PURPOSE: A reoiling apparatus per positions of a steel strip is provided to automatically measure oil coating amount and accurately control oiling amounts per desired regions when performing reoiling due to retreatment of the surface of the strip and controlling of oiling amount. CONSTITUTION: The reoiling apparatus per positions of a steel strip comprises a support frame(10) equipped with a pair of rails(11,11') at upper and lower parts of a passage through which a strip(S) passes in such a manner that bases(20,20') are mounted on the upper and lower rails(11,11') and driven by motors(21,21') so that the bases(20,20') are slid in a width direction of the strip(S); a rack(30) which is installed at an upper base(20) and vertically ascended or descended as it is being guided to a guider(31) by driving of a pinion connected to a shaft of a motor(32); an upper detector(40) which is mounted on the lower part of the rack(30) to check oil amount coated on the upper surface of the strip; a lower detector(40') which is installed at a lower base(20') and vertically moved by movements of a cylinder(50) to check oil amount coated on the lower surface of the strip; sensors(60,60') which are installed at one side of the upper and lower detectors(40,40') to sense up and down action ranges of the upper and lower detectors(40,40'); and sensors(70,70') which are installed at both ends of the upper and lower rails(11,11') to recognize positions of the upper and lower bases(20,20').
