Abstract:
An electrically heated melting furnace for the melting of mineral materials, such as frits, (vitreous) enamels and the like, wherein a bath of molten material contained in a tank is heated by means of electrodes contacting the molten material and having a current flowing therethrough which heats the molten material by Joule's heat, wherein a batch is fed onto the melt or molten bath, and the molten product is withdrawn from the bottom of the tank wherein the furnace space or tank having the molten bath has a square or almost square cross-section or the cross-section of a regular polygon; that the depth of the furnace space or tank having the molten material therein corresponds almost to the diameter of the tank; and that a plurality of radiator heating rods are arranged above the batch material and said heating electrodes are positioned in the lower portion of the molten bath above the tank bottom and comprising a bottom outlet including a cylindrical portion or element and a further underlying, concentrically disposed, circular disc-shaped or annular portion or element of a refractory material being conductive at high temperature and acting as an electrical conductor, which elements are conductively coupled to a current supply line.
Abstract:
The temperature or temperature profile of an electrically conductive molten mass heated by electrodes immersed therein is measured during continuous operation by momentarily cutting off the electrical energy supplied to the heating electrodes, passing measuring currents through the molten mass via the heating electrodes during the momentary cut off, measuring the electrical resistance between pairs of heating electrodes in measuring paths defined by such electrodes and then calculating the temperature existing within the individual measuring paths on the basis of the measure resistance values.
