STEEL SHEET PILE ROLLING MILL

摘要

PROBLEM TO BE SOLVED: To restrain and prevent a steel sheet pile from warping in a rolling process. SOLUTION: The rolling mill of this invention cools a steel sheet pile S by blowing liquid coolant 6 to the overall width of the web W of the steel sheet pile S from liquid coolant nozzles 5 located at the inlet side of the rolling mill 1 and prevents the liquid coolant 6 from flowing down or splashing to a flange F adjoining the web W by blowing gas 8 to the flange F from gas nozzles 7. A side guide 9 is provided with a pressing unit 11 which prevents the steel sheet pile S from warping by pressing the web W of the steel sheet pile S downward. The pressing unit 11 together with the side guide 9 is moved to the width of the steel sheet pile S.
