The glass-ceramic forming device provided by the embodiment of the present invention places molten glass in a rotating horn-shaped drum, so that the glass liquid is evenly diffused on the inner surface of the horn-shaped drum under the action of centrifugal force, and due to the The cylinder is inclined downward toward the large mouth end, so that the glass liquid on the inner surface of the horn-shaped cylinder moves along the large mouth end of the trumpet-shaped cylinder while spreading evenly, so as to achieve the purpose of thinning the glass plate. At the same time, the width of the formed glass plate can be adjusted by adjusting the inclination angle of the horn-shaped rotating drum, and the thickness of the formed glass plate can be adjusted by adjusting the rotating speed of the horn-shaped rotating drum.
Description
technical field [0001] The invention relates to the technical field of glass production, in particular to a forming device and a forming method of glass-ceramics. Background technique [0002] Glass-ceramics refers to the basic glass with a specific composition added with a crystal nucleating agent (or without a crystal nucleating agent). It is crystallized and heat-treated under a certain temperature system, and a large number of tiny crystals are uniformly precipitated in the glass to form a dense micro-crystal. A multiphase complex of crystalline and glassy phases. By controlling the type, quantity and size of crystallites, transparent glass-ceramics, glass-ceramics with zero expansion coefficient, surface-strengthened glass-ceramics, glass-ceramics of different colors or machinable glass-ceramics can be obtained. [0003] In the traditional production of glass-ceramics, the molten glass needs to be calendered, but the traditional calendering usually uses two counter-rot...
