PURMETALL Electric arc furnace
In an electric arc furnace scrap iron and/or pig iron are melted using electrical and chemical energy and are heated until tapping temperature has been reached. The success of a steelworks is highly dependent on the frequent availability of the electric arc furnace. To facilitate this you must choose the right refractory material.
