Problems solved by technology

[0022] In particular, applicants have recognized that space constraints make it difficult to use an overhead crane to transport a ladle containing molten metal to a location where the ladle can be tilted to pour molten metal directly into the molten metal inlet of the vessel

Embodiment Construction

[0081] The direct melting plant shown here is designed to produce solid ingots and includes:

[0082] (a) direct smelting vessels (SRV) for the production of molten iron from ferrous metal feedstocks such as iron ore by a molten bath based direct smelting process, such as the HIsmelt process,

[0083] (b) a desulfurization plant for desulphurization of molten iron discharged from the vessel (SRV), comprising a first desulphurization station 19 adjacent to the vessel (SRV) ( Figure 5 and 6 ) and the second desulfurization station 21 ( figure 2 and 5 ),

[0084] (c) a casting plant 23 comprising two casting machines 43 for casting desulfurized molten iron from the desulfurization plant into solid ingots,

[0085] (d) a plurality of steel ladles 7 ( figure 2 , 5 and 6), which is used to transfer the molten iron discharged from the vessel (SRV) through the desulfurization equipment to the casting equipment 23; and

[0086] (e) Hot metal supply equipment for producing molt...

Abstract

A hot metal supply apparatus for supplying molten metal from a remote furnace (5) to a direct smelting plant, for example for use in starting up a direct smelting process in the direct smelting vessel(SRV), is disclosed. The apparatus includes a transfer apparatus for transferring molten metal from a furnace (5) that produces the molten me to the direct smelting vessel (SRV), said transfer apparatus includes a hot metal receiving station for receiving molt metal from the furnace (5) and supplying the molten metal into the vessel (SRV), and the hot meatal receiving station includes a runner (37) that extends outwardly from the vessel (SRV).

Description

technical field [0001] The present invention relates to hot metal initiating a bath-based direct melting process for producing molten metal within a direct melting vessel. [0002] In particular, the invention relates to an apparatus for supplying hot metal, ie molten metal, to a direct melting vessel. [0003] In particular, but by no means exclusively, the present invention relates to a bath-based direct smelting process for the production of molten iron from ferrous metal feedstocks such as iron ore, partially reduced iron ore and ferrous Waste streams (eg from steelworks). Background technique [0004] The known bath-based direct smelting process is generally referred to as the HIsmelt (Direct Smelting Reduction Ironmaking) process. In the case of the production of molten iron, the HIsmelt process consists of the following steps: [0005] (a) forming a pool of molten iron and slag in the direct melting vessel; [0006] (b) The following materials are injected into th...
