Thin slab continuous casting and rolling of science, technology and Engineering in one, the hot strip production in a short process production line, fully demonstrated its advanced and scientific. All countries in the world have given great attention, the thin slab continuous casting and rolling technology in recent years has make a spurt of progress of development. Compared with the traditional production process, short process can save investment, improve yield, reduce production costs, greatly reduced production cycle etc.. Thin slab continuous casting and rolling Tang Gang (FTSR) production line, the two phase after the pletion of the project, an annual output of 2500000 t hot rolled steel coil, strip thickness ~ . Product grades of carbon structural steel, quality carbon steel and low alloy steel. The production line using the Italy Danieli FTSR (Flexible Thin Slab Rolling) technology, is the first use of the technology of thin slab continuous casting and rolling production line, but also following the Algom of Canada (Algoma) Steel Corp, America Polaris factory (North Star BHP), third production lines to buy this technology. The main equipment are: continuous casting machine and two roughing mills in Italy Danieli pany, seven rolling mill, two Japanese Mitsubishi Co providing coiling machine, tunnel furnace America bricmont provided by the pany. The characteristics of the production line is the largest production of the product is thin, the thin reached , and the production line adopts many new techniques, to ensure flatness. The best part is mill, using the world39。s most advanced production of plate and strip mill PC mill. A convex lens mold with the process, the liquid core belt roller type press, equipped with automatic detection instrument of advanced puter system, realize the sequence contro l, logic control, process control, production quality control, multilevel and omnidirectional high intelligent automatic control. Can realize 3 descaling, semi endless rolling, ferrite rolling. The design for the annual production capacity of 2500000 tons of process design of thin slab continuous casting and rolling strip production line, the paper introduced Abstract III in detail the continuous casting, heating, rolling, rolling, cooling, coiling and a series of continuous casting and rolling process, emphasis is put on the rolling part. Keywords: thin slab continuous casting and rolling。 technology design。 cooling。 rolling process.
