Electric smelters and submerged arc furnaces


As a result of changing economies and the manner in which commodities are processed due environmental contains, SMS group predicts a growing demand for new and/or revamped electric smelting units. Electric smelters and Submerged Arc Furnaces (SAFs) are common furnaces for the production of ferro-alloys and other metals, where larger amounts of slags are processed and treated. SMS group relies on an impressive reference base of over 1,000 electric furnaces supplied to customers in the iron, steel, ferro-alloy, chemical, TiO2, and non-ferrous metals industries.

Submerged Arc Furnaces

Submerged Arc Furnaces are ideal for smelting ore concentrate, calcine, pre-reduced ores as well as waste materials such as deposits, flue dust, slags, refractory breakout waste, and skulls. The units are highly diversified and specially developed depending on the input materials and product requirements.
