Abstract: A consecutive molding method for crystallized glass comprises: a process to obtain molten glass by melting glass raw materials; a process to obtain a band-shaped plate glass by roll forming the molten glass; a crystallization process to obtain a band-shaped crystallized glass plate by conducting thermal treatment on the band-shaped plate glass to crystallize it; and a process to cut the band-shaped crystallized glass plate, wherein the crystallization process includes: a process to form crystal nuclei in the band-shaped plate glass by disposing it in the atmosphere of a crystal nucleus-formation temperature and retaining it at the temperature; a process to raise the temperature of the band-shaped plate glass with crystal nuclei to a crystal-growth temperature; a process to retain the band-shaped plate glass with crystal nuclei at the crystal-growth temperature to produce a band-shaped crystallized glass plate; and a process to slowly cool down the band-shaped crystallized glass plate.

Abstract: A consecutive molding method for crystallized glass comprises: a melting process to obtain molten glass by melting glass raw materials; a molding process to obtain a band-shaped plate glass by roll forming the molten glass to become band-shaped; a crystallization process to obtain a band-shaped crystallized glass plate by conducting thermal treatment on the band-shaped plate glass to crystallize it; and a cutting process to cut the band-shaped crystallized glass plate, wherein the crystallization process includes: a temperature-raising process to produce the band-shaped crystallized glass plate by disposing the band-shaped plate glass obtained in the molding process, in the atmosphere of a crystal nucleus-formation temperature and raising the temperature to a crystal-growth temperature or above to grow crystals as well as form crystal nuclei; and a slow-cooling process to slowly cool down the band-shaped crystallized glass plate.
