20100083705 | METHOD FOR MANUFACTURING DECORATIVE FLAT GLASS USING HORIZONTAL TEMPERING FURNACE - Provided is a method for manufacturing a decorative plate glass using a horizontal tempering furnace including, attaching crystal ice onto a surface of a plate glass, and subjecting the plate glass to a rapid heating and quenching treatment using a horizontal tempering furnace, the method further including: providing crystal ice whose constituent components are regulated such that a melting point temperature of the crystal ice is formed within the set range of the melting point temperature of the crystal ice defined as a toughening temperature of a pane core to 1O0 C above; attaching the crystal ice onto a surface of the plate glass, and rapidly heating the plate glass at a heating temperature inside the horizontal tempering furnace that corresponds to the set range of the melting point temperature of the crystal ice in the horizontal tempering furnace, wherein the rapid heating is performed by controlling a heating time using a first control factor which is readily set with respect to a heating time at the toughening temperature of a float glass; and rapidly cooling the crystal-ice-melt-attached plate glass by controlling cooling conditions using a second control factor which is readily set corresponding to the cooling conditions for toughening the float glass after the rapid heating. | 04-08-2010 |
