DEVICE FOR REMOVING LIQUID FROM SURFACE OF MOVING STRIP

摘要

PURPOSE: To remove residue without damaging strip surfaces by specifying the ratio of the distance of a slot nozzle from a strip and the width of a slot to a specific value and arranging a suctional removal gap at a distance of the specific ratio from nozzle spacing intervals upstream of the line of impingement of a gas jet. CONSTITUTION: A slot nozzle 3 which orients the jet opposite to a strip traveling direction L and orients the jet to the strip surface at an angleβfrom 45 up to 90 deg. is arranged across the strip traveling direction L. The ratio of the distance (h) of the slot nozzle 3 from the moving strip B and the width (s) of the slot is set at a range of h/s=2 to 10 and the outflow velocity of the gas jet to be blown onto the strip B is set at a range of 0.3
