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 (<10mm). It is intended 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 1mm 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. |
