Ceramic Fiber Cotton
Introduction
NC ceramic fiber cotton is produced by melting the very pure raw materials at high temperature, taking advantage of the spun or blowing method with characteristics of stable chemical performance, resistance to most erosion of physical properties like refractoriness and insulation, keeping the same when meeting with oil, water, or steam. Ceramic fiber blanket/felt/board/paperlcloth/rope, and other ceramic fiber products can be produced in bulk through further processing.
Characteristics
NC ceramic fiber cotton is a kind of insulating material which has these characteristics, such as light-weight, antioxidation, low thermal conductivity, softness,
anti-corrosion, low heat capacity, sound insulation, and so on.
Application
Flling sealing and insulation at high temperatures(kiln car,pipeline,kilndoor,etc.);
Composite material in the fiber industry(friction plate,etc.);
Expansion joint filler material for firebricks and castable;
Filler for short-term insulation;
Thermal insulation filling material for small corners;
Raw materials for further processing.

A 20-tonne Acheson graphitization furnace can hold full power for 24 to 40 hours and then need five to seven days of cooling before anyone opens it. Peak temperature is the headline number, but cost per tonne is decided by three quieter things: the furnace type, the condition of the insulation, and the shape of the power profile. Two shops running the same 2800 °C schedule can differ by 30 percent in kilowatt-hours per tonne. The gap is usually not the transformer. It is compressed graphite fel...
