FLOAT GLASS PRODUCTION DEVICE, AND FLOAT GLASS PRODUCTION METHOD EMPLOYING SAME

摘要

[Solution] A float glass production device having a water-cooled tube for cooling a bottom casing that covers the bottom part of the bottom brick of a bath filled with molten tin, the float glass production device being characterized in that, at least at the joint locations of the bottom brick, the water-cooled tube is furnished to the bottom part of the bottom casing while a heat transfer material is interposed therebetween, the heat transfer material having hardness of 10-50 (Asker C) and a heat transfer coefficient ?/d of 0.2 × 103-1.6 × 103 W/(m2 ° K), where the thickness d is 0.001-0.05 m; and a float glass production method employing the same.
