METHOD FOR MANUFACTURING FLAT SHEET PILES AT MINIMIZED PROBABILITY OF BREAKAGE OF ROLLS

摘要

PURPOSE: A method for manufacturing flat sheet piles is provided to extend the life span of rolling rolls by compensatively processing a damaged rolling roll in a universal rolling mill.;CONSTITUTION: A method for manufacturing flat sheet piles comprises a first rolling step(10) for extending the web of a rolled material(1) in the longitudinal direction, a second rolling step(20) for rolling the firstly rolled material to lengthen the upper flange(b) while shortening the lower flange(c), and a third rolling step(30) for gradually bending the secondly rolled upper flange through multiple rolling processes to form loop-type interlock parts(120) bent to opposite sides at both ends of the web.;COPYRIGHT KIPO 2013
