Abstract (en)
Construction process of a furnace with open chambers intended for the firing of blocks containing carbon, constituted by a plurality of chambers arranged in series in one or two parallel rows, each chamber being contained in an independent shell made of concrete formed from a floor (12) and from lateral coverings (11) made of concrete. Arranged on each covering (11) is a plurality of vertical abutments which are subjected to prestressing in the vertical direction. <??>This prestressing is applied by means of at least one steel cable (15) fixed, at both ends, to a metal plate (17) which comes to bear against the base and the top of each abutment (14). <??>It is also possible to subject to tension upper parts of the transverse walls by means of at least one metal tie rod arranged horizontally and subject to adjustable tension. <IMAGE>
