EMSA (Elektrode Maatskappy van Suid-Afrika) was established in October 1965 in a collaboration between Amcor and two German firms (Hoechst & Siemens). The Meyerton company produces graphite electrodes, the heating "prongs" which conduct the electrical charges that melt scrap iron to make steel. Today, EMSA is wholly owned by Ucar International Inc., an American group with global interests. It supplies South Africa's total demand for graphite electrodes and exports to several African countries.
The company’s manufacturing range includes speciality graphite products, graphite refractory furnace linings, graphite and carbon particles and powders. A graphite electrode is a device to conduct electricity down into an electric arc furnace which generates sufficient heat to melt scrap steel. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
