Abstract

PURPOSE:To manufacture a zinc plated steel sheet excellent in the coating brightness by subjecting a steel sheet to skin-pass rolling by the bright roll of <=0.8mum surface roughness Ra and refined-rolling the steel sheet by the dull roll of 1.2mum<= surface roughness Ra<=4.0mum. CONSTITUTION:The surface roughness of a bright roll and dull roll is made within the specified range in order to improve a coating brightness by forming a fine unevenness on the surface of a zinc plated steel sheet. Namely, the unevenness of a zinc plated face is leveled by a 1st pass rolling by the bright roll of <=0.8mum surface roughness and the surface waviness reduced. Then the small unevenness of the roll surface is transferred so that the unevenness becomes reverse on the leveled steel sheet surface by a 2nd pass rolling by the dull roll of 1.2mum<= surface roughness Ra<=4.0mum. Consequently a proper surface roughness and surface waviness are given on the zinc plated steel sheet and the steel sheet of excellent coating brightness and press workability can be manufactured.
