Title:
ROLLING MILL FOR PRODUCING ANGLE STEEL FROM HOOP STEEL AND METHOD FOR ROLLING ANGLE STEEL USING THE ROLLING MILL
Document Type and Number:
WIPO Patent Application WO/1996/002333
Kind Code:
A1
Abstract:
The present invention relates to a rolling mill for producing angle steel having superior surface properties and a small outer radius at a corner portion and a rolling method using the rolling mill. The rolling mill according to the present invention is a mill in which a heating device for heating running hoop steel, a universal mill having disposed thereon a pair of vertical rolls each having a slot pass formed in a surface thereof and a pair of horizontal rolls one of which has a slot pass formed in a surface at the center thereof and a group of double pass mills are closely disposed. It is possible to dispose a directly energized heating device (H2) as a heating device. Since the thickness of a central portion of the hoop steel is rolled to a great extent by means of the universal mill, an angle product can be rolled out of hoop steel whose thickness is equal to a flange thickness of the angle.
