摘要:
The present invention is: a horizontal heat treatment apparatus for continuously heat-treating by moving a continuous flat workpiece to be treated (carbon-fiber-precursor fiber bundles) back and forth in the horizontal direction on multiple levels inside a heat treatment chamber, the horizontal heat treatment apparatus being characterized by being provided with a sealing chamber (4) which is continuous from the entrance (6) side of the heat treatment chamber (2) in to which the workpiece to be treated is conveyed to the exit (6′) side thereof and that is vertically delimited by partition plates making a heat transfer zone in which 2 to 4 levels of the workpiece are transferred, among which the temperature of the workpiece transferred in a lower level is higher than the temperature of the workpiece transferred in a higher level. As a result, the horizontal heat treatment apparatus completely prevents leakage of poisonous gas produced in the heat treatment chamber, and effectively prevents energy loss.

A method for operating a continuous annealing or galvanizing line for a metal strip, uses a direct flame heating section with an upstream zone and a downstream zone. The direct flame heating section is followed by a radiant tube heating section. The metal strip is indirectly heated in the direct flame heating section. The heating of the metal strip is achieved in the upstream zone by combustion of a mixture of atmospheric air and fuel such that the temperature of the combustion gas is between 1250° C. and 1500° C., preferably close to 1350° C. and in the downstream zone, the heating of the metal strip is achieved by combustion of a superoxygenated substoichiometric mixture of air and fuel such that the temperature of the combustion gas achieved at the end of the upstream zone is maintained until the end of the downstream zone of the direct flame heating section.

An improved heat tunnel is provided for use with a thermo-forming press. The heat tunnel includes a first oven body having a heat source therein for applying heat to a web of thermo-formable material as the web is supported therein. The tunnel includes a second oven body having a heat source therein for applying heat to a web of thermo-formable material as the web is supported therein. Furthermore, the tunnel has an adjustable length tunnel body carried between the first and second oven bodies and configurable to adjust the overall length of the heat tunnel so as to realize a desired delivery of heat to a web of material being passed there through.
摘要:
A sealing apparatus securely seals the inlet and outlet of an atmosphere heat treatment furnace. A pair of elastic rolls 26 and a pair of additional elastic rolls 26 hold a metal strip so as to seal the inlet and outlet of the atmosphere heat treatment furnace which continuously performs bright annealing of the metal strip in a combustible atmosphere gas including hydrogen gas. A pair of intermediate rolls are disposed between the elastic rolls and the additional elastic rolls. The outer peripheral surface of the elastic roll is sealed by a seal plate. By multi-stage sealing, the outside air can be shut off securely from the atmosphere of the furnace.
