Family of synthetic slags developed in the form of sintered, pelletized or blends according to customer needs, with application in primary or secondary refining, steel pans and iron-alloys, with specific objectives, such as: absorption of inclusions; desulfurization of steel; sulfur stabilization.
We produce briquetted synthetic slag based on a mixture of powdered corundum and other raw materials with a high content of alumina, which is the main active ingredient of the product. Using a suitable combination of synthetic slag with lime and other slag-forming additives, we can produce basic refining slag with a low melting point. The slag is active and fluid, which is exactly what is needed to produce high-quality steel with low sulphur content and low content of undesirable inclusions.
