Description
Ceramic fiber modules are manufactured through a process of needle-felting ceramic fiber insulation blanket followed by further processing. This process results in ceramic fiber modules with uniform density and no gaps. These modules are easy to install and have strong mechanical resistance. Additionally, their excellent thermal insulation properties can bring high energy efficiency to high-temperature industries. Ronghua Refractory can customize exclusive products for partners according to their construction conditions and application fields.
Key Features
High Temperature Resistance: They can withstand high temperatures up to 1000℃ or even higher, maintaining stable performance in high - temperature environments, suitable for use in various industrial furnaces and high - temperature equipment.
Low Thermal Conductivity: With low thermal conductivity, ceramic fiber modules can effectively reduce heat transfer, playing a good role in heat insulation and energy saving, and helping to improve the thermal efficiency of equipment.
Excellent Thermal Shock Resistance: They can resist rapid changes in temperature and are not prone to damage due to thermal shock, which ensures their reliability and durability in applications where the temperature fluctuates frequently.
Low Heat Capacity: The low heat capacity of ceramic fiber modules helps to reduce energy consumption during temperature rise and fall, enabling faster heating and cooling of equipment and improving production efficiency.
Easy Installation: They can be directly fixed on the anchor bolts of the furnace shell steel plate, and the installation process is quick and convenient. In addition, since the anchor bolts are set on the cold side of the wall lining, the material requirements for the anchor bolts are reduced.
Application of Ceramic Fiber Module
Ceramic industry: tunnel kiln, shuttle kiln, roller kiln.
Petrochemical industry: atmospheric pressure furnace, converter, coking furnace, cracking furnace, heating furnace, flue, etc.
Steel industry: ladle cover, heating furnace, annealing furnace, hood furnace, stepping furnace, hot air pipes and pipes, etc.
Environmental protection and energy saving industry: waste incinerator, RTO waste gas treatment furnace, SCR environmental protection catalytic furnace, etc.
