Abstract

PROBLEM TO BE SOLVED: To provide a washing device which improves washing performance by preventing a stainless strip from carrying over the oil, foreign matter, etc. floating on the liquid surface in treating vessels and sticking thereto as the washing device of a vertical type which is arranged with deflector rolls in the inlet and outlet side parts of upper parts and immersion rolls in inside bottoms and immerses and passes the steel strip into the treating liquids housed in the vessels. SOLUTION: The respective treating vessels 1, 1', 1" are constituted by disposing pairs of headers 5 which face each other across the steel strip S to be passed above the treating liquid surface Fs between the immersion rolls 3 and the deflector rolls 4 on the outlet side and are transversely provided with plural injection nozzles 6 for spraying fluid diagonally downward toward the entire width on both surfaces of the steel strip S. The fluid of the treating liquid, etc. is blown diagonally downward to both surfaces of the steel strip rising from the liquid surface and the sprayed fluid is allowed to down flow along the steel strip surfaces, by which the suspended matter sticking to the steel strip is removed. The suspended matter on the liquid surface is pressed and parted from the rising parts, by which the adhesion of the suspended matter to the steel strip is suppressed as well.

結果として洗浄性能を低下させる。In the conventional cleaning apparatus described above, since the processing tank is of the vertical type, there is an advantage that the total length of the apparatus can be shortened, but the following problems arise. That is, the deposits such as saponified products and foreign substances removed from the steel strip are suspended or settled in the treatment liquid of each treatment tank, while some of them are suspended as floating substances on the liquid surface. Since the treatment tank has a relatively small liquid surface area, the distribution density of suspended solids on the liquid surface becomes high, and these suspended solids adhere to the steel strip surface at the rising portion from the liquid surface,
As a result, the cleaning performance is deteriorated.

The injection angle θ of the injection center axis with respect to the steel strip surface is about 20 degrees,
The distance L between the spraying area (Z) and the liquid level in the tank was set to about 50 mm. The injection angle θ, the distance L, the injection flow rate, and the flow velocity depend on the purpose of the cleaning device and the steel strip. Adjust according to the type and the speed of passing it. Also, depending on the type of fluid to be jetted, the jet flow rate and the flow velocity,
The injection angle θ is set within the range of 15 to 30 degrees in order to separate the deposits on the steel strip surface and allow the jet fluid to flow down along the steel strip surface without causing diffusion or turbulence. It is preferable that the distance L from the liquid level (Fs) of the spraying area (Z) is such that the suspended liquid is pushed from the rising portion of the steel strip without disturbing the regulated liquid level (Fs) in the tank so much. 50mm ~ 10 to separate
It is preferable to set it within the range of about 0 mm.
