Abstract

PURPOSE: To produce a cold rolled steel of superior surface glossiness by measuring the finish surface whiteness of a pretreated hot rolled coil and controlling the concn. and temp. of a pickling soln. and passing speed in the pickling treatment for said coil.
CONSTITUTION: A hot rolled stainless steel coil 4 from a coil let-off machine 2 is introduced and immersed through a shot blaster 6 into a pickling vessel 8. After pickling vessel 8. After pickling, the coil 4 is coiled with a coiler 10. A coil whiteness detector 12 is provided between the vessel 8 and the coiler 10. The signal detected with the detector 12 is inputted via an amplifier 14 to a control panel 22. The detected signals of a concn. and temp. detector 16 for pickling soln. and a passing speed detector 20 are also inputted to the panel 22. In the panel 22, comparison and operation are accomplished according to set programs, and the outputs from the panel 22 are fed to a pickling soln. supplying and heating device 18, and a passing speed regulator 24, by which either one or two of the supply rate of pickling soln., the quantity of heating and the passing speed are controlled simultaneously so that they are kept within the range of adjusting programs.
