Description
Technical field
The invention belongs to metallurgy iron, steel operation interface tech field, particularly the direct-connected technique in interface is smelted iron-made steel to one.
Background technology
In recent ten years, along with the high speed development of metallurgical technology, interface tech is more and more by the concern of metallurgy industry, between ironmaking-steel-making interface, " tank on earth " Molten Iron Transportation technique progressively instead of the production technique that traditional torpedo tank car carries out tank switching operation, increasingly mature along with " tank on earth " production technique between iron-making and steel-making operation interface, it is more and more obvious that its superiority embodies in Steel Plant produce, and blast-melted undertaking, transport, buffer reservoir, hot metal pretreatment, converter are converted iron, container and to be had enough to meet the need fast and the function such as hot-metal insulating integrates by its technology.Reduce molten iron ladle pouring operation, shortened process, compact total figure arranges, reduces hot metal temperature drop, reduces energy consumption and smoke contamination, have larger economy, environmental and social benefits.
The space layout at ironmaking-steel-making interface is also undertaken being connected by the railway system that traditional employing is huge and is changed to shorter victory, efficiently mode of transport.Space layout between ironmaking, steel-making interface, mode of transport, transportation equipment is also to development in pluralism, it in recent years, domestic newly-built Steel Plant almost all consider " tank on earth " production technique, but the how target pursued of more efficient, Duan Jieshi modern steel factory, the metering the spatial relation of arranging from ironmaking, steel making working procedure, mode of transport, transportation equipment, transport courses, buffering, the aspects such as the emergency processing under the locating and tracking of iron ladle, hot-metal car, accidental state are kept on improving.
Existing ironmaking-steel-making interface shape layout mainly contains two profiles formula:
(1) the huge railway system is adopted to realize the Molten Iron Transportation of iron, steel inter process.Railways Stations system, signalling system, dispatching system, dimension check system are set, Along Railway arrange pig-casting machine system, roasting system built by laying by iron ladle, locomotive servicing maintenance system etc., system complex, bring ironmaking, steel making working procedure distant, haul-cycle time is long, and hot metal temperature drop is large, and smoke contamination scope is large, the railway system takes up an area larger, the inferior positions such as staffing is many, and accident point is many, deviate from modern steel factory and pursue the target realizing good economic benefits, environmental benefit.
(2) adopt the transport of track haulage, lifting machine to instead of traditional transportation by railroad, ironmaking, steel making working procedure close together, layout is regular, but iron, steel inter process arrange iron ladle transhipment across, transition across, cushion across etc. too many levels operation.Cargo handling operation is more, iron ladle transhipment across, transition across etc. factory building be the transhipment realizing iron ladle, need configure large-tonnage lifting machine, the corresponding factory building load that brings is large, free height, and investment is large.
To sum up, need the shorter victory of one, efficiently ironmaking-steel-making interface arrangement technology, shorten the distance of ironmaking, steel making working procedure to greatest extent, reduce cargo handling operation, integrate by the production process of crane job, realize higher economic benefit and environmental benefit.
Summary of the invention
The object of the present invention is to provide a kind of ironmaking-direct-connected technique in steel-making interface, it is direct-connected that Molten Iron Transportation line is passed through in blast furnace ironmaking workshop and converter steelmaking workshop, molten iron adopts molten iron transportation vehicle direct sending to steelshop from crossing Molten Iron Transportation line by Tie Tong State of Blast Furnace, shorten the distance of ironmaking workshop and steelshop to greatest extent, change the enterprise schema that the huge railway system of traditional employing carries out Molten Iron Transportation, improve ironmaking-steel-making " tank on earth " interface adopt transition across, transport across, cushion the Molten Iron Transportation operation across waiting too many levels, reduce Molten Iron Transportation cargo handling operation, realize the short victory of Molten Iron Transportation to greatest extent with efficient, it is compact and regular that total figure arranges.
