Ceramic Fiber Product Series
◎ Ordinary ceramic fiber blow‑in cotton is produced by electrically melting coal gangue and employing a blow‑in fiber‑forming process.
◎ Standard ceramic fiber spun cotton is produced by electrically melting coal gangue and using a spinning‑fiber process.
◎ Ceramic fiber spun cotton is manufactured by electrically melting an alumina–silica mixture and applying a spinning‑fiber process.
◎ Ceramic fiber blankets are produced continuously and, after needle-punching, feature uniformly interwoven fibers with high tensile strength, containing no binders.
◎ Needle-punched blankets of varying bulk densities and thicknesses offer users a wide range of material options to achieve optimal insulation performance and cost-effectiveness.
◎ Ceramic fiber blankets exhibit excellent resistance to chemical attack (except for hydrofluoric acid, phosphoric acid, and strong alkalis such as Na2O and K2O).
◎ The performance of ceramic fiber blankets is unaffected by oil exposure; their thermal and physical properties can be fully restored upon drying.
Ceramic fiber vacuum‑formed wet‑laid felt is manufactured using ceramic fiber wool produced by the resistance‑fused blow‑spinning process, and is shaped via a vacuum‑forming technique. ◎This ceramic fiber vacuum‑formed wet‑laid felt is a lightweight, flexible refractory fiber insulation material, composed of high‑purity refractory oxides combined with an organic binder. ◎In addition to inheriting the excellent properties of its loose‑fill counterpart, this product also exhibits superior strength and elasticity, making it a versatile material. It is suitable for expansion joints in furnace and boiler linings as well as for high‑temperature gaskets. When used as a gasket, its outstanding resistance to molten metal penetration makes it ideal for sealing ingot ladle bottoms, plug‑rod core gaskets, and aluminum billet casting gaskets.
Standard ceramic fiber boards are manufactured on an advanced, continuous-flow production line that employs state-of-the-art processing technologies.
Ceramic Fiber Prefabricated Panel / Firestop Panel
The ceramic fiber panels and fire barriers are manufactured from ceramic fibers using a vacuum‑forming process. The development of this product aims to produce rigid, self‑supporting panels with excellent high‑temperature performance.
Ceramic fiber paper is manufactured from high-purity ceramic fibers and is used in high-temperature thermal insulation applications. Advanced production techniques ensure highly uniform fiber distribution, while the paper’s thickness and bulk density are tightly controlled.
High‑temperature ceramic fiber textiles, including fabrics, ropes, tapes, and yarns, are manufactured through specialized processes using ceramic fiber cotton, alkali‑free glass filaments, and high‑temperature stainless steel alloy wires. In addition to these standard products, we also offer custom‑specification, high‑performance textiles tailored to specific operating temperatures and application requirements.
Shaped ceramic fiber components
Ceramic fiber shaped components are manufactured from high‑quality ceramic fiber wool using a vacuum‑forming process. The development of this product aims to produce rigid, self‑supporting shaped parts that exhibit excellent high‑temperature performance.
Various ceramic fiber modules are manufactured by processing needle‑punched ceramic fiber blankets of the corresponding material on specialized machinery, according to the fiber assembly’s structure and dimensions. During fabrication, a controlled degree of compaction is maintained to ensure that, once the module wall lining is installed, the differential thermal expansion of each module in different directions causes the modules to press tightly against one another, forming a seamless monolithic structure. Furthermore, these ceramic fiber modules can be directly secured to the steel anchor studs of the industrial kiln shell using various types of anchoring devices.
Various ceramic fiber folding blocks are manufactured by processing needle-punched ceramic fiber blankets of the corresponding material on specialized machinery, according to the fiber assembly’s structure and dimensions. During fabrication, a controlled degree of compaction is maintained to ensure that, once the ceramic fiber folding blocks are installed as lining, the differential expansion of each block in different directions causes them to press tightly against one another, forming a seamless monolithic structure.
Ceramic fiber castable is a paste‑like, amorphous refractory material. It uses low‑slag‑ball‑content blown fiber wool as the aggregate, combined with appropriate amounts of binders, refractory fillers, and additives. This product features low bulk density, low thermal capacity, low thermal conductivity, high strength, and excellent gas tightness, making it widely used for linings in medium‑ and low‑temperature thermal equipment and for movable furnace covers. It can also serve as an insulating material in high‑temperature kilns, offering superior thermal insulation performance. The material exhibits excellent workability, and after application, it provides a monolithic furnace wall with enhanced structural integrity, making it particularly well suited for complex‑shaped linings.
Fiber spray lining is a ceramic fiber application technology that has evolved from traditional ceramic fiber‑based techniques, drawing on the spray‑application processes used for refractory powders and granules. In this process, ceramic fibers are treated with specialized spraying equipment; high‑pressure air conveys the processed fibers to the spray nozzle, where they are uniformly mixed with an atomized binder emitted from nozzles surrounding the spray head, before being applied to the working surface to form a sprayed ceramic fiber lining. Factors influencing the performance and effectiveness of ceramic fiber spray coatings include the content of slag balls in the ceramic fibers, fiber length, the uniformity of binder coating on the fiber surface, the design of anchoring elements, and the preparation of the substrate surface.
