Regardless of the construction of refractory fiber blankets on furnace walls, furnace roofs, furnace doors, flues, or joints between two or more places, care must be taken to prevent the refractory fiber blankets from being squeezed out. When slag wool is used for furnace walls, the refractory fiber blanket must be isolated from the high temperature zone.
The structure of stacked refractory fiber blankets is fixed by needling. The refractory fiber blanket is cut into rectangular fiber strips with the same width as the furnace wall and fixed with pins of heat-resistant steel. After fixing with pins, place the compressed refractory ceramic fiber blanket on the upper support plate and insert the pins into the fiber strips to prevent tilting or leakage.
Formwork fixing is another form of lamination where a refractory ceramic fiber blanket is folded and compressed into modules. There are two ways to repair the module. One method is to weld the formed modules to the furnace shell, and use bolts to insert and fix the refractory fiber modules to the furnace shell.
Another method is to glue and fix the refractory ceramic fiber blanket into a rectangular shape, fold it, and stick it to the lining with adhesive. When pasting, apply adhesive on the optical fiber module and press it with a wooden trowel to make it firmly bonded. Do not press on refractory fiber modules that are stuck during stamping. This method is widely used in construction.
