The feature is that a hardening zone is provided with a liquid spray nozzle that spouts a cooling liquid during hardening treatment, and in the case of hardening treatment, the liquid spray nozzle in the hardening zone is operated to perform hardening and annealing. In some cases, the strip is suspended and supported by the gas jet nozzle, and the quenching zone is used as a kind of cooling zone to effectively utilize the quenching zone. The object of the present invention is to make the metal strip inexpensive, and also to prevent scratches on the metal strip by ejecting gas from the gas ejection nozzle in either case.

するようにしたものである。 FIG. 2 is a schematic diagram of the continuous heat treatment furnace 10 according to the present invention, which includes a heating zone 11, a cooling zone 12, and A quenching zone 14 is disposed between the heating zone 11 and the cooling zone 12, and hot air is blown out from the non-contact levitation conveyance means 13 of the heating zone 11, while the non-contact levitation conveyance means 13 of the cooling zone 12
Cool air is ejected from the device to heat and cool the device while it is floating.

冷却帯１２で60℃まで冷却する。 Therefore, when the aluminum strip W, which is a metal strip, is to be hardened, the aluminum strip W is heated to the hardening temperature in the first half of the heating zone 11, and then heated to the hardening temperature in the second half, as shown by the solid line in FIG. in
The aluminum strip W is maintained at 500 to 550°C and quenched in the quenching zone 14 with water jetted from a liquid spray nozzle 15 (a fog can be used) to reach a temperature of 250 to 150°C, and then cooled to 60°C in the cooling zone 12.

帯を短かくすることができる。 As is clear from the above description, according to the present invention, the quenching zone is interposed between the heating zone and the cooling zone,
During annealing of the metal strip, only the gas jet nozzle in the quenching zone is operated to function as part of the cooling zone, and during quenching, liquid is sprayed onto the metal strip from a liquid spray nozzle in the quenching zone. Hardening is then performed. Therefore, it is not necessary to provide the cooling zone with both a heating means and a cooling means as in the conventional case.In other words, the heating means is not required, which reduces the initial cost. Since it is used as part of the cooling zone, the quenching zone can be used effectively and the cooling zone can be shortened.
