Abstract: A method of slag-free teeming of metal melt includes arranging outside of the metal vessel and closely adjacent to the discharge edge of the vessel discharge opening, of a jetting lance an inclination of which relative to a bath surface in the vessel and spacing from the discharge edge is changeable and injecting, through the discharge opening of the melt vessel, immediately before start of the teeming process and during the teeming process, a fluid jet having a high kinetic pulse energy substantially parallel to the bath surface for forcing a slag melt, which is located in a discharge region of the vessel and covers the metal melt, back.

Abstract: In a method of treating alloyed carbon-containing iron melts for the production of steel, whereby a carbon-containing iron melt is subjected in a metallurgical vessel to a decarburization by addition of oxygen and a part of the metallic alloying elements is slagged, whereby the metal melt is withdrawn from the metallurgical vessel while the unreduced slag remains in the metallurgical vessel and then the metallurgical vessel is filled with a new charge or iron melt and subjected anew to a decarburization process so that the loss of expensive metallic alloying elements as a result of decarburization is small because of the slagging. This is achieved in that without intervening removal of the slag, the slag is increasingly, saturated with metal oxides which derive from the melt and such that with increasing saturation the slagging of the metallic alloying elements is increasingly counteracted.

Abstract translation: 在用于生产钢的合金含碳铁熔体的处理方法中，通过添加氧将含碳铁熔体在冶金容器中进行脱碳，并且将一部分金属合金元素排渣， 将金属熔体从冶金容器中取出，而未还原的渣保留在冶金容器中，然后冶金容器中填充有新的电荷或铁熔体，并重新进行脱碳过程，从而导致昂贵的金属合金元素的损失 由于造渣，脱碳量很小。 这是通过没有间歇地去除炉渣来实现的，炉渣越来越多地被来自熔体的金属氧化物饱和，并且随着饱和度的增加，金属合金元素的结渣越来越多地被抵消。

Abstract: A method for recovering metallic chromium from slags which contain chromium oxide from converter processes, such as AOD, MRP, AOD-L, MRP-L, CLU, ASM, Conarc stainless steel or vacuum processes, such as VOD, SS-VOD, RH, RH with lanze, includes drawing off the slag which is produced at the end of a blowing or treatment operation in a converter or a vacuum installation in unreduced form. The slag is charged into an electric furnace, which is also charged with a standard charge of scrap and, if appropriate, dust residues. Carbon and, if appropriate, silicon are additionally added to the electric furnace.
