Title
(EN) GLASS MELTING FURNACE AND PROCESS FOR PRODUCING GLASS PRODUCT
(FR) FOUR DE FUSION DE VERRE ET PROCÉDÉ DE FABRICATION D'UN PRODUIT DE VERRE
(JA) ガラス溶解窯及びガラス製品の製造方法
Abstract
(EN)
A glass melting furnace comprising multiple steps rising along a molten glass lead-out direction from a mid portion of the deepest section within the glass melting furnace and crossing in the width direction orthogonal to the molten glass lead-out direction; a stage section extending along the molten glass lead-out direction from the highest one of the steps and crossing in the width direction; a threshold member crossing in the width direction on the step side of the stage section; and a bubbler crossing in the width direction between the upside of the lowest one of the steps and the threshold member. A slope may be used instead of all the steps.
(FR)
L'invention porte sur un four de fusion de verre comprenant de multiples gradins montant le long d'une direction de sortie de verre fondu à partir d'une partie moyenne de la section la plus profonde à l'intérieur du four de fusion de verre et traversant dans la direction de la largeur orthogonale à la direction de sortie du verre fondu ; une section d'étage s'étendant le long de la direction de sortie du verre fondu à partir du plus élevé des gradins et traversant dans la direction de la largeur ; un élément de seuil traversant dans la direction de la largeur sur le côté des gradins de la section d'étage ; et un barboteur traversant dans la direction de la largeur entre le côté supérieur du plus bas des gradins et l'élément de seuil. Une pente peut être utilisée au lieu de tous les gradins.
(JA)
 ガラス溶解窯であって、ガラス溶解窯の内部の最深部の途中から溶融ガラス導出方向に沿って昇段し、前記溶融ガラス導出方向に対して直交する幅方向に横断する複数のステップと、ステップの最上段から前記溶融ガラス導出方向に延伸し、前記幅方向に横断するステージ部と、ステージ部のステップ側で前記幅方向に横断する敷居体と、ステップの最下段のステップ上から敷居体との間で前記幅方向に横断するバブラーと、を有する。上記の全ステップの代わりにスロープを有していてもよい。
