Refractory fiber spraying is a new refractory technology for mechanized construction of fiber lining. Refractory fiber spraying is essentially the second generation technology of refractory fiber lining. Just like the development of heavy refractory linings, the first generation of bricklaying developed to the second generation of monolithic refractory casting, a breakthrough in material shape and construction technology. Since the first generation of refractory fiber furnace lining technology was applied in the early 1980s, fiber products (felt, board, block and blanket, etc.) were used to manually paste and install in the furnace. This method. -Directly affect the service life of the furnace lining.
Refractory fiber spraying is to send the pretreated bulk refractory fiber cotton out of the spray gun at high pressure through a special spraying machine. At the same time, the binder is evenly sprayed into the fiber after being atomized by the outer ring of the spray gun through the glue pump. Knock down the inner wall of the furnace. The external mixing method enables the fiber cotton to be attached to the sprayed surface in the form of flakes. The lining layer on the sprayed surface is basically a three-dimensional network structure. Spraying can form a uniform and seamless lining of the entire furnace with good sealing. The overall product structure, its surface is smooth and smooth, there is no oven requirement, and the intermittent kiln saves about 30%.
