de los ThinkPad roll for the adsorption and groove marks prevention

摘要

The present invention is alloyed galvanized steel sheet (GA) and galvanized steel sheet (GI) facilities combine to produce a to achieve the conversion of the strip in the direction of the sink roll provided inside the plating bath , to optimize the shape of the groove formed on the surface of the sink roll , and the roll crown dE generated by changing the LOS adsorbed to the surface of the strip and groove home mark relates to the sink roll to enhance the surface quality by minimizing the occurrence of . ; the present invention is formed in the longitudinal direction on the surface of the roll and pitch of 1.75 0.2mm in a range of adjacent acid to acid and , and the depth range is 0.2 0.05mm , 0.25 0.05mm and a bottom flat surface of the range , both side edges of the bottom flat surface is 0.3 0.1mm sink roll having a rounded groove with a groove radius of curvature in the range of provides .
