<p>The invention relates to a method and suitable arrangement of apparatus used sequentially to produce light gauge steel strip. The feedstock is hot rolled steel strip (< 10 mm). It is intented as an upgrade to an existing process route comprising either a continuous casting and hot rolling or thin slab casting, homogenising and hot rolling. It's ideal usage is production of ultra light gauge strip of less than 1 mm thickness. Strip exiting the existing process is cooled at a predetermined rate before coiling at a downcoiler (3) located part way down the existing runout table. The coil is rapidly transferred to an adjacent position where it is paid off and rolled in a high reduction stand (7), preferably using lubrication with the stock under tension. The temperature may be chosen to roll in either the austenitic, austenite + ferrite or ferritic region. The strip is then cooled at a prescribed cooling rate prior to being recoiled (12).</p> |
