Abstract Siemens VAI is able to offer a comprehensive suite of automation packages for iron- and steelmaking plants including continuous casting machines. Reliable solutions for power supply and drives as well as innovative technological packages, process control and process optimization systems enable smooth production and the intelligent use of energy and raw materials.
The decisive factor for cost-efficient and optimized control of the iron- and steelmaking process is our technological knowledge in the provided packages that have proven to ensure an optimum solution for small revamps as well as entirely new production units.
Expert systems for blast furnace and sinter plant have repeatedly demonstrated to cause a reduction in energy consumption and allow the utilization of low grade raw materials such as iron and coke fines. Optimization packages for steelmaking enable cost optimized input of scrap and alloying materials, resulting in very short payback periods. On continuous casters a variety of innovative and proven technological packages as well as models immediately provide quality and productivity improvements. Due to the modular design of the SIMETALCIS components it is possible to install such packages also as stand-alone versions or embedded into existing environments.
This paper presents the comprehensive spectrum of proven and cost-effective Siemens VAI electrics and automation solutions, customized to the requirements of the individual steel producers.
For the processes depicted in the figure below fully integrated automation systems as well as modular packages can be provided, e.g.:
• Process control, i.e. basic automation systems for sequential and closed loop control
• Technological control systems
• Process optimization packages
• Production planning system MES
• Energy management system EMS
• Computer based quality control systems
