Title (EN) REFRACTORY BLOCK FOR A GLASS-MELTING FURNACE
(FR) BLOC REFRACTAIRE ET FOUR DE FUSION DE VERRE
Abstract:
(EN) The invention relates to a molten refractory product having the following average chemical composition in wt % on the basis of oxides and for a total of 100%: ZrO2: 30-46%; SiO2: 10-16%; AI2O3: the remainder until 100%; Y2O3 ≥ 50/ZrO2 and Y2O3 ≤ 5%, Na2O+K2O: 0.5-4 %; CaO: ≤ 0.5%; Other species : ≤ 1.5%. The invention can be used for a glass-melting furnace.
(FR) La présente invention concerne un produit réfractaire fondu ayant la composition chimique moyenne suivante, en % en masse sur la base des oxydes et pour un total de 100% : ZrO2 : 30 - 46%; SiO2 : 10 - 16%; AI2O3 : complément à 100%; Y2O3 ≥ 50/ZrO2 et Y2O3 ≤ 5%, Na2O+K2O : 0,5 - 4 %; CaO : ≤ 0,5%; Autres espèces : ≤ 1,5%. Application à un four de fusion de verre.
