Our international experts are passionate about electric smelters and submerged-arc furnaces for TiO2 slag, CaC2, minerals, refractories, ferroalloys, silicon, and non-ferrous metals. This is a field where SMS group in Düsseldorf and Metix in Johannesburg pool their know-how for your benefit. Our team in Düsseldorf handles all SAF-related projects for electric smelters and submerged-arc furnaces worldwide, except in Southern Africa. That leaves Metix responsible for all submerged-arc furnace and electric smelter projects in the southern African region.
What's more, Metix supplies feed material pre-heating systems as well as pellet and sinter plants. Paul Wurth provides support with refractory design and tapping/stoking equipment. We join forces with you to work together in partnership, always finding the best possible solution. Our teams are available at any time to stand by your side and help you get the results you want.
Application
Know-how is necessary
What makes electric smelters for special applications particularly challenging is that they are usually tailor-made to meet unique requirements. This means special know-how is necessary for their technological development. That's why, we have, in recent years, engineered and supplied the core equipment for units producing CaC2 slag, TiO2 slag, and hot metal, as well as fused magnesia and dephosphorization furnaces. We also supply test and pilot furnaces for upscaling new processes. All our units are custom-made.




Titanium slag
You can derive an extra benefit from titanium slag furnaces because they produce TiO2-rich slag and pig iron as valuable by-products. The ilmenite ore can be processed in either DC or AC furnaces ...




Calcium carbide (CaC2)
Calcium carbide (CaC2) is the raw material for acetylene and calcium cyanimide. Today it's mainly used in the chemical industry and as a desulfurization agent in steel production. ...




General minerals
Our furnaces are also used in various fields for refractory and mineral production.
That's because SAFs are ideal for producing these products: ...
Ferro silicon and silicon
Technically, the furnaces used for silicon and Ferro silicon (FeSi) are very similar. Yet the materials have different applications. Most FeSi goes to the steel industry, whereas silicon is used much more widely: in steel and aluminium production, the chemicals industry for producing silicones, and in electronics, etc. Typically, ferro-silicon grades produced in submerged-arc furnaces have SI contents from 15 to 96%. Grades with more than 96% Si are known as silicon. The high energy concentration and process gas formation involved here place extreme demands on the design and material of these furnaces.




Approaches & Technology
Experience for the future
Crucial for our excellent design are our experienced experts, plus a strong R+D department, and advanced engineering tools. All this makes it possible to calculate complex structural furnace parts and intensive thermal areas. These are capabilities even more important for designing large-capacity furnaces. Moreover, FEM calculation is an extra option for cutting electrical losses with alternating magnetic fields.
Our customers have told us again and again that our designs result in reliable and efficient plants. That's because our engineering also ensures long equipment and component service lives. Some SMS group furnaces have been in operation for more than 40 years - and are still running smoothly.
During recent decades, we have developed numerous smelter solutions to cope with the specific conditions dictated by various processes. Take a look at the resulting wide range below.
