A hot-blast main for a hot-blast stove system of a blast furnace has a refractory structure comprising a plurality of courses of refractory bricks. At least a first one of the courses has at least one part thereof comprised of a plurality of expansion-joint forming bricks whose dimensions and arrangement are such that, in the cold condition of the hot blast main, there are provided radial expansion joints between the expansion-joint forming bricks and at least one adjacent part of the hot-blast main. At least some of the expansion-joint forming bricks of the first course are placed radially staggered relative to at least one adjacent such brick in each case, so that the expansion joints are provided at both the radially inner side and the radially outer side of said first course. This construction accommodates differential thermal expansions and provides good stability of the structure.

Conduite à vent chaud pour four à air chaud de haut fourneau, comprenant une structure réfractaire constituée d'un certain nombre de rangées de briques réfractaires. Au moins une des rangées est constituée de briques formant des joints de dilatation qui, en raison de leur dimension et de la façon dont elles sont disposées, permettent de former, dans la condition à froid de la conduite à vent chaud, des joints de dilatation radiaux entre les briques et au moins une partie adjacente de la conduite à vent chaud. Au moins quelques-unes des briques formant des joints de dilatation de la première rangée sont disposées radialement en quinconce par rapport à au moins une autre de ces briques adjacentes dans chacun des cas, afin d'obtenir des joints de dilatation, à la fois, sur le côté radial interne et sur le côté radial externe de cette première rangée. Ce type de construction accommode les écarts de dilatations thermiques et fournit une bonne stabilité à la structure.
