With the high strength of the refractory fiberboard application plan, the use of wind-resistant hard fiber wall linings is becoming more and more widely used. It is necessary for the hard products to be produced by the vacuum forming process. Together, the ratio of the binder, aggregate, and additives involved in the production of different products They are all different.
Since their inception, polycrystalline mullite fiber (72% AlO) and polycrystalline alumina fiber (80%, 95% AlO) have been successfully used in metallurgy, petrochemical, and electric porcelain kilns above 1300 degrees Celsius. However, due to Polycrystalline fiber production technology and process constraints, now only can supply bulk polycrystalline fiber laminates, and the laminates are composed of fiber veneer components with a standard of 300mm*300MM*30mm~50mm, and the component density is 100Kg/M, fiber laminates The components are pasted on the refractory brick wall by adhesive.
In addition, the high-aluminum fiber is mixed with polycrystalline alumina fiber (or polycrystalline mullite fiber) in a certain proportion to produce mixed fiber products using vacuum forming technology, which can be used as a high temperature furnace wall of 1250°C to 1300°C Lining and refractory fiberboard application components are the primary conditions for advancing the development of refractory fiberboard application skills. Regarding the large-scale furnace fiber wall lining, the traditional layered fiber lining has been replaced by fiber component linings of different structures. This development trend has promoted the development of refractory fiberboard. The development of fiberboard application parts, and some professional production of refractory fiberboard application skills have appeared.
