Method of melting vitreous materials and use of the suitable device for the accomplishment of the method

摘要

In a method of melting vitreous materials, the thermal energy to be supplied electrically to the vitreous mass is controlled by supplying the melting plant according to supplying cycles consisting of pre-established intervals of time during which the power applied to the plant is much higher than the maximum permissible input when the plant is continuously supplied, spaced by pre-established intervals of time during which the plant is not supplied. The length of said intervals of time is equivalent to an integral number of cycles of the alternating voltage acting on the electrodes.
