PURPOSE: A temperature correction type cooling apparatus of hot rolling rolls is provided which injects cooling water onto the hot rolling rolls and controls the cooling water injection amount of a variable injection unit so that the surface temperature of the hot rolling rolls is uniformly distributed. CONSTITUTION: The temperature correction type cooling apparatus of hot rolling rolls comprises a cooling water supply unit(5) in which a bellows pipe(5-3) is connected to one side of a connection pipe(5-2) inserted into a motor so that the bellows pipe(5-3) is connected to a supply pipe(5-4); a piling unit in which a roll piling stand(6-3) which is positioned symmetrically to the cooling water supply unit(5), and on which a chock stopper is formed is inserted into one side of the cooling water supply unit(5); a cooling water variable injection unit(7) which is positioned at the rear of the piling unit, and in which an injection pipe is connected to a solenoid valve connected to a connection pipe, and cooling water is injected by an exterior angled injection port; a roll cooling unit which is positioned at one side of the piling unit, and in which the cooling water variable injection unit(7) is inserted into thus locked to a plurality of fittings of upper and lower roll cooling pipes, and the upper and lower roll cooling pipes are inserted into upper and lower roll cooling pipe spigots of a main body respectively; and a temperature measuring and shape recording unit(9) which is positioned at the other side of the piling unit, and in which a shape recording unit assembled screw is inserted into a spigot of a main body.
