Problems solved by technology

Set up railway station systems, signaling systems, dispatching systems, maintenance and inspection systems, set up iron casting machine systems along the railway line, iron ladle repair and baking systems, locomotive maintenance systems, etc. The system is complex, which brings long distances between ironmaking and steelmaking processes , the transportation cycle is long, the temperature drop of molten iron is large, the scope of smoke and dust pollution is large, the railway system occupies a large area, has a large number of personnel, and has many accident points, etc., which gradually deviates from the goal of modern steel plants to achieve good economic and environmental benefits.
[0006] (2) Use straddle-car rail transportation and foundry crane transportation to replace traditional railway transportation. The ironmaking and steelmaking processes are relatively close and the layout is regular. However, iron ladle transfer spans, transition spans, buffer spans, etc. are set between iron and steel processes. Large-tonnage foundry cranes are required for multi-stage operations, which will result in large plant loads, high headroom, and large investment
Due to the limitations of the power source of the straddle car rail transportation, it is often necessary to have a cable reel or use a trolley line to supply power, which is only suitable for straight-line transportation, and the flexibility of transportation and layout is poor.

Embodiment 1

[0032] A molten iron transportation system at the ironmaking-steelmaking interface

[0033] Such as figure 1 As shown: it is a specific embodiment of the present invention, after the molten iron transportation unit 3 receives iron under the ironmaking workshop 1, it is transported to the turntable 4 through the first molten iron transportation track 2, and after being turned by the turntable 4, it is turned along the second molten iron The transport track 5 is transported to the steelmaking workshop 6 or the iron casting machine 7, and the molten iron transport unit 3 returns to the ironmaking workshop 1 from the steelmaking workshop 6 and runs in reverse along the above path. Another kind of arrangement of this embodiment is two ironmaking workshops 1 to a steelmaking workshop 6, as figure 2 shown.

Embodiment 2

[0035]A molten iron transportation system at the ironmaking-steelmaking interface

[0036] Such as image 3 As shown, the others are the same as in Embodiment 1, the difference is that: the turntable 4 is turned and transported along the second molten iron transport track 5, and the molten iron transport unit 3 on the second molten iron transport track 5 at the far end of the blast furnace can be pulled by the steelmaking front. The car platform 8 enters the steelmaking workshop 6 after changing the line, and the curve and the turnout arrangement on the second molten iron transport track 5 are cancelled. Another kind of arrangement of this embodiment is two ironmaking workshops 1 to a steelmaking workshop 6, as Figure 4 shown.

Embodiment 3

[0038] A molten iron transportation system at the ironmaking-steelmaking interface

[0039] Such as Figure 5 As shown, the others are the same as in Embodiment 2, the difference is that: the first molten iron transportation track 2 is transported to the leading vehicle platform 9 in front of the blast furnace, transported to the turntable 4, and the turntable 4 is turned to be transported along the second molten iron transportation track 5 to The puller platform 8 before steelmaking enters the steelmaking workshop 6, and the curve and the turnout arrangement on the molten iron transportation track 2 under the furnace are cancelled. Another kind of arrangement of this embodiment is two ironmaking workshops 1 to a steelmaking workshop 6, as Figure 6 shown.

Abstract

The invention discloses a molten iron transportation system for an ironmaking-steelmaking interface, and belongs to the technical field of metallurgical ironmaking-steelmaking interfaces. The molten iron transportation system comprises an ironmaking workshop, a molten iron transportation track, a molten iron transportation unit, a turntable, a traction platform, a steelmaking workshop and an ironcasting machine; the molten iron transportation track comprises a first molten iron transportation track body, a second molten iron transportation track body and a third molten iron transportation track body; the traction platform comprises a steelmaking front traction platform, a blast furnace front traction platform, an empty car traction platform, a blast furnace rear traction platform and a steelmaking workshop interior traction platform; and one or more blast furnace ironmaking workshops and one converter steelmaking workshop are arranged in a combined mode. The molten iron transportationsystem has the advantages that through compactness and regularity of overall drawing arrangement, the environmental benefits of reducing the molten iron temperature drop, reducing the iron loss, reducing energy consumption, reducing engineering land occupation, reducing the smoke dust emission range and reducing smoke dust pollution are brought, and meanwhile, the economic benefits of reducing the equipment input, reducing casting cranes and plant construction and reducing engineering investment are brought.

Description

technical field [0001] The invention belongs to the technical field of ironmaking-steelmaking transportation, in particular to a molten iron transportation system at the ironmaking-steelmaking interface. Background technique [0002] In the past ten years, with the rapid development of metallurgical technology, the interface technology has attracted more and more attention from the metallurgical industry. The "one tank to the bottom" molten iron transportation process between the ironmaking and steelmaking interface has gradually replaced the traditional torpedo tanker for the canning operation. With the increasingly mature production process of "one pot to the bottom" between the ironmaking and steelmaking process interface, its superiority is more and more obvious in the production of steel plants. Its technology will undertake, transport and buffer blast furnace molten iron The functions of storage, molten iron pretreatment, converter iron mixing, container rapid turnover...
