Normally, the entire bottom of the glass kiln is paved with 33#WS AZS brick, with a uniform thickness, and these bricks are placed on top of the insulation layer. When the glass kiln is operating, different parts of the glass furnace bottom are eroded to different degrees. After the AZS bricks in the severely eroded parts are completely eroded, the insulation layer will be eroded faster, affecting the safe operation of the glass kiln. Therefore, it is necessary to strengthen the corrosion resistance of materials in severely corroded parts to ensure the safe operation of the kiln.The bricks used for the areas with serious corrosion should be adjusted according to the actual furnace conditions.
The maximum erosion here is mainly caused by the mechanical erosion of the raw materials and the erosion of the metal substances contained in the glass raw material. In this area, the corrosion resistance of the material should be strengthened, and the 33# AZS bricks should be replaced with 41# AZS bricks that are more resistant to corrosion.
When the glass pool adopts full insulation and bubbling technology, the glass liquid near the bubbling bricks has a higher temperature and a higher flow rate. The pool bottom paving bricks on both sides of the bubbling bricks are relatively damaged. The traditional 33# AZS bricks should also be adjusted to 41# AZS bricks with stronger corrosion resistance.
The surface temperature of the electro-boosted molybdenum electrode at the bottom of the glass kiln can reach 2000°C. There will be serious corrosion for the electrode hole bricks at high temperatures. Therefore,for the electrode hole 41#AZS bricks should be selected. The 41# AZS tiles have better erosion resistant performance.
The liquid hole is the concentrated outlet for all the glass liquid. The mechanical erosion caused by the flow of glass liquid here not only impacts the liquid hole legs and the liquid hole cover, but also the pavement tiles at the bottom of the pool.It is also particularly important to enhance the corrosion resistance of the pool bottom paving bricks here. In this area,41#AZS pool bottom paving bricks should be used to balance the erosion status with other parts.
Reasonable adjustment of the material at the bottom of the glass kiln will achieve better results and extend the service life of the glass kiln.
