| An iron production furnace equipment (1) has a melting reactor (2) into which iron oxide-containing raw material (4) and slag formers (5) are added. A melter arrangement (22) melts the iron oxide-containing raw material and transforms the melted raw material into liquid slag (6) A smelting reduction reactor (3) is connected to the melting reactor by a slag transfer arrangement (10). The smelting reduction reactor comprises a heater arrangement (30) for heating the slag. Means (32) for supplying a reductant (7) for reducing the iron oxide in the slag into a liquid iron melt (8) and for producing a combustible gas mixture (11) comprising at least one of CO and H 2. A gas connection (12) is connected between the smelting reduction reactor and the melter arrangement. The melter arrangement in turn comprises a combuster (28) combusting the gas mixture.

| A filter for molten metal is an open-pored porous material comprising particles of refractory material embedded in and bonded together by a carbon matrix bonding material. The filter can be made by forming a porous article from refractory particles, e.g. refractory oxide, carbide or graphite, and a carbon-rich binder, e.g. tar, pitch or an organic (preferably aromatic) polymer that degrades to form carbon on pyrolysis, and then firing the porous article to generate the carbon matrix in which the refractory particles are embedded. The porous article is preferably made by coating a reticulated polyurethane foam with binder and refractory particles, and firing at preferably no higher than 800 DEG C. | ||||||

There are provided a gas blowing plug with a long life and a manufacturing method therefor. The gas blowing plug for blowing gas from the bottom of a molten metal vessel comprises a slit-shaped gas passage ranging from the bottom to the top of the plug. The gas passage is formed by a continuous or discontinuous slit-shaped gas passage in the horizontal cross section of the plug, and is formed by a slit-shaped gas passage continuous from the bottom to the top of the plug and a discontinuous slit-shaped gas passage in the vertical cross section of the plug. The cross-sectional shape of a tubular body can be a star shape, for example. |

| Dispositif pour la fabrication de l'acier avec agitation inductive du bain d'acier dans un récipient contenant celui-ci. Il est souhaitable que les diverses zones de l'acier en fusion soient poussées vers la surface du bain, tout en étant mélangées afin d'être exposées à une surface aussi grande que possible. Ce problème a été résolu par l'agitation inductive, grâce à l'établissement d'au moins un champ magnétique qui agit sur la partie inférieure du bain d'acier et qui oblige l'acier à tourner dans un plan horizontal et dans un sens déterminé, ainsi que par l'agitation inductive obtenue par l'établissement d'au moins un champ magnétique supplémentaire qui agit sur la partie supérieure de l'acier l'entraînant essentiellement dans le sens opposé. | ||||||
| 116 | Method of reducing lining wear in a ladle containing a melt | EP88105362.3 | 1988-04-02 | EP0286934A1 | 1988-10-19 | Ekander, Hans; Ericson, Clas; Tallbäck Göte; Tinoco, Hernan; Öström, Staffan |
A method to reduce lining wear in a ladle containing a steel melt, which is heated by at least one electric arc and rotated by an electromagnetic stirrer in a horizontal direction such that a parabolic surface forms on the melt and the slag present in the melt is forced to accumulate towards the centre, thus protecting the ladle lining against the attack of slag and partially against arc radiation. The arc, in addition to heating the charge, also melts the slag. A disturbing device, such as a ceramic pole, a ceramic stone, for example a brick projecting into the melt, a ceramic wing immersing into or arranged below the bath surface, or an electromagnetic brake (18), is arranged such, preferably by immersion into the interface between melt and slag, as to bring about an efficient mixing of steel melt and slag. |

| Afin de permettre l'injection de substances dans un liquide, par exemple du métal en fusion, un bloc d'ajutage (21) est monté dans la paroi d'un récipient (13) contenant le liquide. Un passage d'injection (11) s'étendant à travers le bloc est fermé au début par un bouchon (22) empêchant l'entrée du liquide, ce bouchon (22) étant poussé latéralement, juste avant le commencement de l'injection, par une conduite de distribution (24) mobile dans le passage (11), la conduite (24) faisant partie d'un assemblage de lance d'injection. Les positions de l'assemblage de lance avant et après l'injection sont déterminées par un agencement d'arrêt de sécurité, comprenant par exemple une détente sous la forme d'un piston à ressort (60) logé dans une partie fixe (32) du dispositif; le piston agit de concert avec des plans inclinés avant et arrière (65, 66) d'un appui (64) solidaire de la partie (25) de l'assemblage de lance, pour déterminer les positions de l'assemblage de lance avant et après l'injection. | ||||||
