Summary:PURPOSE: An annealing method of cold rolled metal strips is provided to reduce potential on the surface of a strip by the suppression of reaction among cold-rolling lubricant, metal, and atmosphere. CONSTITUTION: An annealing method of cold rolled metal strips comprises following steps. A cold rolled metal strip is consecutively transferred along the transporting path in which a ramp(1) is positioned. The ramp is formed of DFI(Direct Flame Impingement) burners which heats strips. The ramp is placed vertically to the traveling direction of the strip. The DFI burners heat the full-width of the strip at the same temperature. The heat-treated strip is wound with a coil(5).
