Abstract
A method for treatment of metallurgical wastes i.e. slags, which are in liquid form by introducing water into the liquid slag thus causing it to cool at a slow rate so that the solidified slag contains a porous crystalline or utrified structure according to the rate of cooling, which structure is stable at ambient temperature. Another object of the invention concerns an apparatus for treating solid metallurgical slags, comprising a continuous conveyor formed of molds and means adapted to diffuse water into the liquid slag.
Claims6
A method for treating steel slags coming out from steelworks furnaces of the LD type, converter, electric are or similar, being poured continuously onto continuous/endless conveyor formed of moulds and moved in order to gradually cool the liquid slag which is solidifying, wherein said method comprises introducing a lance to penetrate the liquid steel slag and thereby introducing and diffusing water into the liquid slag without causing an explosion thereof.
