Patent granted for fused tuckstone with specific crystal density
A recently granted patent (Publication Number: US11964900B2) discloses a fused tuckstone designed for use in glass furnaces. The tuckstone features a lower surface with specific characteristics, including a support surface for resting on a metallic structure, a tank surface facing the tank edge, and a lower transition surface with a unique crystal density. The upper surface of the tuckstone is intended to receive the superstructure's side wall, with an upper transition surface connecting it to the lower surface. The patent emphasizes the crystal density of various surfaces within the tuckstone, with specific requirements outlined for different parts of the structure.
Furthermore, the patent details the chemical composition of the fused tuckstone, highlighting the percentage of oxides such as Al2O3, ZrO2, and SiO2. The document also includes claims related to the presence of a zirconia stabilizer, the distribution of oxide types, and the crystal density requirements for different surfaces. Additionally, methods for the production of the fused tuckstone are described, involving steps such as mixing raw materials, casting molten material, and machining the intermediate piece to obtain the final tuckstone. The patent also covers the integration of the tuckstone into a glass furnace structure, emphasizing its role in supporting the superstructure and tank while maintaining specific surface characteristics.
