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 seven-zone mesh belt furnace running at 1120 °C can hold ±3 °C across the belt and still ship parts with inconsistent hardness, because the dew point in the delubrication zone drifted after the belt speed was raised. That is the nature of powder metallurgy: the furnace is not a box that gets hot, it is a chemical reactor with a conveyor attached. The short answer: select a powder metallurgy furnace by the process window it must hold — delubrication profile, atmosphere quality, sintering tempe...
