Compound Fiber Module Block for Industrial High Temperature Furnace Lining Material
Introduction
NC Compound Fiber Precast Block is an all-fiber kiln/furnace lining material developed by our company for high-temperature industrial kilns and furnaces . Adopting special production techniques, it is made of fibers of different temperatures compounded according to their different temperature conductivity grades. Additionally, the block is equipped with embedded anchors so that it is both lightweight and low in density, making it an ideal all-fiber furnace lining material for high-temperature kilns and furnaces in terms of cost, energy, life service, and weight.

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...
