Ceramic Fiber Module

RONGSHENG ceramic fiber module use the enhanced H-type anchors, which have greater strength, closer to the cold face. It can make sure the strength in high temperature. The fixed link was welding together with the high quality heat-resistance steel and stamping butterfly plate. The two round fixed link were embedded in the module system, enlarged the bearing area and ensured the firm of anchor system.

Characteristics

Low bulk density,low thermal conductivity.
Resistance to heat-shock, ability to resist the scouring of airflow.
Excellent mechanical strength ,built-in anchor, safety performance.
Easy to install. after installing the lining form a seamless space, good insulation effect.

Application of Ceramic Fiber Module

Ceramic Industry:Tunnel kiln, shuttle kiln, roller kiln.
Petrochemical Industry: Atmospheric furnace, transforming furnace, coking furnace, cracking furnace, flue etc.
Iron and Steel Industry: Ladle cover, annealing furnace,rotary furnace,bell furnace,walking beam furnace，hot air and flue pipes etc.
Green energy industry：Waste incinerators, RTO exhaust treatment furnace, SCR environmental catalytic stove etc.

Calcium silicate boards applications

Calcium silicate boards are used as heat preservation material for thermal tubes, industrial furnaces and kilns, the application industries cover power plant, chemical industry, metallurgy, shipbuilding industry and so on. Calcium silicate board is used as fire-proof and heat insulating material for buildings and apparatus. The insulating lining of high temperature drying kiln and tunnel kiln car working table is also made by calcium silicate boards. The two sides of calcium silicate board can be adhered with plastic decoration board, plywood, asbestos cement board and so on to form composite board, which has the function of decoration and fireproofing, as well as sound insulation.
