Abstract

531,685. Metals pickling. CURRAN BROS., Ltd., and CURRAN, J. June 23, 1939, No. 18337. [Class 82 (ii)] Apparatus for pickling metal strips or sheets comprises a pickling chamber through which run pipes having spraying orifices and means for conveying the strips &c. through, or supporting them as they move through, the chamber with their surfaces close to the orifice, the crosssection of the chamber being no larger than is necessary fo accommodate the spray pipes, the strips or the stationary supports or the conveyer if used and also a squeegee if such is used. In the pickling of metal strip 1, the latter is passed continously through the narrow pickling chamber 2 over pipes 6 having spraying orifices situated about one inch from the strip, and fed with acid by pipe 9 from a pump 8. The acid draining off the strip runs back by pipes 10 to a tank 7. The end plate 5 and the intermediate plates 4 of the chamber 2 are provided with slots through which the strip passes and which are provided with rollers to support the strips. The partitions 4 may serve as partitions between pickling neutralizing and/or washing chambers. The strip may be conveyed through the chamber by an endless conveyer which has a series of pointed projections on which the strip rests, such projections serving to draw off by capillary attraction acid which may have collected on the under surface of the strip. A squeegee may be situated under the strip to remove any acid adhering to the under part of the strip. A fume stack 11 is provided at one end of the chamber.
