Abstract

A combined ironmaking and steelmaking plant is disclosed.
The plant includes a direct smelting ironmaking plant that includes an ironmaking vessel and a steelmaking plant for producing molten steel from molten iron from the iron making plant. The steelmaking plant includes a steelmaking vessel such as a BOF. The plant also includes a plurality of ladles for molten iron and a transfer means for transferring the ladles between (i) an operative position at the ironmaking vessel for receiving molten iron from the ironmaking vessel and (ii) an operative position at the steelmaking vessel for discharging molten iron directly into the steelmaking vessel. The transfer means links together the ironmaking vessel and the steelmaking vessel.
The transfer means includes a transfer crane for supporting the ladles and a transfer crane runway that defines a path of movement for the crane.

Claims (21)

1. A combined ironmaking and steelmaking plant includes:
(a) a direct smelting ironmaking plant for producing molten iron from an iron-bearing metalliferous feed material such as ores, partly reduced ores and iron-containing waste streams, the ironmaking plant including an ironmaking vessel;

(b) a steelmaking plant for receiving molten iron and producing molten steel from molten iron, the steelmaking plant including a steelmaking vessel;
(c) at least one receptacle for receiving and holding molten iron from the ironmaking vessel and for discharging molten iron directly into the steelmaking vessel; and (d) a transfer means for transferring the receptacle between (i) an operative position at the ironmaking vessel at which the receptacle can receive molten iron from the ironmaking vessel and (ii) an operative position at the steelmaking vessel at which the receptacle can discharge molten iron directly into the steelmaking vessel and thereby links together the ironmaking vessel and the steelmaking vessel, the transfer means including a transfer crane for supporting the receptacle and a transfer crane runway that defines a path of movement for the crane.
2. The combined plant defined in claim 1 wherein the the ironmaking vessel is adapted to discharge molten iron continuously from the vessel.
3. The combined plant defined in claim 2 includes at least two receptacles and the ironmaking plant includes a means for selectively supplying molten iron discharged continuously from the ironmaking vessel into one or other of the receptacles at the operative position at the ironmaking plant.
4. The combined plant defined in any one of the preceding claims wherein then operative position at the steelmaking vessel is an elevated position in relation to the operative position at the ironmaking vessel.
5. The combined plant defined in any one of the preceding claims further includes a molten iron treatment plant for treating molten iron positioned in relation to the transfer crane runway so that a receptacle containing molten iron can be transferred from the operative position at the ironmaking vessel to an operative position at than molten iron treatment plant thereafter the molten iron can be treated at the molten iron treatment plant, and the receptacle can then be carried by the transfer crane along the transfer crane runway to the operative position at the steelmaking vessel and the treated molten icon can be discharged directly from the receptacle into the steelmaking vessel.
6. The combined plant defined in claim 5 wherein wherein the ironmaking vessel and the molten iron treatment plant are on opposite sides of the transfer runway.
7. The combined plant defined in claim 6 wherein the operative positions at the ironmaking vessel and the molten iron treatment plant are directly across from one another.
8. The combined plant defined in any one of claims 5 to 7 wherein the transfer means includes a transfer car or other suitable molten iron transfer means for supporting and transferring the receptacle containing molten iron from the operative position at the ironmaking vessel to the operative position at the molten iron treatment plant.
9. The combined plant defined in claim 8 wherein the transfer means includes a rail-mounted transfer car for supporting and transferring the receptacle means containing molten iron from the operative position at the ironmaking vessel to the operative positions at the molten iron treatment plant.
10. The combined plant defined in claim 9 wherein the transfer car and the transfer crane are adapted to operate independently of each other
11. The combined plant defined in any one of claims to 10 wherein the molten iron treatment plant is a desulphurisation plant that is adapted to desulphurise molten iron in the receptacle in situ on the molten iron transfer means.
12. The combined plant defined in any one of the preceding claims further includes a molten iron solidification plant for casting molten irons into pigs or other moulds or for quenching molten iron into granules or for otherwise forming solid iron positioned in relation to the transfer crane runway so that a receptacle containing molten iron can be carried by the transfer crane along the transfer crane runway to an operative position at the solidification plant and molten iron can be discharged from the receptacle into the solidification plant.
13. The combined plant defined in claim 12 wherein the operative position at the steelmaking vessel and the operative position at the solidification plant are at opposite ends of the transfer crane runway.
14. The combined plant defined in any one of the preceding claims further includes a receptacle heating stand positioned is relation to the transfer crane runway so that as empty receptacle can be heated at the the receptacle heating stand and thereafter carried by the transfer arena along the transfer crane runway to the operative position at the ironmaking vessel to be filled with molten iron.
15. The combined plant defined in any one of the preceding claims wherein the direct smelting ironmaking plant is adapted to produce molten iron by a molten bath-based direct smelting process.
16.~The combined plant defined in any one of the preceding claims wherein the receptacle is a ladle.
17. The combined plant defined in claim 16 wherein the transfer crane and the ladle are adapted to allow for tilting a ladle containing molten iron towards the steelmaking vessel so that molten iron can be discharged from the ladle while supported by the transfer crane.
18. The combined plant defined in claim 16 or claim 17 wherein the steelmaking vessel is adapted to tilt towards a ladle containing molten iron when the ladle is at the operative position of the steelmaking vessel to facilitate discharging of molten iron into the steelmaking vessel.
19. A method of making steel in the combined ironmaking and steelmaking plant defined in any one of the preceding claims, includes: making molten iron in the direct smelting ironmaking plant, discharging molten iron from the ironmaking vessel into the receptacle at the operative position of the ironmaking plant, transferring the receptacle containing the molten iron to the steelmaking plant using the transfer means, discharging
20 molten iron from the receptacle into the steelmaking vessel, and making steel from the molten iron in the steelmaking plant.

20. The method defined in claim 19 further includes transferring the receptacle containing the molten iron from the ironmaking plant to the molten iron treatment plant using the transfer means, treating the molten iron at the molten iron treatment plant, and thereafter transferring the receptacle containing the treated molten iron to the steelmaking plant.
21. The method defined in claim 19 or claim 20 includes continuously discharging molten iron from the ironmaking vessel into one of two receptacles at operative positions of the ironmaking plant.
