よシ出て、図示しない後工程に供給される。After the steel strip 1 at room temperature is unwound from a payoff reel (not shown), the scale that had formed on the surface of the copper strip is pickled by the acid solution 3 while running while immersed in the acid solution 5 in the acid tank 2. The descaled steel strip 1 is transferred to the acid tank 2.
It comes out and is supplied to a subsequent process (not shown).
従来の連続酸洗装置では、鋼帯は酸タンクに充満された
酸液内を浸漬しながら走行するため、次のような欠点が
あった。In conventional continuous pickling equipment, the steel strip travels while being immersed in an acid solution filled in an acid tank, which has the following drawbacks.
図示しないペイオフリールで、コイルカー巻き終了する

コイル毎に鋼帯の温度が異なる場合も同様である、
〔問題点を解決するための手段〕
本発明は、従来装置の上述した不具合を解決し、銅帯の

供するものである。A new coil is connected using a payoff reel (not shown) each time the coil car winding is completed, and the steel strip is continuously supplied to the pickling process. The type of steel strip, scale properties, etc. may vary greatly depending on the coil, and the time required for pickling differs for each coil, so it is necessary to change the running speed of the copper strip. It takes a certain amount of time to change the speed, so the steel strip that went through the pickling process during the speed change, mainly at the coil joints, was either insufficiently pickled or overpickled, resulting in poor product yield. The same is true when the temperature of the steel strip differs for each coil. [Means for Solving the Problems] The present invention solves the above-mentioned problems of the conventional device and explains how the conditions of the copper strip change. The purpose of the present invention is to provide an apparatus that immediately adjusts the pickling time to an appropriate value and improves the yield of the product.
具体的には酸タンク上方に設置された複数個のダクト内

共に、ダクト内への酸液の供給、遮断を自在に行えるよ
うにし、かつダクト内に充満している酸洗を短時間にパ
ージすることができるようにしたものでちる。Specifically, the acid solution is flowed into multiple ducts installed above the acid tank, so that a copper strip runs through the ducts, and the acid solution can be freely supplied or shut off to the ducts. It is designed to be able to purge the pickling that is filling the duct in a short period of time.

である。That is, the present invention provides an acid tank, a plurality of ducts arranged above the nucleic acid tank and equipped with an acid liquid jetting nozzle and an acid liquid purge air pipe, through which the material to be pickled passes, and an acid liquid in the acid tank. This continuous pickling device is characterized by comprising an acid liquid pump that supplies acid liquid to a nozzle in the duct, and a three-way valve installed in a pipe between the acid liquid pump and the nozzle.
本発明の連続酸洗装置においては、ダクトを複数個設置
しており、酸液を流すダクト数を変更することで銅帯の
走行速度を変えずに銅帯の酸洗時間を変更することがで
きる。In the continuous pickling apparatus of the present invention, a plurality of ducts are installed, and by changing the number of ducts through which the acid solution flows, it is possible to change the pickling time of the copper strip without changing the traveling speed of the copper strip. can.
また、ダクトへの酸液の供給を停止すると同時に、パー

流すダクトの数を容易に変、えることができる。In addition, at the same time as the supply of acid solution to the duct is stopped, air is jetted into the duct from the purge piping, and the acid solution remaining in the duct can be instantly flushed out, reducing the number of ducts through which acid solution is flowing. Can be easily changed and changed.
