Abstract

PURPOSE: To thoroughly descale a hot rolled steel sheet with no environmental pollution at a low cost by working the sheet through skin pass or bending and then dipping it in a soln. of NaCl.
CONSTITUTION: Tight coil 1A is uncoiled by uncoiler 2 and rolled by skin pass mill 3 at a reduction ratio of 2W15% to crack the scale layers. When the coil is reeled round coiler 4, string 6 is supplied from string reel 5 to form open coil 1B. Coil 1B is then dipped in pool 7 filled with a soln. of NaCl such as seawater, and after a predetermined time the coil is brushed and washed with water to be thoroughly descaled
