A large amount of heat is required to heat the alloying furnace to carry out the alloying process, and conventional equipment requires both furnaces to be installed independently and operated completely separately. As a result, a great deal of thermal energy has been wasted.

図示しない次工程に導出される。The present invention provides a tamping equipment that improves the problem of heat generation, and includes a waste heat recovery device installed at the flue of the plating furnace and at the outlet of the alloying furnace. The heat is recovered as hot air, and the hot air is passed through a blower to a temperature of 1lI.
It is designed to be fed to the inlet of the alloying furnace through the II device. 'Now, the example equipment shown in FIG. 1 will be explained. In the figure, (1) is a plating furnace, and in order to form and maintain the plating metal in the plating pot (1 &) installed in it in a molten bath state, fuel is burned and broken, and the OI
It is blown into the atmosphere from the chimney (6) through the I-Gas flue (8). Copper strip to be plated (8) enters the metal bath from diagonally above indicated by the butterfly arrow (K), changes direction with the zinc roll (1b) placed in the same bath, and pulls in the ttx vertical direction. It is lifted up, passes through the alloying furnace (3), and is continuously led out to the next step (not shown).

中直接導管（９ａ）の取入口が廃熱回収器に相当する。In such ordinary plating equipment, there are two possible methods of waste heat recovery W (2) provided in the flue (8) depending on the degree of contamination of the combustion gas. That is, plating furnace (1)
When the fuel is light oil or gaseous fuel, the combustion gas is also clean and does not contain soot and dust, so to recover the waste heat, it is sufficient to collect a part of the combustion exhaust gas directly from the flue. The intake of the intermediate direct conduit (9a) corresponds to the waste heat recovery device.

回収器（４）もこれと同様であるから詳述はしない。In one case, the plating furnace (1) uses heavy oil such as heavy oil, and the combustion waste gas contains:
Since it contains soot dust and sulfurous gas, a tube nest or a serpentine pipe is used as the waste heat recovery device (2), and the air sent into the recovery device is indirectly heated with a blower (not shown), thereby indirectly converting it into hot air. It will be led out from the conduit (9b). The waste heat recovery device (4) used for KFR at the outlet (6b) of the alloying furnace is also similar to this, so a detailed description thereof will not be given.

の間には、温度制御回路が構成されている。In the equipment of the present invention, the hot air led directly or indirectly from the waste heat recovery device (2) through the pipe (9) and the hot air led from the waste heat recovery W (4) through the pipe (10) are (16), the guiding proa (15), the conduit (
Via 17): enters the IhA degree regulator (5). The temperature adjustment device is a device that adjusts the temperature of the hot air introduced from the pipe (17) to a temperature suitable for feeding it to the alloying furnace (3), and includes a Hekisuke burner (16) attached thereto. A temperature control circuit is constructed between the outlet pipe line (18) of the device and the burner.

The hot air whose temperature has been adjusted to the temperature required by the alloying furnace passes through the proa (21) and pipe (22) to the alloying furnace population section (3a).
) to effect alloying on the surface of the deposited metal. As described above, a part of the hot air possessed by the hot air introduced into the alloying furnace is recovered as hot air at the exit of the furnace, passes through the pipe (10), and repeats the process described above. Note that the waste gas after the heat recovery is dissipated into the atmosphere through the chimney (7).

ある。The waste heat originating from the plating furnace and the alloying furnace is recovered by the waste heat recovery device (2, 4), and the temperature is adjusted by the temperature adjustment device as hot air and circulated. Since it is reused, it is extremely thermoeconomical and can save 30 to 40% of conventional fuel consumption. In particular, the temperature required by the alloying furnace needs to be supplied as hot air 1 whose temperature corresponds to the thickness of the strip, the threading speed, and the amount of coated metal, but in the equipment of the present invention, There is an advantage that the hot air can be easily adjusted to the desired temperature using a temperature adjustment device. Conventionally, there was a tendency to unnecessarily raise the temperature of the pre-alloying furnace, but with the equipment of the present invention, it is easy to lower the temperature to the required minimum temperature, so products with a good plated surface condition can be obtained. This also improves product yield.
