な合金化がなされるような対策が採られている。2. Description of the Related Art In the manufacturing process of hot-dip galvanized steel sheet, an alloying treatment is carried out by heating a steel sheet immediately after galvanizing in an alloying furnace. This alloying process has a problem that alloying failure is likely to occur in the vicinity of the steel plate edge and uniform alloying in the plate width direction cannot be achieved. For this reason, a measure is taken such that an edge burner is arranged on the inlet side of the alloying furnace to locally heat the strip edge, which is likely to cause alloying failure, so that uniform alloying in the plate width direction is achieved. ..

熱量を最適化する方法は確立されていない。However, the local heating amount in the vicinity of the edge by the edge burner is determined by the operator visually judging the alloying state of the steel sheet surface on the exit side of the alloying furnace, and based on this judgment. At present, what is being done is that the method of quantitatively and objectively measuring the quality of the alloying treatment and optimizing the heating amount of the edge burner has not been established.

きな原因となっていた。As described above, conventionally, the evaluation of the uniformity of the alloying treatment in the plate width direction depends on the visual judgment of the operator, so that the optimum amount of burner heating is determined by the operator. It is necessary to determine by trial and error, and therefore it is inevitable that alloying failure will occur in the vicinity of the edge until the optimum amount is determined, and in addition, edge burner positioning is performed manually. In this case, since the operator needs to perform the positioning of the strip when changing the strip width or meandering, two operations are required at the same time, which is a major cause of yield reduction.

ものである。The present invention has been made in order to solve the above-mentioned problems, and in the alloying treatment after hot dipping, it prevents alloying defects that occur in the vicinity of the strip edge and prevents alloying in the plate width direction. An object of the present invention is to provide an apparatus capable of obtaining an alloyed plating strip that has been uniformly formed.

一な合金化を可能とする装置を提供するものである。In order to achieve such an object, according to the present invention, the alloying failure near the edge of the strip occurs due to the temperature difference in the strip width direction of the strip surface immediately before the alloying furnace. Focusing on this, the temperature distribution in the plate width direction is measured immediately after plating, and the temperature distribution in the plate width direction is made uniform by individually controlling the heating amount by the edge burner based on this temperature distribution. The present invention provides a device that enables uniform alloying.
