The invention relates to a method for producing a metal melt in a metallurgical vessel, in particular an iron or steel melt, feed substances which contain metals and/or metal oxides, being charged in solid and, if appropriate, molten form into the metallurgical vessel, the main part of the energy necessary for the melting and, if appropriate, finish-reduction of the feed substances being applied electrically and/or by the combustion and/or gasification of carbon-containing materials. The invention relates, further, to multi-functional lances for use in a method according to the invention.

In a method for producing alloyed steels, wherein in a first manufacturing step iron carriers are to a great extent decarburized and dephosphorized by means of oxygen and after removal of the slag resulting therefrom the melt is adjusted to the desired alloy and carbon content in a further manufacturing step after addition of alloy carriers by means of oxygen and inert gas. Especially in order to produce stainless steels in an economical manner while achieving a high level of productivity, in particular while charging major amounts of solids,

In a method of cooling a hot surface, a liquid cooling medium is atomized by a plurality of nozzles in a hollow space surrounding the surface and open towards the atmosphere. In order to ensure uniform continuous, yet just sufficient, cooling of the hot surface, with the cooling effecting with a constant temperature as possible over an extended period of time while avoiding changing thermal expansions of the hot surface, the liquid cooling medium is continuously atomized by means of unary nozzles to a fine mist having a droplet size ranging between 4 and 60 .mu.m. The mist leaves the unary nozzles at a low speed and is moved along the hot surface within the hollow space surrounding the hot surface under utilization of the natural thermal current in the hollow space.

There is disclosed a process for producing an iron melt in a reactor with current supply. In order to utilize fine-grained iron carriers in a particularly economic manner while minimizing the energy input when carrying out such process in an electric arc furnace, it is proceeded in the following manner:
