Novel Technology of EMD-EMC for OFC Processing

A novel technology of electromagnetic deoxidization (EMD) & electromagnetic continuous casting (EMC) for quality oxygen-free copper (OFC) processing was presented and industrial experiments and the production of OFC with this technology were completed. The results it is show that using the reasonable electromagnetic stirring in melting furnace and mould of continuous casting, the billet and/or slab of quality oxygen-free copper can be processed. The production is non-vacuum, continuous and low cost, and the material characteristics, such as the structure and the physical and mechanical properties, is over that of ones made by the traditional production. Also show that in above technology the optimization of electromagnetic stirring is very important for the ability of deoxidization from molten copper in the OFC processing, and to match the parameters, including the electromagnetic field, the mould and the casting technique, is also important for the structure, quality and characters of the billets and/or slabs.
