Abstract
This invention relates to a process for the recovery of slags originating from steelmaking operations and their conversion into a product obtained by that process. Hitherto these materials have been dumped. In fact so far no feasible process has been found for the conversion of the slags or for their direct use. The purpose of this invention is to find a method which is suitable for converting these slags into a product which is harmless to the environment and designed in such a way as to obtain a marketable product. Subdivided into the following stages: reduction of the slags to powder, mixing with iron oxides, the addition of an inert material to this mixture, addition of cement to this mixture, formation of a paste with water and a superfluidiser additive, forming of a product with a paste obtained.
