The large arch of the melting part of the float glass furnace was eroded by fuel atmosphere; small rat holes at the top of the melting pool were enlarged as a result of arch bricks shrink due to a long time of erosion by the flame, and flame penetrated from the holes. By using the traditional hot repair methods, it is difficult to achieve a good maintenance effect and a long service life, once the inappropriate hot repairing measures are adopted, the repair agent may drop into a melting pool or a large area of arch bricks shrink, thus posing a great threat to safety during production. With our unique high temperature ceramic soldering technology, and with surveillance camera footage, the shrunk part can be soldered accurately and safely, and the thickness of weld, weld range, weld quality are completely controllable and your safe operation of the kiln can be escorted
