Embodiment 1

[0023] In this embodiment, four tapholes are arranged under the casthouse 1 of the blast furnace, and two iron receiving lines 2 under each furnace are arranged under each iron outlet, and the iron receiving lines 2 under each furnace are obliquely arranged on the molten iron transport trunk line 4- side. Two molten iron transportation main lines 4 are arranged side by side, and the two molten iron transportation main lines 4 are respectively merged into a pull-out line 8 through a can pouring line 5, and empty can walking lines 7 are correspondingly provided at the side of the two can pouring lines. Empty can parking lines 9 are arranged side by side with the molten iron transportation trunk line 4 along the line direction of the molten iron transportation trunk line 4. There are multiple empty can parking lines, and each empty can parking line 9 is arranged at intervals along the molten iron transportation trunk line. Of course, the number of tapholes under the blast furnace...

Embodiment 2

[0028] As another layout form of the transport system, in this embodiment, the iron receiving lines 2 under the blast furnace casthouse 1 are arranged in parallel on one side of the molten iron transport trunk line 4 .

Abstract

The invention discloses an ironmaking-steelmaking interface short distance melted iron transportation system. The system comprises a blast furnace tapping yard, an under furnace iron bearing wire, a melted iron transport artery, a reladling station, a reladling line and a lead track, wherein the melted iron transport artery, the reladling track and the lead track are connected in sequence, the under furnace iron bearing wire below the blast furnace tapping yard passes through a casting house connecting line and is merged into the melted iron transport artery, an alpha included angle is formed between a casting house connecting line and the melted iron transport artery towards one side of the reladling station, and the alpha is larger than or equal to 90 degrees and smaller than or equal to 180 degrees; according to the system, the whole traction transport of a melted iron transport heavy vehicle from the blast furnace tapping yard to the steelmaking reladling station is achieved, the transport distance between the blast furnace tapping yard and a steelmaking workshop is shortened in a maximum degree, and the temperature drop of the melted water is reduced; the operation steps and the operation time of engine start-stop can be effectively reduced, the transport operation efficiency is improved, and the system has good economic and social benefits.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to a short-distance molten iron transport system at the ironmaking-steelmaking interface. Background technique [0002] Molten iron transportation is an indispensable production link in the long-process iron and steel smelting process. Constrained by production technology and land use restrictions, the current transportation methods of molten iron in domestic iron and steel complexes include three types: railway transportation, road transportation and straddle-car transportation. Molten iron railway transportation has been widely used because of its mature technology, rich actual production experience, good production rhythm flexibility, safety and reliability, but at the same time, it is limited by the technical characteristics of railway transportation. The large area leads to scattered arrangement of ironmaking and steelmaking, which prolongs the transportation time of molt...
