| description | PURPOSE:To improve pickling efficiency and to carry out stable operations by utilizing waste acids with the jet pickling method and device which pickles a steel strip by a jet pickling system in plural pickling chambers. CONSTITUTION:This jet pickling equipment has the picking chambers 2-1 to 2-3 and circulating tanks 3-1 to 3-3 for supplying acid solns. respectively to the picking chambers 2-1 to 2-3 and pickles the steel strip 1 by projecting the acid solns. from the circulating tanks 3-1 to 3-3 in a jet state to the surfaces of the traveling steel strip 1 in the respective picking chambers 2-1 to 2-3. The waste acids from the circulating tank 3-1 on the extreme downstream side is charged into the circulating tanks 3-1 to 3-3 in accordance with the results of the measurement of the acid concns. in the circulating tanks 3-1 to 3-3, by which the steel strip is pickled while the acid concns. of the circulating tanks 3-1 to 3-3 are adjusted. |
