Title:

A CONTINUOUS CASTING AND ROLLING METHOD FOR MEDIUM PLATE

Document Type and Number:

WIPO Patent Application WO/2006/102835

Kind Code:

A1

Abstract:

A continuous casting and rolling method for medium hot strip is comprised of following steps: continuous casting, during molten steel passing through crystallizers , to form casting blanks having a section thickness of 100-170mm and a width of 900-2000mm by hydraulic oscillating, continuously bending and continuously straightening ; direct rolling, hot feeding and hot charging casting blanks by a two machine with four streams and four streams merging one technique, achieving rapid hot feeding and hot charging or direct rolling for continuous casting blanks ; roughing by a rougher with front and back vertical rolls ; finishing using raising speed rolling by a finishing mill each stand of which are provided with a device for axial shifting and bending rolls, wherein the maxium speed is 22.8m/s and the speed of rollers table is up to 5.89m/s;stream cooling using a three stages stream cooling control technique;coiling with a full-hydraulic coiler controlled by a stepping control technique . The invention provided improvements on layout, apparatus, production process etc., improving production capacity, development for kinds of product, product quality and organization of production.
