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： For the purpose of pouring a stepwise advanced casting mould consisting of identical, flaskless mould parts having vertical joints at which there are provided inlets or chutes extending from the top surface of the mould to its casting cavities, use is made of a pouring tundish having a slitlike bottom outlet adapted to cover three or more inlets temporarily blocked by an obstruction. After an additive has been fed to the tundish this is being filled with the necessary amount of molten iron which prior to removal of the obstruction gets the opportunity of being merged uniformly with the additive, and possible slag products may at the same time rise to the surface. The pouring tundish may meanwhile be advanced one or more steps together with the casting mould while being in firm contact with its top face. After the pouring step has finished the pouring tundish may be disengaged from the casting mould and be returned past the starting position to be fed with additive, and is subsequently ready for a new operation. For a given cycle time of the plant, the period available for the pouring operation may be considerably extended, thereby entailing quality improvements in the produced castings.
摘要翻译：为了浇注由具有垂直接头的相同的无棚模具部件组成的逐步高级铸造模具，其中设置有从模具顶表面延伸到其铸造腔的入口或斜槽，使用具有狭缝状底部出口适于覆盖由阻塞暂时阻塞的三个或更多个入口。将添加剂加入到中间包之后，将其填充必要量的铁水，在除去阻塞物之前，有机会与添加剂均匀地合并，并且可能的渣产物可能同时上升到表面。倾倒式中间包可能同时与铸模一起提高一个或多个步骤，同时与其顶面牢固接触。在浇注步骤完成之后，浇注中间包可以从铸模脱离并返回到起始位置以供给添加剂，随后准备好进行新的操作。对于工厂的给定循环时间，浇注作业可用的时间可以大大延长，从而导致生产的铸件的质量改进。

摘要： Molten metal, such as aluminum, is held within rigid refractory lining means beneath, above and alongside the metal while heaters keep the outside of the lining means at a predetermined temperature desired for the metal, the heaters being surrounded by thermal insulation and the whole being surrounded by a fluid-cooled support. An unusually effective embodiment is pipe, with a tubular refractory liner to carry flowing metal, surrounded by sheathed heating elements controlled to keep the exterior of the tube at least at about the predetermined temperature, with the thermal insulation wrapped around the heaters and the enclosing support being a water-jacketed steel pipe. The operation is essentially adiabatic with respect to the refractory liner, delivering the molten metal essentially at its original temperature, with unusual saving of heat energy. When the heated pipeline has been drained, only easily removed, paper-thin skulls of solid metal remain.

摘要： An apparatus for use during continuous casting for the introduction of a metallic, typically steel melt into the casting head of a continuous casting mold, comprising a substantially tubular-shaped portion which directly merges with a pouring or casting vessel, the cross-sectional area of the tubular-shaped portion being greater than the cross-sectional area of the pouring outlet at the casting vessel. A chamber-like portion of larger cross-sectional area merges with the tubular-shaped portion. The chamber-like portion is equipped with a multiplicity of neighboring openings, the individual cross-sectional area of which is considerably smaller than the cross-sectional area of the tubular-shaped portion.

摘要： A method of, and apparatus for, the introduction of steel into the liquid metal pool of a continuous casting mold of a continuous casting installation, wherein a casting jet which is enclosed at its periphery at all sides is guided beneath the level of the molten bath of the liquid metal pool in the continuous casting mold and thereafter deflected out of its original position. The casting jet is guided substantially immediately after its aforesaid deflection substantially only at its underside to impart thereto an upwardly directed flow component, and the upper surface of the casting jet is permitted to freely admix with the steel of the liquid metal pool. The apparatus for the practise of the method comprises a pouring tube for the throughflow of a casting jet and a distributor device cooperating with the pouring tube. The distributor device comprises a distributor plate secured, preferably detachably, at the pouring tube, and the distributor plate has one or more guide surfaces for the casting jet emanating from the pouring tube, which guide surface or surfaces substantially only contact the outflowing casting jet at its underside to impart thereto an upwardly directed flow component in the mold.

摘要： The invention relates to a process for separating non-metallic inclusions from hot liquid metal and to a casting tube for carrying out such process. The method is employed in continuous casting, in which the metal is permitted to flow into a watercooled mould, if desired via a tundish, whereupon the bar is drawn out of the mould and further cooled. In this process the metal, when flowing through the tundish and/or when entering the mould, is deflected under formation of at least one metal stream directed in upward direction. The length a of this metal stream amounts to from 3 to 30 cm and its speed v is adjusted to increase proportionally thereto in a range of at least 3.5 to 31 cm/sec up to maximally 17.5 to 45 cm/sec so that at the surface of the metal or of the slag or casting powder layer a wave is formed. When a and v are maintained within the mentioned range, a sufficient separation is guaranteed and the formation of turbulences tending to rupture the slag layer is avoided.
