Since 1968 wire rod and rebar qualities have been produced at Badische Stahlwerke (BSW). Two production lines with EAF, LF and casters are used to produce the billets from scrap. In two rolling mills the billets are rolled to wire rod and rebar. The main aim of BSW was and is the most efficient Operation of the plant for the effective production of these basic steel grades. In this article results of operational trials and the interaction of process parameters at the EAF are shown.

Synopsis: In 1968, production at the Badische steel plant started with a plant capacity of 300.000 t. Now, approx. 50.000.000 t and 630.000 heats later, the plant has reached an output of more than 2 Mio.t finished product per year. The improvement of the processes at Badische has therefore a 45 year old tradition. The combination of engineering at BSE and steel production at BSW leads to one of the most efficient mini mills worldwide. The plant is operated with reliable equipment by well-educated, trained, and motivated people - this is our "Badische Philosophy". And this is the foundation for a successful steel production with high productivity and low costs. BSW operates two AC arc furnaces with 102 t tapping weight and 75 MW average power input leading to an average tap-to-tap-time of 41 min. Two ladle furnaces prepare the heats in 20 min only; casting is done via eleven strands on two casting machines. With more than 70% of hot charging the billets are rolled in a wire rod and rebar mill. Chemical energy input and optimization of the EAF process with chemical energy tools for faster melting and refining have continuously gained in importance in the steel production process. The aim worldwide is to produce with low energy consumption at low costs and with a low impact on the environment. Chemical energy tools have been in use for 30 years now - from door lances to combined systems with side wall tools and injection of solid agents - to create a more homogeneous melting and heating. Results of different operational tests at the BSW arc furnaces are displayed and discussed. Our aim is to look into the details and thus optimize the operation.

The increased use of oxygen in electric steelmaking has led to tremendous improvements with respect to electrical energy consumption and P-ON time in the last 40 years. The ongoing developments of BSE burner technology resulted in the highest efficiency and maintenance friendly equipment coupled with high reliability. The latest installation of the VLB system at North American Höganäs has improved the energy consumption by 6 % and the P-ON time by 7.6 % with a lower gas consumption as compared with previous results. At Outokumpu Nirosta Bochum BSE installed the second chemical energy package at a stainless steelmaking plant within two years. The energy consumption could be reduced by 4 % together with a 46 % reduction of refining oxygen due to higher efficiency. Additionally the electrode consumption was reduced by 9 %. Since the end of 2012 BSW has been testing a new burner technology at its own steel plant. The movable VLB continues in operation since October 2013 and the first experiences are promising. The technology enables a higher efficiency during burner mode due to an improved heat transfer to the scrap. The tilting mechanism results additionally in a further reduction in refractory wear. The first practical results are expected for publication the second half of 2014. © 2014 by AIST.

The increasing energy demand of the steel industry and the consequent increase in prices are pushing the steel producing companies to develop new solutions. Tailor-made energy recovery technologies, especially for steel mini-mills, will be a new part of activities of Badische Stahl Engineering (BSE) in the field of its environmental services. In addition to the energy recovery technologies, BSE is investigating together with the German Aerospace Centre (DLR) different kinds of energy storage systems for mini-mills.

With increasing costs for energy and CO2 emission certificates the optimisation of the furnace with respect to productivity is not always the objective. Rather, a more complex view is required which involves market conditions, like steel demand, availability of raw material, local conditions, etc. Moreover an efficient production and use of materials and tools is essential. The tests, which have been described in this paper, should show the interrelation of parameters and their impact on productivity, yield and consumption figures.

Analyzing the scrap yard logistics and operation methods is very likely to bring to light neglected potential for improvement and possibilities for cost savings at virtually every steel plant around the world. When looking for the optimal layout of a scrap storage facility or when comparing different layouts, various criteria have to be considered. The scrap storage capacity is limited by the size of the bays. Therefore, plants often build scrap bunkers. For smaller amounts of scrap, also delivery by truck is possible. But in that case, it has to be taken into consideration that the scrap bay is accessible by truck only at the front sides. A high degree of coordination between the crane drivers and the drivers of the towing vehicles or pallet carriers is needed, which may lead to delays. Also certain environmental issues have to be taken into account. Eventually, every steel plant has its particularities. These have to be taken into consideration when evaluating a layout and its ability to serve a highly productive steel plant.

The usage of burner systems in the electric arc furnace is state of the art. The latest generation of Badische Stahl Engineering's burner technology is the tiltable Virtual Lance Burner (VLB), which was tested at Badische Stahlwerke electric arc furnace no. 2 at the end of 2012. The new system allows to tap new, not yet realized potentials. The paper describes practical experiences with the new tiltable, patented VLB together with the new cooling box design.

The German minimill group Badische recognise the workforce to be the driving success of a plant's performance, people contributing 80% of productivity gains with only 20% attributed to investment in equipment. This article reviews their internal and external training philosophy.

The number of detected radioactive sources is increasing year by year. The question is not if there will be an incident with radioactive sources, the question is: when will it happen? In our opinion there is only one way to react to such a threat, which is a holistic concept consisting of three parts: Reliable measuring concept to detect radioactive contamination as early as possible. Emergency concept with defined procedures for any occasion. Continuous training of personnel.

Consulting projects at steel-making facilities always have to take into account the human resource side and the organizational side of the company to be analyzed. Maintenance is a centrally controlled business unit. There are several obstacles to this organizational form. First of all centralized maintenance organizations in practice often operate as profit centers creating a conflict of interest between production and maintenance. The operational part of this maintenance organization structure is the strong link between the maintenance and production teams. The central steering by the superintendent Maintenance+Engineering needs to make sure that there is clear task sharing. The central Maintenance Competence Center (MCC) takes care of super-ordinate functions and specialized tasks of maintenance. It belongs to the strategic part of the organization.
