Fused tuckstone for glass furnace with skin microstructure
A recently granted patent (Publication Number: US11964900B2) discloses a fused tuckstone designed for use in glass furnaces. The tuckstone features a lower surface with a support surface resting on the furnace's metallic structure, a tank surface facing the tank's upper edge, and a lower transition surface connecting the two. The upper surface includes a superstructure surface for the superstructure's side wall and an upper transition surface linking it to the lower surface. Notably, the patent emphasizes a unique "skin microstructure" on certain surfaces with a crystal density exceeding four times that at a specific depth, evaluated by the number of crystals per surface area after polishing.
Furthermore, the patent details specific chemical compositions for the fused tuckstone, including mass percentages based on oxides such as Al2O3, ZrO2, and SiO2. The patent also outlines methods for producing the fused tuckstone, involving steps like mixing raw materials, casting molten material in a mold, and machining the outer surface to achieve the final product. Additionally, the patent extends to applications in glass furnaces, where the fused tuckstone is integrated into the superstructure as an intermediate layer between the metallic structure and the side wall. This innovative technology aims to enhance the performance and durability of glass furnaces by utilizing specialized materials and structures in their construction.
