What are the characteristics of the gas flow in the flame space of a glass furnace?
The main raw materials of flat glass are: silica sand (sandstone), sodium carbonate, feldspar, dolomite, limestone and mirabilite. Process: 1, raw material crushing: the raw materials are crushed into powder; 2, weighing: according to plan the list of ingredients said powder can take a certain amount of; 3, will be called: the mixed powder mixing, stirring into a batch (colored glass and colorant);
Ordinary glass plate glass, wire glass and quartz glass (also known as crystal glass) a molding. Wired glass as the quartz glass; only a raw material of sandstone or silica or quartz sand. Tempered glass is made of flat glass as raw material for re processing: the cut of the flat glass into the tempering furnace, heating to about 650 degrees, with cold air quenching, glass forming hardening - tempering. Accomplish!
Melting: mix into the glass melting furnace, at 1700 degrees of melting into glass liquid; 5, molding: the glass liquid into a tin bath (float), pull machine (lattice method), rolling machine (rolling method, adding metal wire is wire glass), forming the flat glass; 6, annealing: the glass forming into the annealing furnace annealing, stress balance, prevent from breaking crack. Finally, inspection and packing.
