Abstract
PURPOSE:To prevent the generation of temper color by packing the spacer made of ceramic fiber at the predetermined position between the sheetlike spacer arranged at the both edge faces of cold-rolled steel sheet coil and the coil. CONSTITUTION:The cold-rolled steel sheet coil 4 is piled up via the sheetlike spacer 5 and the ceramic fiber made spacers 9a, 9b in a furnace 1. Said spacers 9a, 9b are filled at the inside within periphery at 1/3 of thickness T of the edge face or below that and ringlike from periphery of 2/3 or more of thickness T to the outer periphery. After the atmosphere in the furnace 1 is made non-oxidative, the coil is heated and annealed by the burner 6. Because the gas circulation between the coil layers is suppressed and supply of oxygen and steam is stopped by the above method generation of temper color is prevented.
