なければならないという問題点があつた。 The honeycomb type rectifying plates 23 and 24 have the function of ejecting the atmospheric gas per processing area of each processing chamber at a constant velocity and in an isothermal state into the respective chambers 27', 27, 28, and 28'. The conventional honeycomb type rectifier plates 23 and 24 are part of the partition plate 25, that is,
Since the connecting portions of each chamber are also provided continuously, the atmospheric gases at the connecting portions of the preheating chamber 27', heating chamber 27, soaking chamber 28, and cooling chamber 28' are mixed with each other in this portion. As a result, a temperature difference occurs between each of these chambers and the atmospheric gas in other parts of the same room, which affects the heating and cooling of the material to be processed, resulting in lengthening of the furnace length and adjustment of the temperature difference between the material and the material to be processed. There was a problem that needed to be considered.

きく貢献できるものである。Effects of the Invention As described above, according to the atmosphere sealing device between zones in a heating furnace of the present invention, a passage in which no honeycomb portion exists is opened between the partition plate and the honeycomb type rectifying plate toward the atmosphere zone. The atmospheric gas ejected from this passage can form a fluid curtain between adjacent atmospheric zones, and this fluid curtain separates the atmospheric gases flowing into each atmospheric zone from the honeycomb baffle plate, so that the atmospheric gases do not interact with each other. to ensure that there is no mixed flow of
Therefore, the heat treatment of the material to be treated can be performed in each zone as planned, and the determination of the furnace length, selection of the temperature of the atmospheric gas, etc. can greatly contribute to reducing the amount of fuel burned.
