本発明は、連通部を介して接続した直下式加熱
帯と冷却帯とからなり、加熱帯の炉内雰囲気を冷

鈍炉に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention consists of a direct-type heating zone and a cooling zone connected through a communication part, and uses the in-furnace atmosphere of the heating zone as the atmosphere in the cooling zone. The invention relates to a continuous annealing furnace for strips containing low melting point metals.

気を連通部を介して冷却帯へ供給し、この雰囲気
をクーラで冷却して、冷却帯での雰囲気として使
用していた。 Conventionally, in continuous annealing furnaces for strips containing low-melting point metals of the type described above, the furnace atmosphere of the heating zone is supplied to the cooling zone through a communication section, and this atmosphere is cooled by a cooler. It was used as an atmosphere.

気として加熱帯からの高温炉内雰囲気を使用する
ためクーラが大容量のものとなるばかりか、加熱
帯にも冷却帯からの冷却された雰囲気が連通部を
介して流入するため、加熱帯での熱効率が悪くな
るという欠点があつた。 By the way, in the above-mentioned type, the high-temperature furnace atmosphere from the heating zone is used as the atmosphere in the cooling zone, so not only does the cooler have a large capacity, but the cooling zone also communicates with the cooled atmosphere from the cooling zone. This has the disadvantage that the thermal efficiency in the heating zone deteriorates because it flows through the heating zone.

るという欠点があつた。 Furthermore, the furnace atmosphere in the heating zone contains evaporated metal generated by heating the strip, and this evaporated metal solidifies in the cooling zone and adheres in large quantities to the cooling gas jet nozzle, header, etc., causing the cooling capacity to increase. This has the drawback that not only is the performance reduced, but maintenance is also troublesome.

供することを目的とする。 In the continuous annealing furnace, the heating zone and the cooling zone are connected through a duct, and a water washing device is provided in the duct to remove evaporated metal contained in the atmosphere of the heating zone and return it to the atmosphere of the cooling zone. In addition, a gas sealing mechanism is provided in the communication section between the heating zone and the cooling zone, and the furnace pressure at the rear end of the heating zone and the front end of the cooling zone is constantly measured, and the amount of atmosphere supplied from the duct is adjusted. It is an object of the present invention to provide a continuous annealing furnace for strips containing low-melting point metals, which eliminates the above-mentioned drawbacks of the prior art by preventing mutual penetration of the atmosphere in both zones.

することができる等の効果を有する。 As is clear from the above explanation, according to the continuous annealing furnace for strips containing low melting point metals of the present invention, since the evaporated metal contained in the atmosphere of the heating zone is removed by the water washing device, the duct of the cooling zone is It does not solidify and stick to the jet nozzle or jet nozzle, eliminates the need for troublesome maintenance such as removing stuck metal, and improves furnace operation efficiency. Furthermore, since the reactor is regulated by a furnace pressure regulator and introduced into the cooling zone, the cooling efficiency in the cooling zone can be further improved and energy can be saved. In addition, the communication area between the heating zone and the cooling zone is sealed with a gas sealing device, and the atmospheres in both zones do not mix, so the thermal efficiency in the heating zone and the cooling efficiency in the cooling zone do not decrease. This has the advantage that the atmosphere in the furnace consisting of the combustion exhaust gas in the heating zone can be effectively used as the atmosphere in the cooling zone.
