・均熱したコイルを冷却帯で循環ファン２よび冷却器か
らなる冷却装置により強制力流冷却している。Conventionally, when heat-treating metal nutrig cari iVk in a heat treatment furnace that has a heating zone and a cooling zone, the coil is heated and uniformly heated to a predetermined temperature in the heating zone, and then the coil is forcibly heated in the cooling zone by a cooling device consisting of a circulation fan 2 and a cooler. Power flow cooling.
ところで、加熱帯、冷却帯を備えた前記熱処理炉に２い

は勿論、冷却水の使用量も増加して運転費が増大する。Therefore, for uniform cooling, a rectifier plate is placed above the coil.
On the other hand, in order to shorten the cooling time, it is possible to increase the capacity (air volume) of the circulation fan (in the furnace) and the capacity (cooling capacity) of the cooler. In the former case, the cooling capacity does not increase even though the power cost increases. In the latter case, the operating cost increases not only in equipment costs but also in the amount of cooling water used.
すなわち、いずれの一方法も十分な冷却時間の短縮とな

A cooling device consisting of a movable cooling box having water supply and drainage means is provided in the cooling zone, and the coil is cooled by bringing it into direct contact with the flat surface of the coil. The present invention aims to provide a cooling zone in a heat treatment furnace for metal coils that can uniformly cool the coil and shorten the cooling time.

れる。The coil W heated to a predetermined temperature (700° C.) in the heating zone 4 is charged into the cooling zone 6 by the lifting operation of the intermediate door 9 and the movement of the trolley 10 one pitch. In the coil W1 located in the cooling zone 6, the coil W1 itself is heated to a high temperature, so the cooling effect due to radiation is large, and in order to prevent the disadvantages caused by rapid cooling of the edge of the coil, First, forced convection cooling is performed at 400 to 500°C using a circulation fan.

すれ赫よい。In the above embodiment, the coil W is processed in an up-end state, but if it is a pre-processing type that ripens eggs in a down-end (horizontal) state, the cooling box 12 is placed in the cooling zone 6. It is convenient to install the circulation fan F on both side walls and install it on the ceiling 6AK.

従来の約１７２の小型のものでもよい。Furthermore, in either case, the amount of cooling water used can be reduced by controlling the amount of cooling water supplied to the cooling box 12 to be large at the beginning of cooling and to be small at the end of cooling. A # ring fan F (in some cases, a cooler and a circulation fan) is installed in the cooling zone 6 section J, and the cooling capacity is improved by using forced convection cooling using the furnace atmosphere gas. If you think about it, the circulating 7 amp cooler C may be a conventional small-sized one of about 172 amps.

来のものに比して著しく大である。As is clear from the above explanation, the cooling zone according to the present invention does not use a convection cooling method as in the conventional case, but has a cooling zone on the flat part of the coil.
Since it uses a simple mechanism to bring the water-cooled box into direct contact with the movable cage, its cooling capacity is significantly greater than that of conventional systems.
