支持される。2. Description of the Related Art Conventionally, as a zinc plating furnace for immersing pipes / steel frame structures, etc. in molten zinc and performing zinc plating treatment on the surface thereof, a plating tank for holding molten zinc is formed by a steel plate for a zinc kettle and melted. A burner is used on the furnace side wall to maintain the zinc temperature at a set point of, for example, 450 degrees. When the liquid depth of molten zinc increases and the steel plate plating tank cannot withstand the liquid pressure, the tank wall is supported by the furnace frame from the furnace frame.

て接触し、セラミック槽を衝撃で破壊することがある。However, when the steel sheet forming the plating tank is in contact with molten zinc for a long time, there is a problem that it reacts with molten zinc, is corroded, has holes, and has to be replaced. To solve this problem, it is possible to form a plating tank with a ceramic that does not react with molten zinc, but when the material to be plated is hung by a crane and immersed in molten zinc, it accidentally contacts and the ceramic tank is impacted. May be destroyed.

被鍍金材料に適用することが出来ないことである。The problem to be solved is that, although there is a demand for a tank having a large liquid depth, conventional steel plates cannot react with a large amount of liquid pressure due to corrosion with molten zinc. In addition, ceramic materials are vulnerable to impact and cannot be applied to large materials to be plated.

The side wall of the plating chamber 3 is surrounded by the steel plate frame 2. At least one inflow port 10 and at least one outflow port 11 connecting the plating chamber 3 and the heating chamber 4 are provided above and below the intermediate partition wall 8 and the steel plate frame 2. A plurality of immersion tube burners 5 are arranged over substantially the entire length of the heating chamber 4.

金材料を溶融亜鉛７に浸漬し、その表面に鍍金する。The operation will be described. An appropriate amount of zinc is charged into the heating chamber 4 and heated to a set value by the dip tube burner 5 to dissolve the zinc and prepare molten zinc 7. Then, the circulation pumps 6 and 6 are activated to forcibly circulate the molten zinc 7 between the plating chamber 3 and the heating chamber 4 via the outflow port 11 and the inflow port 10. In such a state, the material to be plated in the plating chamber 3 is immersed in the molten zinc 7 and the surface thereof is plated.
【００１０】なお、浸漬管バーナー５の存在する高温部
には鋼板が無いので、加熱室４が長期の使用に耐える。Since there is no steel plate in the high temperature portion where the immersion tube burner 5 is present, the heating chamber 4 withstands long-term use.

When the material to be plated is transported, even if it accidentally hits the side wall of the ceramic tank 1, the steel plate frame 2 is interposed, so that the ceramic tank 1 is not damaged. Further, since the intermediate partition wall 8 receives liquid pressure from both sides even if the liquid depth is increased, it does not deform, and even if it reacts with the molten zinc 7 and is corroded, there is no liquid leakage for a long time. Can be used for.
