Abstract:
A vertical reduction furnace for the production of metallic iron by means of the direct reduction of iron ore (DRI), comprising an iron ore feed zone, an iron ore reduction zone, a metallic iron discharge zone (3), accumulation means (6) communicating at an inlet end with the metallic iron discharge zone (3) and at an outlet end with gas sealing means (7). The accumulation means may accumulate the metallic iron along with the off-gases from the reduction process.
Abstract:
A mud that provides a work environment improvement as the characteristics of a resinous mud for the tap hole of a blast furnace, improves the adhesiveness with a mud piled in the furnace at high temperature as a shortcoming and can increase the depth of the tap hole. This mud is characterized in that 8-20 wt% of a solution of novolack phenol resin having a specified number average molecular weight is blended with the conventional heat-resistant aggregate for the mud as a binder for caking.

Abstract:
An apparatus for injecting solid material into a vessel, such as a direct smelting vessel. The apparatus has a central tube comprising: a core tube assembly that defines a passageway for solid material, the core tube assembly having at least one core tube and having an inlet for receiving solid material at a rear end and an outlet at a forward end; an outer sheath that extends over at least a portion of the core tube assembly, the outer sheath having an internal diameter that is greater than the outer diameter of the core tube assembly such that a substantially annular clearance is provided between the core tube assembly and the outer sheath; and a cementing agent that fills the annular clearance and forms a bond that secures the core tube assembly within the outer sheath.
Abstract:
Bei einem Verfahren zum Reduzieren von metalloxidischen Schlacken bzw. Gläsern und/oder Entgasen von mineralischen Schmelzen werden feste Partikel und/oder Schmelzen auf ein zumindest teilweise induktiv erhitztes Bett oder eine Säule mit stückigem Koks aufgegeben und die ablaufende reduzierte und/oder entgaste Schmelze wird gesammelt. Die Vorrichtung zum Reduzieren von metalloxidischen Schlacken bzw. Gläsern und/oder Entgasen von mineralischen Schmelzen mit einer Aufgabeöffnung (1) für festes oder schmelzflüssiges Material und einer Abstichöffnung (12) für die behandelte Schmelze ist gekennzeichnet durch ein röhr- oder rinnenförmiges Gehäuse (3) für die Aufnahme von stückigem Koks (6), und eine das Gehäuse (3) umgebende, wenigstens eine Induktionsspule (7, 8, 9) enthaltende Heizeinrichtung.
Abstract:
Method of constructing and installing a direct smelting unit comprising a smelting vessel (11). The vessel is prefabricated off site in three modules (11A, 11B, 11C) which are then transported to the installation site where they are hoisted by a crane and deposited sequentially on top of one another and joined together by welding to form a unitary vessel. The vessel modules are prefabricated so as to be internally lined with water cooling panels connected to water inlet and outlet connectors (62) on the exterior of the circumferential wall sections of those modules. A vessel access tower is formed in modules brought together to envelop the tower and carrying water supply and return piping which is connected to the water inlet and outlet connectors (62) of the cooling panels.
Abstract:
A method and apparatus for simultaneously supplying varying proportions of hot and cold direct reduced iron (DRI) material from a source of hot DRI for melting, storage, briquetting or transport. The system uses gravity to transport hot DRI material from a reduction furnace (10) to a furnace discharge section (12), which transports desired amounts to a cooling receptacle (20), and to a hot DRI vessel (30). The cooling section (20) of the apparatus is connected to the furnace discharge section (12) through a dynamic seal leg (14). The hot section (30) is also connected to the furnace discharge section (12) through a separate dynamic seal leg (14) and can feed a surge vessel (6), a briquetter (72), a storage vessel (60) or a melting furnace (70). The method of operation is also disclosed.
