How to perform hot repair on the bricks of the regenerators

Under the erosion of flames and powder, the lattice bricks of the regenerator are gradually melted into tumors, causing the lattice body to be blocked or even collapsed, the heat storage capacity is reduced, and the exhaust gas is difficult to discharge, which affects the melting. At present, most of the lattice bricks in the regenerators of large and medium-sized glass factories in China use fused bricks with strong alkali resistance, which prolongs the life of the lattice body. However, in recent years, in order to reduce costs, the use of petroleum coke powder as fuel will have a destructive effect on the alkaline lattice.
The practice of hot repairing lattices is similar in all factories. Generally, the fast is only 24h, and the slow is about 48h. It mainly depends on the burning of the lattice body and the connection of the steps of the hot repair method and the coordination of various work arrangements.
Hot repair will cause pressure and temperature fluctuations in the kiln, the longer the time, the greater the impact. After the door is closed after the hot repair, the temperature in the kiln will change. The melting worker must be aware of it and adjust it in time to ensure the normal production of the kiln. Connected regenerator. During the hot repair, the melter should keep close contact with the hot repair personnel to grasp the progress of the hot repair. For safety, a warning sign should be hung. accident.
