The ReWaCEM project aims at reducing water use, wastewater production, energy use, valuable metal resource recovery and water footprint by between 30-90% in the metal plating, galvanizing and printed circuit board industry. In order to achieve these goals, ReWaCem will adopt two cutting edge membrane technologies suitable for the requirements of closed material cycles approaches and recovery concepts in metal processing industry: Diffusion Dialysis (DD) and Membrane Distillation (MD) as an integrated hybrid process. This combination of existing technologies will be adapted to fit the requirements of 4 pilot demonstration sites in representative industrial applications of the metallurgical industry in order to evaluate the accomplishment of the ReWaCEM goals. Through the evaluation of the demonstration a highly attractive technological solution for low energy wastewater treatment will be available to be entered into the large and growing market of metal processing. This market will profit significantly from the technological outcome of the innovation action, with cost savings and environmental benefits as relevant rewards. In order to maximise impact, the project consortium was selected carefully to represent all relevant stakeholders in the quadrant of end users, scientific partners, associations and decision makers and SMEs. The consortium will establish a dissemination & exploitation board that will create a substantial network of interest groups from agencies, industry, research SMEs and research centres as well as universities. The successful exploitation of the results will lead to a post project up-scaling of the technology and a step by step market introduction. Part of ReWaCEM will be to mobilise all relevant stakeholders into promoting innovative membrane solutions for industrial water and resources management, leading to the effective implementation of European directives and policies while creating market opportunities for European industry and SMEs.

Since its beginnings in the second half of the 19th century ingot casting technology has undergone a dramatic evolution. After continuous casting was introduced in the 1960s, ingot casting production has concentrated increasingly on large-dimension and niche products, which either cannot be coped with by continuous casting or are needed only in very small quantities. Downhill casting was gradually replaced by uphill casting. Refractory materials and casting fluxes have been substantially sophisticated. The quality and cleanliness of ingots must keep pace wiith the constantly growing requirements. Here modern special remelting processes are of decisive importance, as they have the potential to further improve the cleanliness of cast ingots. The smart combination of the various processes enables steel grades to be produced which, also in the furture, will make ingot casting the only choice in many applications.

Deutsche Edelstahlwerke, a leading producer of long specialty steel products, manufacture mandrel bars and supplies them to nearly all seamless tube rolling mills of the world. Approximately 5,000 mandrel bars with diameters between 50 and 350 mm are produced ready-to-use by Deutsche Edelstahlwerke every year. The manufacturing process begins with the scrap, which is melted in a 130 t electric arc furnace at the steelworks. A certain ratio of the alloying elements chrome, nickel, molybdenum, tungsten, vanadium and cobalt is required to produce the desired material properties depending on the intended purpose of the material. The machine puts the bar in constant rotation and measures the profile of the mandrel bar using an adjusting device, which runs its sensors along the bar and measures its deflection. The straightening process is then started automatically. Certain separating agents and lubricants are then applied to the mandrel bar in a spiralled manner before it is returned to the process flow.

To enhance the quality of tool steels it is necessary to analyse all stages of the production process. During the ingot- or continuous casting processes and the following solidification, material and geometry depending reactions cause defects such as macro segregations or porosities. In former times the trial and error approach, together with the experience and creativity of the steelworks engineers was used to improve the as-cast quality, with a high amount of test procedures and a high demand of research time and costs. Further development in software and algorithms has allowed modern simulation techniques to find their way into industrial steel production and casting-simulations are widely used to achieve an accurate prediction of the ingot quality. To improve the as-cast quality, several ingot casting processes of tool steels were studied at the R&D department of Deutsche Edelstahlwerke GmbH by using the numerical casting simulation software MAGMASOFT®. In this paper some results extracted from the simulation software are shown and compared to experimental investigations.
