SIMETALCIS BOF Optimization    Process optimization system for BOF converter

The BOF process optimization system is a completely integrated solution to operate the BOF converter at an extremely high efficiency and availability to produce the required quantities. The solution is particularly suitable for a wide range of operating conditions, e.g. variable scrap to hot metal ratios, minimum slag practice and varying phosphorus content.

BOF converter pulpit The challenge While demands on products and processes are ever increasing, steel producers meet capacity limits that may not least be caused by inadequate automation technology. Often, outdated automation systems supply poor optimization and insufficient documentation of steelmaking processes and thus cause high maintenance costs.

Our solution

Siemens VAI automation systems are based on decades of combined engineering, plant-building, operational, metallurgical and automation experience and are the key to high-tech BOF steelmaking for high quality products at low production costs. Siemens VAI is able to provide stable systems due to the application of their well-proven solutions. In addition, both integrated and standalone automation solutions are provided for all levels. Innovative process models which are purely based on physical and chemical principles make it possible to achieve accurate imaging of the complete BOF process. The advanced BOF optimization system determines the required charging materials as well as the oxygen volume to be blown and controls the BOF process in fully automatic mode. Furthermore dynamic process control for determination of the blow-end point is possible, either based on continuous off-gas measurement or inblow measurement via sublance. The BOF process models allow for offline tuning and simulation prior to release to the production system. Unlike other solutions, no software modifications are necessary to adapt model behavior. To round off the package, Siemens VAI provides worldwide metallurgical and automation assistance via remote links and local Siemens VAI service representatives.
