Patent

CA 2334985

The invention concerns a method for producing a flame support for a gas burner, which consists in producing disjointed metal fibres (10) in an alloy comprising iron, chromium and aluminium; assembling the fibres together under pressure; bringing the fibre mat to a temperature sufficient to ensure a close bonding between the fibres. The invention is characterised in that it consists in feeding said metal alloy to an overflowing tank (3), to produce the fibres by cooling in contact with a mobile wheel (7); then in arranging in a moulding matrix the resulting disjointed fibres (10) and compressing them to form an agglomerated mat; then in connecting the mat to electrodes and a capacitor, thereby bringing the fibres (10), at their points of contact, to a temperature not less than their melting point, to produce fibres closely welded together, under high voltage.

Image L'invention concerne un procédé de support de flammes pour un brûleur fonctionnant au gaz, dans lequel on réalise des fibres (10) métalliques disjointes dans un alliage comprenant du fer, du chrome et de l'aluminium, on réunit entre elles sous pression ces fibres, on porte le mat de fibres à une température suffisante pour assurer une liaison intime entre les fibres. Selon l'invention, on alimente avec ledit alliage métallique un réservoir (3) à débordement, pour réaliser les fibres par refroidissement au contact d'une roue en mouvement (7), puis on dispose dans une matrice de moulage les fibres (10) disjointes obtenues et on les y comprime pour former le mat aggloméré, puis, on relie le mat à des électrodes et à un condensateur, et on porte ainsi les fibres (10), à leurs points de contact, à une température supérieure ou égale à leur température de fusion, pour provoquer un soudage des fibres exclusivement entre elles, sous haute tension.
