triple decrease in power consumption, decreased costs of mounting and using heat insulation. 1 tbl, 1 ex |
