Casthouse Engineering and Technology AG (hereafter CETAG) of Switzerland is a supplier of cast house process know-how and equipment servicing the worldwide aluminum industry. Our focus is not only on a single activity or piece of equipment but on the evaluation and improvement of complex cast house operations. Close cooperation with customers, experts and institutions allows us to continuously develop and improve innovative process technologies. CETAG offers the following services: Cast House Engineering and Consulting CETAG provides studies, equipment evaluation reports and services to optimize existing production processes or plants. Examples of our services include preparing a feasibility study for a new cast house or identifying measures for optimizing operations (e.g., to increase energy efficiency of a melting furnace). Dross Processing Technology CETAG is a supplier of a well-established dross cooling technology. This allows for cooling of dross to temperatures < 100° C within minutes. The quick and gentle process assures that a large portion of the “free” aluminum contained within the dross will be saved from oxidation and available for further recovery. Simultaneously the dross is reduced to a granulate, allowing for easy handling during further processing. In addition to cooling dross, the system might also be used to cool down bath / cryolite from the pot rooms. Part of our evaluation process involves examining existing equipment and preparing recommendations on how production processes and equipment can be improved to minimize metal loss and the amount of dross created during the melting process.
