The float glass production line has been in service for seven years. The furnace's breast wall has been eroded by various complex atmospheres in the furnace, and frequent temperature fluctuations have caused localized inward tilting. This has led to the collapse of the breast wall bricks in furnaces 2 and 3 in the melting department. Temporary support has been provided using water packaging. Zircon bricks have been stacked underneath, forming an inverted trapezoidal shape due to limited operating space and high local temperatures, resulting in a configuration where the top is wider than the bottom and substantial gaps exist. This has exacerbated fire risks, with a potential collapse imminent.

Our solution involves utilizing ceramic welding technology to fuse the stacked refractory bricks with other wall surfaces inside the furnace, ensuring the safe operation of the breast wall.
