The pool wall bricks at the blast hole of the horseshoe flame glass furnace are often corroded by strong alkalies and the pulling force of the glass melt, resulting in two erosion seams measuring approximately 2000 mm × 200 mm. These seams cause glass melt leakage and prevent the liquid level from reaching normal heights. Further corrosion would require lowering the glass melt level even more, affecting the operation of the plate pulling machine and potentially causing production stoppages due to plate detachment.

To address these issues, the glass melt level is initially lowered below the lower edge of the erosion seam. Our company's ceramic welding technology is then used to repair the erosion seam. After welding, the glass melt level is restored to normal, thereby extending the furnace's service life by one year.
