HORIZONTAL HEAT TREATMENT DEVICE AND METHOD FOR PRODUCING CARBON FIBERS USING HORIZONTAL HEAT TREATMENT DEVICE

WIPO Patent Application WO/2015/002202

A1

The present invention is: a horizontal heat treatment device for continuously heat-treating by moving a continuous, flattened object to be treated (carbon-fiber-precursor fiber bundle) back and forth in the horizontal direction on multiple levels inside a heat treatment chamber, the horizontal heat treatment device being characterized by being provided with a sealed chamber (4) which is continuous from the entrance (6) side of the heat treatment chamber (2) into which the object to be treated is conveyed to the exit (6') side thereof, and in that partition plates (11) vertically delimit the sealed chamber (4) into 2-4 levels extending in the horizontal direction along which the object to be treated is conveyed; and a method for producing carbon fibers using the horizontal heat treatment device. As a result, it is possible to completely prevent leakage to the outside of poisonous gas produced inside the heat treatment chamber, and effectively exchange heat in an object to be treated (carbon-fiber-precursor fiber bundle).
