FIELD: building industry; tunnel furnaces for production of block lightweight building materials. ^ SUBSTANCE: the invention is pertaining to the tunnel furnaces for production of the block lightweight building materials. The technical result of the invention consists in the increased furnace capacity. The tunnel furnace is made in the form of the double-level tunnel. Each level has the zones of foaming, quenching, stabilizing and annealing, the heaters power adjustment both from above and from below of each zone. In the tunnel furnace there are dollies for relocation of the molds. The lower heaters of each level are disposed in the form of two longitudinal rows, between which there is the central guide as the support for the dollies. The central guide is made in the form of the U-beam. Each dolly is supplied with the additional wheels: the central wheel mounted vertically and the front wheel mounted horizontally engaged from the inside with the horizontal ledge and the lateral ledges of the central guide. ^ EFFECT: the invention ensures the increased furnace capacity. ^ 3 dwg |
