<p>PCT No. PCT/FR98/01597 Sec. 371 Date Jun. 7, 1999 Sec. 102(e) Date Jun. 7, 1999 PCT Filed Jul. 21, 1998 PCT Pub. No. WO99/05068 PCT Pub. Date Feb. 4, 1999The invention relates to the electric melting technique, in which the melting energy is dissipated in the bath of melted glass as a result of the Joule effect by means of electrodes which dip through the surface of the bath. According to the invention, the electrodes dip into a bath of melted glass which has a height h below 800 mm and a surface S such that the ratio h/S is lower than 0.5 m/m2. According to another aspect, the exchange surface between the electrodes and the bath is above 0.075 m2/m3 of glass. The invention is used in the manufacture of glass-based products, such as insulating materials based on glass fiber.</p> |
