Abstract

PURPOSE: To properly regulate the degree of pickling in accordance with a change in the passing speed of a strip, etc. by arranging spray nozzles in plural steps in the longitudinal direction of the strip and making arbitrary steps of spray nozzles openeable and closable.
CONSTITUTION: A strip S is introduced into a spray pickling apparatus 2 from an annealing furnace 1. The apparatus 2 is provided with plural couples of spray nozzles 4-1W4-4 at both upper and under sides of the strip S. For example, the nozzles 4-1W4-2 are closed, and the strip S is pickled with the nozzles 4-3, 4-4. During this time, when the thickness of the strip S is reduced, or the kind of steel is changed, the annealing time is shortened, and the passing speed of the strip S is increased. In this case an instruction is given to a controller for the nozzles 4-2, and an on-off valve 6 is opened with a solenoid valve to carry out pickling with 3 steps of nozzles. Thus, desired descaling can be performed.
