摘要

Oven for the preparation of glass by melting electric, electric glass melting process, and the installation of manufacture of glass wool.The invention relates to the technique of electric fusion in which the fusion energy is dissipated by Joule effect in the bath of molten glass through electrodes that plunge through the surface of the BThe lamb. According to the invention, electrodes are immersed in a bath of molten glass from a height of less than 800 mm of a surface s such that the ratio H / S is less than 0,5 M / m ^ 2 ^.According to another aspect, the exchange surface between the electrodes and the bath is higher than 0.075 m ^ 2 ^ / m ^ 3 ^ glass.Application to the manufacture of products using glass, such as insulating materials based on glass fiber.
