Abstract

PROBLEM TO BE SOLVED: To provide a facility used for both of continuous annealing and hot dip metal coating which produce a steel plate in the same facility by changing over the continuous annealing and the hot dip metal coating. SOLUTION: In the facility used for both of the continuous annealing and the hot dip metal coating, a bypass furnace is set to feed the steel plate from a continuous annealing furnace to water quenching without passing through a plating pot and a plating apparatus, and thus, when the continuously annealed material is produced, the steel plate coming out from the annealing furnace is prevented from contacting atmosphere and being oxidized, and this facility can be realized at a low cost.

る。SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No.
According to No. 6469, a steel sheet is used for producing a continuously annealed material without attaching the steel sheet coming out of the continuous annealing furnace to a plating pot.
A combined equipment for a hot-dip plating line for cooling in the atmosphere and a continuous annealing line is shown. However, there is a problem that the surface of the steel sheet is oxidized as it is because the temperature of the steel sheet just released from the continuous annealing furnace is high. In order to remove this oxide film, it is conceivable to add a pickling device. However, the addition of the pickling device increases the capital investment, necessitates the installation of a new wastewater treatment facility, and increases the operation load. There's a problem.

However, in order to cool the steel sheet to such an extent that the steel sheet does not oxidize even if it comes into contact with the atmosphere, the number of cooling facilities in the continuous annealing furnace is increased, and the capital investment is increased. The present invention solves the above-mentioned problems, and proposes a measure for realizing a continuous annealing and hot-dip plating facility for a steel sheet without significantly increasing the facility cost.

FIG. 1 illustrates an annealing furnace part of a facility for combined use of continuous annealing and hot-dip plating to which the present invention is applied. The steel sheet 1 is annealed in a continuous annealing furnace 2. During the production of the plating material, the steel sheet 1 passes through a continuous annealing furnace 2 and is guided to a plating pot 3 for plating, as indicated by a broken line. Then, after the plating amount is adjusted in the plating apparatus 4, an alloying treatment is performed in the alloying furnace 5 as necessary, and the alloying treatment is performed in the steel sheet cooling apparatus 6. And cooled to approximately room temperature. These series of processes are not different from general processes in the production of hot-dip plating.

通坂可能なようにバイパス装置８を設置した。During the production of a continuously annealed material, the steel sheet 1 needs to be cooled to approximately normal temperature by the water quench device 7 without passing through the plating pot 3, the plating device 4, the alloying furnace 5, and the cooling equipment 6. However, when the steel sheet 1 is exposed to the atmosphere after passing through the continuous annealing furnace 2, the steel sheet surface is oxidized. Therefore, in the present invention, the bypass device 8 is installed so that the steel plate can pass directly from the continuous annealing furnace 2 to the water quenching device 7 without coming into contact with the atmosphere.

る。The inside of the bypass device 8 is, for example, 5 to 10% H 2 -95 to 90% N 2 in the same atmosphere as in the continuous annealing furnace.
Since the steel sheet 1 is kept in such a non-oxidizing atmosphere, the steel sheet 1 can reach the water quench device 7 without being oxidized and can be cooled. Further, a plating pot 3, a plating device 4, a lane 9 are provided below the bypass device 8.
By installing the steel plate, it is possible to carry out and repair the plating pot, the plating apparatus, or the equipment installed in the plating pot during the production of the continuously annealed material, thereby improving the production efficiency.
