Description

Technical Field

[0001] The present application relates to the technical field of glass manufacturing, and more specifically, to a high-performance electrode heating element for a glass furnace. Background Art

[0002] Electrodes are often used in glass furnaces to melt glass. When current passes through the electrodes and enters the glass material, the current is converted into heat energy (Joule heat) due to the resistance of the glass. This heat energy is enough to make the glass reach its melting point (usually between 1000℃ and 1500℃). The continuous passage of current causes the temperature to continue to rise, causing the solid glass raw materials to gradually melt and become liquid. During the addition of cold glass material, the resistivity of the glass liquid will fluctuate, affecting the efficiency and effect of the glass furnace on the melting of the glass.

[0003] After searching, the patent document with the existing publication number CN118145870A provides a bottom-inserted electrode, electrode system and propulsion method for auxiliary heating of a glass kiln. The method measures the loop voltage and loop current of the molybdenum electrode, and then calculates the measured loop resistance, thereby calculating the erosion amount of the molybdenum electrode, and then calculates the propulsion amount of the molybdenum electrode, and adjusts the length of the molybdenum electrode extending out of the glass kiln according to the erosion amount.

[0004] Although the above method can maintain the temperature in the furnace and increase the efficiency of glass melting by adjusting the length of the molybdenum electrode extending out of the glass furnace, the reciprocating extension method of the molybdenum electrode is likely to cause wear of the molybdenum electrode and reduce the service life of the molybdenum electrode. In view of this, we propose a high-performance electrode heating element for a glass furnace. Utility Model Content

[0026] Among them, the electrode body 2 is made of molybdenum, which has good wettability, low contact resistance and will not color the glass when in contact with the glass melt. It has good corrosion resistance to most glass melts and is an ideal material for a heating electrode for glass melting. In order to avoid wear between the electrode body 2 and the mounting seat 1, a protective sleeve 6 is provided on the outside of the electrode body 2. The protective sleeve 6 is made of silicon nitride ceramic material. Silicon nitride has excellent mechanical strength and thermal stability. Even at high temperatures, it can maintain high strength and toughness, and can provide effective protection for the electrode body 2. The bent end of the electrode body 2 extends out of the protective sleeve 6. A limiting ring is fixed on the outside of the protective sleeve 6.
