Title (EN) A METHOD FOR REMOVING REFRACTORY CONCRETE BY USING EXPLOSIVES IN INDUSTRIAL EQUIPMENT
(FR) PROCEDE PERMETTANT D'ELIMINER LE BETON REFRACTAIRE DANS L'EQUIPEMENT INDUSTRIEL A L'AIDE D'EXPLOSIFS
Abstract: front page image
(EN)One describes a method for removing refractory concrete by using explosives in industrial equipment, which consists in making bores (3) in refractory concrete (2), which is fixed by clamps (10) onto a metallic structure (1); said bores (30) are loaded with an explosive load (4) and duly confined (5), and then interconnected by means of strips of detonating cord (6), and knots (7) are made to link these strips of detonating cord (6) to the trunk lines of string (11), which may contain delays (8) in appropriate places, the whole forming the so-called explosive network. After this mounting, the explosive network (12) is actuated by means of a starter (9), and the removal of the refractory concrete (2) takes place.
(FR)La présente invention concerne un procédé permettant d'éliminer le béton réfractaire dans l'équipement industriel à l'aide d'explosifs. Selon le procédé précité, on perce des trous (3) dans le béton réfractaire (2) qui est fixé par des brides de fixation (10) sur une structure métallique (1), on charge les trous (3) avec une charge explosive (4) dûment confinée (5), on les relie ensuite entre eux à l'aide de bandes de cordeau détonant (6) et on fait des noeuds (7) pour relier ces bandes de cordeau détonant (6) aux lignes de corde principales (11), qui peuvent contenir des retardateurs (8) en des endroits appropriés, le tout formant le réseau appelé explosif. Après cet assemblage, on actionne le réseau explosif (12) au moyen d'une amorce (9) et on élimine le béton réfractaire (2).
