Description

technical field [0001] The invention relates to the technical field of substrate glass manufacturing, in particular to an upper and lower layer electrode propulsion device and method of a glass kiln furnace. Background technique [0002] In the manufacturing process of glass substrates, the kiln pool is the key equipment for melting glass batch materials to form glass liquid. When making new high-performance glass (such as: liquid crystal basic glass, screen protection glass, LTPS glass), the furnace in the production line adopts a hot-top electric melting or electric-assisted melting furnace, and the current is introduced into the glass liquid through the electrode. The molten glass between the two electrodes generates Joule heat under the action of alternating current, so as to achieve the purpose of fully melting the glass batch material, preventing the lower layer of the molten glass from staying at a lower temperature for a long time and adjusting the temperature.

Problems solved by technology

[0003] During the heating process of electrofusion, due to the chemical purity of the electrode, metallographic structure, surface characteristics, initial protective layer, mechanical stress in the manufacturing process, etc., as well as the solute temperature, current density, and chemical composition of the glass, etc. The combined effect causes erosion of the furnace electrodes, and the Joule heat generated becomes smaller due to the increase of the electrode spacing, which cannot meet the melting requirements of the furnace glass liquid. It is necessary to push the electrodes into the furnace to meet the specified requirements for the electrode spacing of the pool furnace.

At present, the kiln electrodes are pushed in layers by cross-rotating six screws. The process of pushing the kiln electrodes by this method is cumbersome, and at the same time, it is easy to produce large propulsion errors. The upper water cooling plate and the lower water cooling plate divide the kiln electrodes into upper and lower parts. layer, during the advancement of the kiln electrode, due to the advancement of the upper and lower layers, the advancement of the upper electrode and the lower electrode is inconsistent and dislocation occurs, which will lead to the failure to achieve the expected advancement effect, and also greatly affect the service life of the electrode
