Abstract：With the continuous promotion of automotive lightweight strategy, the application of lightweight materials aluminum alloy plate has become the focus of automotive lightweight research and development, and continuous casting and rolling technology is one of the more advanced technologies in the production of automotive body aluminum plate. By collecting Derwent Innovation Index(DII) international patent database, the patent database if Chester(such as Proquest Dialog) involved in continuous roll casting production of aluminium alloy car plate patent, using Thomson Data Analysis software(Thomson Data Analyzer) mainstream intelligence analysis tools such as car plate of continuous cast-rolling production technology in the global development present situation, trend and main technical direction and Alcoa’s continuous cast-rolling aluminium alloy production car plate patent development trend is analyzed.
