FIELD: metallurgy.
SUBSTANCE: fireproof board of slide gate has metallic band. For thermal expansion compensation on band there are implemented register ledge in a kind of local strained areas or in a kind of calipers, joined permanently with band surface. As a variant, board is outfitted by centering facility in a kind of, at least, one pair of clamps or fixing gutters, placed on band edge astride of board longitudinal axis, from the side of its contact base plane. Seat of carriage and/or mounting frame of slide gate are implemented by clamps or fixing gutters for complied them fixing gutters or clamps of fireproof board.
EFFECT: reliability improvement of boards and increasing of slide gate working resource.
