CONTINUOUS PICKLING DEVICE FOR STEEL STRIP

摘要

PURPOSE:To prevent floating up of a steel strip and eventually to immerse the steel strip in a pickling soln. so as to improve pickling performance by disposing at least a pair of gates in a pickling cell. CONSTITUTION:>=1 Pairs of gates 12 are disposed in the pickling cell so as to sandwich the steel strip from above and below. The gates 12 has nozzles 13 worked to a cushion shape. The pickling soln. 4 is increased in pressure by a pump 17 and is supplied through a piping 15 with a valve 16 to headers 14. The soln. is sprayed in the form of jets to the steel strip 15 from the nozzles 13. A pressure pocket region 18 of a high pressure is formed to the intermediate part of the nozzles 13 by the jets of the pickling soln. from the cushion type nozzle 13 having an angle and the steel strip 5 is passed to the central part between the gates 12 by such region 18.
