Abstract

The invention relates to electric furnaces of direct heating of skull type for one-step production of products and can be used in glass prom. The purpose of the invention is to improve the quality of the glass without further increasing the power and current density at the electrodes. The electric skull glass furnace includes a copper case 1 with water cooling in the center of which a molybdenum bowl 4 is installed, which is with a zero electrode. Phase electrodes 3 are inserted through the furnace walls. The molybdenum bowl is made in the form of a truncated trihedral pyramid, and the phase electrodes are made with a working surface parallel to the edges of the pyramid. The device allows to intensify the processes of homogenization and clarification. 2 Il.

After reaching the optimum mog .:

0 of part 10 of the drainage track it becomes possible to stretch the tubes or rods with a thin machine installed under the outlet of the furnace

The proposed electric skull glass furnace provides an increase in the temperature of the glass mass above the drain hole of the central electrode va due to a decrease in its amount in the most heated electrode electrode above the central electrode, which leads to an increase in the rate of clarification due to an increase in the lifting force of the bubbles and the change in gas solubility

The direction of the working streams of glass masses coming out of the interfing zones, at the angle of another one, also contributes to a better desensitization of the drainage in the youth and prevents the newly charged charge from penetrating into it, which will force you to get high-quality tubes from the RF bottom light. highly alkali free alkali glass and glass containing barium oxide
