Abstract

PURPOSE:To manufacture steel sheets having a high cleanness, by jetting a dehumidifed gaseous substance at high pressures against the front and back surfaces of a steel sheet just before it is fed to the temper rolling pass, on purpose to remove the carbonized smudged powder stuck upon the surface of steel sheet. CONSTITUTION:In the space isolated by the housing 4 from the external space, the jet nozzles 1 are arranged on the feed-in side of the temper rolling mill T so as to point at the front and back surfaces of the steel sheet S. A gaseous substance such as air, etc., which is previously freed from dusts, etc., by the dust remover 2 and is dehumidified and cooled by the dehumidifier 3, is jetted from the jet nozzles 1 at >=50kg/cm<2> high pressures; hereby, the smudges residing in the dull spots, etc., of the steel sheet S are blown off so that the surface of steel sheet is cleaned, and thus cleaned steel sheet is immediately processed by the temper rolling pass.
