    Abstract: A direct smelting process for producing metal from a metalliferous feed material is disclosed. The direct smelting process is a molten bath-based process in which smelting occurs predominantly in the metal layer, carrier gas/metalliferous feed material/solid carbonaceous material are injected into the metal layer via lances/tuyeres, and oxygen-containing gas is injected into the top space above the molten bath and post-combusts reaction gases released from the bath. The injection of metalliferous feed material and solid carbonaceous material causes molten material to be projected from the molten bath as splashes, droplets and streams and to form a transition zone. The process is characterised by forming a pipe of a solid material on an outlet end of at least one lance/tuyere while injecting the metalliferous feed material and the carbonaceous material through the lances/tuyeres and thereby extending the effective length of the lance/tuyere or the lances/tuyeres.

    Abstract translation: 公开了由含金属原料生产金属的直接熔炼工艺。 直接熔炼过程是基于熔融浴的过程,其中熔炼主要发生在金属层中,载气/含金属原料/固体含碳材料通过喷枪/风口注入到金属层中,并且将含氧气体注入 熔池上方的顶部空间并且后燃烧从池中释放的反应气体。 含金属原料和固体碳质材料的注入导致熔融材料以飞溅,液滴和物流的形式从熔池中投射并形成过渡区。 该方法的特征在于,在至少一个喷枪/风口的出口端形成固体材料管,同时通过喷枪/风口喷射含金属原料和含碳材料,从而延长喷管/风口的有效长度或 枪/风嘴。

    Abstract: Zpusob prímého tavení pro výrobu kovu ze vsázkového materiálu obsahujícího kov je zpusobem založeným na roztavené lázni, pri kterém dochází k tavení prevážne ve vrstve kovu, pricemž jsou nosný plyn, vsázkový materiál obsahující kov, a pevný uhlíkatý materiál vhánené do vrstvy kovu prívodními trubkami/dmyšnami, a pricemž je plyn obsahující kyslík vhánen do horního prostoru nad roztavenou lázní pro prídavné spalování reakcních plynu, uvolnovaných z roztavené lázne. Vhánení vsázkového materiálu, obsahujícího kov, a pevného uhlíkatého materiálu zpusobuje vypuzování roztaveného materiálu z roztavené lázne ve forme rozstrikovaných a šplíchajících kapicek a proudu, pricemž vytvárí prechodovou oblast. Podstatou zpusobu je vytvárení trubky z pevného materiálu na výstupním konci alespon jedné prívodní trubky/dmyšny pri vhánení vsázkového materiálu obsahujícího kov, a uhlíkatého materiálu prívodními trubkami/dmyšnami, jehož úcelem je prodloužení úcinné délky prívodní trubky/dmyšny nebo prívodních trubek/dmyšen.

    Abstract: A DIRECT SMELTING PROCESS FOR PRODUCING METAL FROM A METALLIFEROUS FEED MATERIAL IS DISCLOSED. THE DIRECT SMELTING PROCESS IS A MOLTEN BATH-BASED PROCESS IN WHICH SMELTING OCCURS PREDOMINANTLY IN THE METAL LAYER (15),CARRIER GAS/METALLIFEROUS FEED MATERIAL/SOLID CARBONACEOUS MATERIAL ARE INJECTED INTO THE METAL LAYER (15) VIA LANCES/TUYERES (11),AND OXYGEN-CONTAINING GAS IS INJECTED INTO THE TOP SPACE ABOVE THE MOLTEN BATH AND POST-COMBUSTS REACTION GASES RELEASED FROM THE BATH. THE INJECTION OF METALLIFEROUS FEED MATERIAL AND SOLID CARBONACEOUS MATERIAL CAUSES MOLTEN MATERIAL TO BE PROJECTED FROM THE MOLTEN BATH AS SPLASHES,DROPLETS AND STREAMS AND TO FORM A TRANSITION ZONE (23).THE PROCESS IS CHARACTERISED BY FORMING A PIEP OF A SOLID MATERIAL ON AN OUTLET END (35) OF AT LEAST ONE LANCE/TUYERE (11) WHILE INJECTING THE METALLIFEROUS FEED MATERIAL AND THE CARBONACEOUS MATERIAL THROUGH THE LANCES/TUYERES (11) AND THEREBY EXTENDING THE EFFECTIVE LENGTH OF THE LANCE/TUYERE OR THE LANCES/TUYERES.FIG.1
