Abstract: A process and material for producing foamed slag by which the foaming of a slag with a high chromium oxide content can be achieved. An electric arc furnace is charged with a mixture of metal oxides and carbon and, below the slag at the metal-slag interface, the metal oxide is reduced by carbon and limestone and becomes thermally discordant. The occurring gases cause the slag to foam due to the formation of bubbles.

Abstract: A method of improving the post-combustion heat recovery in a basic oxygen furnace by controllably forming a foamy slag. The foamy slag is generated by increasing the lance height and reducing the rate of lance height reduction during the oxygen blowing cycle. The foamy slag is controlled to prevent slopping by calculating the approximate starting point of the peak decarburization period for the charge and then adjusting the oxygen flow rate to be at a minimum at the commencement of the peak decarburization period.

Abstract: A furnace 10 for smelting iron ore and/or refining molten iron 20 is equipped with an overhead pneumatic lance 40, through which a center stream of particulate coal 53 is ejected at high velocity into a slag layer 30. An annular stream of nitrogen or argon 51 enshrouds the coal stream. Oxygen 52 is simultaneously ejected in an annular stream encircling the inert gas stream 51. The interposition of the inert gas stream between the coal and oxygen streams prevents the volatile matter in the coal from combusting before it reaches the slag layer. Heat of combustion is thus more efficiently delivered to the slag, where it is needed to sustain the desired reactions occurring there. A second stream of lower velocity oxygen can be delivered through an outermost annulus 84 to react with carbon monoxide gas rising from slag layer 30, thereby adding still more heat to the furnace.

Abstract: During the production of non-stainless steel, slag containing a high proportion of metal oxides, primarily iron oxide, is formed during the smelting of the solid material in the electric arc furnace. The concentration of the iron oxide often reaches values of more than 20%. This slag has a poor foaming capability and does not permit the typical characteristics of a carbon steel slag to be achieved. In order to cause such a slag to foam, according to the invention it is proposed to load the electric arc furnace with pellets or briquettes (8) which consist of a defined mixture of an iron oxide carrier and an iron carrier as ballast material, of carbon as reducing agent and also of a binder material, which react in the electric arc furnace in a reducing manner, floating under the slag (7) in the steel melt (6). The reaction gases (12) produced in this way consist primarily of carbon monoxide and advantageously support the foaming of the slag.
