The trend that thin gauge hot rolled strips replace cold rolled strips is expanding gradually, more and more ultra-thin gauge hot rolled strips have been applied in diffirent sub-industry,although these are hard to produce. The following issues have been solved,such as slab centring,wedge deviation,camber,resistance of deformation improved by narrow range of chemistry and temperature control,slab profile check out,and slab temp. homogenization and optimization of process and equipment on CSP line in Zhujiang Steel;The pitting on strip surface has been controlled by means of rational ambience and working ststus of roller inner furnace,cooling adjustment of work rolls and logistic rolling scheme.A patent on rolling mill operating method was applied for reducing cobble and crimping accident and waves defect;The technology package including new pattern, material and convexity of work roll in F6 has been researched and used to solve the problem of cobble accident,collapse and centre waves during ultra-thin gauge check plate production.The above research results have been applied successfully to high ratio of ultra-thin gauge hot rolled strips production at Zhujiang Steel, the proportion of plain steel strips of h=1.0mm~1.35mm is more than thirty percent, the proportion of check plate of h=1.0mm~2.0mm is more than seventy percent, including h=1.0mm~1.8mm check plate of twenty-eight percent.
