Abstract

The invention discloses a casting method for glass block whose quality is at least 500kg, wherein glass molten substance 22 is cast in a metallic mold 26 which is lined with a ceramic heat guard 30, the ceramic heat guard can be separated with the metallic mold 26, and heat conductivity is optimized to 0.2W.K-1.m-1-2.0W.K-1.m-1 in the range of 800 DEG C-1400 DEG C.

Description

Method and apparatus for casting glass blocks technical field The invention relates to a method of casting glass blocks having a mass of at least 500 Kg. The invention also relates to casting molds suitable for casting glass goblets of this size and suitable for use in mass production. Finally, the invention relates to equipment for casting large glass goblets. Background technique Bach, Hans (ed.): "LowThermalExpansionGlassCeramics", SpringerVerlagBerlin, Heidelberg, New York, 1995, ISBN: 3-540-58598-2, pp. 107-214 describes a technique for the production of a glass-ceramic produced by the applicant Production and distribution. is a lithium aluminosilicate glass-ceramic material that exhibits particularly low thermal expansion and high stability and is widely used as a substrate in precision applications, e.g. for the manufacture of lenses for telescopes of large dimensions, but can also be used on small scales The manufacture of precision components, for example for...
