Using self-made composite binder, adding a variety of special micro-powder, with the help of imported thermal infrared imager to detect the heating parts of the furnace body, circle the weak position of the furnace lining, find the correct pressure into the repair position, and implement targeted repair, so as to achieve the purpose of intelligent repair without affecting production and changing the internal structure of the furnace body. 1, with good fluidity and pressure into the construction performance; 2. Good sintering and low linear change rate; 3. After condensation, it becomes gelatinous, and the furnace shell and furnace lining are firmly bonded, which can effectively prevent gas leakage, improve the service life of the product, and make the repair lining body have good stability.
