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.
Abstract: A camera is arranged to map defects in the molten metal bath formed by scarfing using a scarfing torch on a steel slap. The camera has a field of a large area of the slab and records the defects as flashes of high intensity light the nature of which identifies the type of defect.
Abstract: A method of making a pneumatically injectable additive for an Electric Arc Furnace, the method comprising screening a waste material comprising oily millscale in water to form uniform particles, and then mixing those particles with carbon and lime; and storing the mixture in air permeable bags in a dry atmosphere until the mixture has chemically cured to form the injectable particles.
Abstract: The absolute position of a vehicle (V) transporting articles between sites (SS) at an installation, e.g. stations of a steel works, is determined by satellite navigation signal and logged on a CPU with a database to ensure that the intended articles (SR) are processed on different sites as required.
