A furnace system for processing carbon fibers

| By Chemical Engineering

The carbon-fiber pilot line consists of an oxidation furnace, carbonization furnace and a graphitization furnace, The four-zone oxidation furnace operates at 325°C for stabilizing precursor fibers, and has a connecting two-step system for carbonization and graphitization at the required temperatures (low temperature up to 1,050°C, high temperature up to 1,600°C, or 1,800–2,000°C optional) and dwell times. The necessary gas supply is in between. — Linn High Therm GmbH, Eschenfelden, Germany
