摘要： In a process for utiliting zinc-containing metallurgical dusts and sludges, the zinc-containing dusts and sludges are agglomerated, briquetted in a cold manner or pelletized and are added to the charge of a melting furnace for melting metal from metallized charges such as, scrap iron or pig iron. For this purpose, there are in particular used agglomerates or pellets having a metallizing degree of at least 30 percent by weight, preferably of at least 40 percent by weight.

摘要： In order to produce a microkilled steel suitable for free-run continuous casting for subsequent cold forming standardizing of the C - content to .ltoreq.0.05%, preferably .ltoreq.0.03%, Si - content to .ltoreq.0.05%, preferably 0.02-0.04%, and Al - content to .ltoreq.0.006% is proposed. For the equivalent carbon content a value .ltoreq.0.14%, preferably 0.10-0.12% is standardized using the correlationC.sub.eq =%C+1/7%Si+1/5%Mn+1/7%Cr+1/20%Ni+1/9%Cu+1/2% Mo+1/2% Vfor determining the equivalent carbon content. Preferably, the steel is refined in a bottom blowing or bottom rinsing converter and after standardizing the Si - content and/or Mn - content, oxygen activity a.sub.[o] is measured and standardized to 60-150 ppm by adding a corresponding amount of an additional deoxidant, particularly aluminum.

摘要： In a process for continuously melting scrap (6) and/or pig iron within a converter (1), the converter (1) is heated in proximity of the bottom (3) with sub-stoichiometric burners (4), having their flames (5) essentially radially directed into the interior of the converter (1). In this case, secondary air or O.sub.2 is supplied at a distance above the burner plane for the purpose of completing the combustion. The melt is, optionally together with slag, discharged via a tapping means (9) laterally connected to the converter (1) into a mobile ladle (19). For the purpose of interchanging ladles (19), the converter (1) is swivelled into a position in which the level of the melt is located below the taphole (11).

摘要： At least two magnetic induction elements operated with alternating current are disposed successively in the longitudinal direction at the guide for a strand of a continuous casting plant, and in particular for a continuous steel casting plant, to provide a stirring mechanism. Each induction element is connected to its own phase (R, S, T, N) of the at least two phase alternating current and the phases (R, S, T, N) are shifted with respect to each other by a phase angle of from about 0 to 180 degrees. In order to avoid the formation of a continously uniformly directed circulating current of metal despite a simple and sturdy stirring provision and without the presence of additional switching circuits, the phases (R,S,T) generate in each case electromagnetic forces under formation of a magnetic alternating field at at least two neighboring induction elements, where the momentary value differences and the directional differences correspond to a phase shift of .PHI.+180 degrees.

摘要： An apparatus for heating steel melts covered with a slag rich in iron oxide, and employed in particular for continuous steel making processes such as the KVA process, incorporates a height-adjustable injection lance for supplying metals which react exothermally with the melt and with the oxygen in the slag. The nozzle of the injection lance is adjustably arranged above the contents of the ladle so that it can be maintained in the zone of the melt/slag phase boundary.

摘要： A method of establishing a turbulent motion of molten steel within a strand guide of a continuous casting plant for casting a steel strand, wherein at least one group of three electromagnetic induction coils are arranged adjacent the strand guide, two of the induction elements being arranged consecutively in the longitudinal direction of the guide. At least two of the induction elements are offset relative to each other, transverse to the longitudinal direction of the strand guide, and the three induction elements form the corner points of an imaginary triangle having no more than one side lying in a plane extending parallel or perpendicular to the longitudinal direction of the strand guide. The imaginary triangle extends across the width of the strand. One phase of a three phase AC current is connected to each electromagnetic induction element. One of the induction elements has its input terminals electrically reversed with respect to the other two elements. When power is applied to the induction elements, a discontinuous electromagnetic AC field is established within the imaginary triangle extending across the width of the strand, wherein the electromotive forces produced by the induction elements produce travelling waves in several directions to cause a turbulent motion and an effective mingling of the melt within the strand over the total width of its liquid core.
