Aspiration to reduce production costs of rolled products extorts a need to minimize energy consumption as well as the quantity of rolling stock. Direct rolling implementation without heating thin steel ingots is one of ways to achieve this objective. The work presents assumptions of integrated process called AST – Arvedi Steel Technology, in which rolling strips proceeds directly after ingot output from the casting machine. A main aim of this concept is to eliminate the reheating process by a maximum use of heat contained in the liquid steel. The most important advantages of this process compared with the conventional are: a huge energy consumption, pollutants reduction as well as the entire technological process and production line reduction. Moreover, a needed time to produce flat products of liquid steel is only 15 minutes. AST integrated process is supposed to appoint new directions in the production processes of steel strips.
