A direct smelting plant for producing molten metal from a metalliferous feed material using a molten bath based direct smelting process is disclosed. The plant includes a gas delivery duct assembly extending from a gas supply location away from the vessel to deliver oxygen-containing gas to gas injection lances extending into a direct smelting vessel. The gas delivery duct assembly includes a single gas delivery main connected to the gas injection lances to supply oxygen-containing gas to the gas injection lances. The gas delivery main is located at a height above a lower half of the vessel.

Direct smelting plant

A direct smelting plant for producing molten metal from a metalliferous feed material using a molten bath based direct smelting process is disclosed. The plant includes an offgas duct assembly to facilitate flow of offgas from the vessel, the offgas duct assembly including two offgas ducts of matching diameter extending outwardly from the vessel.

Solids injection lances for injecting solids into a metallurgical vessel are normally supplied with cooling water from a cooling water circuit through water supply lines and return lines. Supply lines are provided with spaced pairs of connectors and bypass valves, and return lines are provided with similar pairs of spaced connectors and bypass valves. Flexible hoses can be connected between the pairs of connectors to establish supply and return flows of cooling water which bypass segments of the main supply and return lines which can be isolated and removed to allow withdrawal and subsequent replacement of the lances.

Lance extraction

Metallurgical processing installation comprising a metallurgical vessel lined internally with water cooled panels. A vessel access tower () fits around vessel () and supports a coolant flow system () to provide for flow of cooling water to and from the cooling panels within the vessel through water inlet and outlet connections () distributed around the exterior of the vessel. Coolant flow system () includes large diameter water supply and return pipes () mounted on an upper part of the tower () to extend around the upper end of vessel (), a first series of vertical dropper pipes () of relatively small diameter connected to the main water supply pipeand extending downwardly to connections with the water inlet connectors for respecting cooling panels of the vessel and a second series of smaller diameter vertical pipes () connected at their upper ends to the main return pipe () and at their lower ends to undivided outlet connectors for the cooling panels in the vessel.
