    Abstract: The additives, in particulate solid form, are conveyed pneumatically in a divergent stream from a pneumatic gun to impinge upon the molten iron and mix therewith. The gun is spaced above a surface of molten iron such that the pneumatically conveyed stream including the additive has a central axis which is either horizontal (or at an acute angle to the horizontal). The gun is preferably adjustable for adjustment of the stream angle, and the stream may be either added to pouring metal or to cover a surface of the molten iron.

    Abstract: The invention relates to a method of producing ferrochromium by the granulation of a melt comprising the steps of providing a ferrochromium melt comprising (wt. %): C: 1 – 9; 5 Cr: 25 – 70 and Si: ≤ 2.0. The method includes the steps of feeding the melt to a distribution unit, subjecting the melt to granulation by disintegrating the melt above and/or within cooling water held in a cooling tank, solidifying the disintegrated melt within the cooling water, thereby obtaining a granulated ferrochromium material with a mean size in the range of 12-50 mm wherein the amount of fines having a size of less 10 than 4 mm is limited to 7 %.

    Abstract: This invention relates to a method for dephosphorising liquid hot metal, such as liquid blast furnace iron or liquid metal with a composition equivalent to blast furnace iron, wherein a pouring stream of the hot metal is discharged from a vessel containing the hot metal into a refining unit wherein in the refining unit one or more streams of additives for forming a molten slag and one or more gaseous streams for breaking up the pouring stream of hot metal into molten metal droplets are directed into the pouring stream wherein one or more of the gaseous streams and/or one or more of the streams of additives comprises oxygen in gaseous form or in compounded form, to allow a dephosphorisation reaction between the metal droplets, the oxygen and the molten slag during the fall of the molten droplets before being collected into a receiving vessel positioned below the refining unit, and to an apparatus for performing the method.

    Abstract: A method, an installation and a nozzle (1) for suppressing the generation of iron-containing vapor during filling or emptying of a container (2) for an iron-containing metal melt with the aid of CO 2 snow, a CO 2 snow jet (22) being applied by means of the nozzle (1) dispersing in a substantially planar manner onto a surface of an iron-containing stream (23) which is poured into or out of the container (2). The invention consequently at least partially solves the technical problems outlined in connection with the prior art. In particular, a device is proposed which allows cost-effective and space-saving suppression of the generation of iron-containing vapor during the filling or emptying of a container 2 with the aid of a reduced CO 2 snow quantity.
