The main raw materials for Rongsheng’s ceramic fiber refractory products are clay clinker, bauxite, alumina, and silica sand. Rongsheng ceramic fiber refractory materials are usually divided into three categories according to their composition and use temperature: ordinary ceramic fiber products, containing Al2O3 46% ~ 48%, SiO2 52% ~ 53%, and use temperature 1000 ~ 1200℃. High-alumina ceramic fiber refractory products, containing Al2O3 56% ~ 64%, SiO2 35% ~ 44%, and use temperature 1200 ~ 1400℃. Chromium (Cr2O4, 4%) and zirconium (ZrO2, 15%) ceramic fiber refractory materials, use temperature 1300 ~ 1400℃.

Advantages and Characteristics of Rongsheng Ceramic FiberProducts

Ceramic fiber refractory fiber products have many characteristics and advantages. Rongsheng ceramic fiber products have the characteristics of high-purity Al2O3-SiO2 glass materials and fiber materials. It has good heat resistance, lightweight, good thermal insulation, small heat storage, elasticity, good resistance to mechanical vibration and thermal shock, and excellent electrical insulation and sound absorption properties.

• Heat resistance: high refractoriness, can be used at 1000~1450℃.
• Erosion resistance: good chemical erosion resistance.
• Good electrical insulation performance.
• Thermal insulation: thermal conductivity is about 1/3 lower than the best insulation brick
• Good elasticity and softness.
• Low volume density.
• Small heat capacity, 1/4 of lightweight insulation brick.
• Thermal shock resistance: no damage caused by thermal shock.
• Good resistance to mechanical vibration.
• Sealing: no need to consider expansion joints.
• Sound insulation: within 30~3000H/s, it has excellent sound absorption performance, better than many ordinary sound-absorbing materials.

The relationship between thermal conductivity and volume density of ceramic fiber refractory fiber. Ordinary thermal insulation materials have low volume density and low thermal conductivity. However, ceramic fiber refractory fiber is different. Due to the great influence of radiation heat transfer, the thermal conductivity decreases as the volume density increases.

Application of Ceramic Fiber Refractory Fiber Products

Ceramic fiber refractory fiber raw cotton can be directly used as a filling material for high-temperature insulation, but the most commonly used are various refractory fiber products made by different methods. Types of aluminum silicate refractory fiber products, among which refractory fiber blankets, paper, vacuum-formed products, and fiber spray coatings have the largest uses and usage.

• Ceramic fiber blanket: wool-like products.
• Ceramic fiber felt: soft plate-like products containing organic binders.
• Ceramic fiber cloth: cloth products woven with fiber threads.
• Ceramic fiber rope: woven and twisted rope.
• Ceramic fiber paper: paper products containing organic and inorganic binders.
• Ceramic fiber board: block products or hardboard products containing organic and inorganic binders.
• Special-shaped ceramic fiber products: products of various shapes containing organic and inorganic binders. (Rongsheng manufacturers support customized sizes and shapes of ceramic fiber boards.)
