Description
Technical field
The utility model relates to a kind of logistics transportation system of smelting iron and steel industry, belongs to metallurgical technology field.
Background technology
Inner in iron and steel enterprise, in recent years, logistics transportation causes the concern of each enterprise gradually.All there is important direct impact the aspects such as transportation technology technology and the whether reasonable height for initial cost of scheme, enterprise's production scheduling difficulty or ease, the height of logistics cost, the size of energy loss.
Main for the Molten Iron Transportation between blast furnace-converter below.Currently used Molten Iron Transportation method mainly comprises following several.
First Automobile Transportation method, the method utilizes crane to hang onto on Molten Iron Transportation automobile by iron bag, empty iron contracted affreightment is accepted molten iron to blast furnace discharge yard by automobile, after iron bag weight of molten iron reaches requirement, transported to steelshop by automobile, the sky bag after iron is converted in converter transports blast furnace to by automobile again and accepts molten iron.Automobile Transportation is adopted to need to arrange special heavy-load road and keep good roadupkeep; The automobile of transport molten iron belongs to special vehicle, aims at Molten Iron Transportation and manufactures and designs, require higher security, reliability.
But mainly there is its own shortcomings in this Automobile Transportation method:

(2) use limits by containing amount: domestic employing automobile carries out enterprise's iron containing amount of Molten Iron Transportation all at below 150t, design, manufacture and use transport iron containing amount 150t are less with the experience of getting on the car, and limit the use of this Technology in large integrated enterprise.
(3) there is certain potential safety hazard: the impact that Road transport is subject to the natural condition such as ice and snow exists certain potential safety hazard; Vehicle ramp, bend etc. in transportation may cause molten iron, scum is splashed; Iron bag such as to burn at the harsh conditions, and the loss of life and personal injury such as driver and equipment may be caused to damage.
In view of above reason, current Automobile Transportation mode is not the main flow Molten Iron Transportation mode in steel industry.
Its two be utilize crane and molten iron transhipment across transport, as shown in Figure 1, the method utilize crane sky bag is put into blast furnace casting after the match iron hired car on, wait is tapped a blast furnace, this iron hired car in orbit walk, motor drive; After this iron iron clad water yield reaches requirement, iron hired car molten iron transported to molten iron transhipment across; Utilize crane to be hung by molten iron toward the iron hired car on molten iron transition line, transport molten iron to steelshop; Utilize steelshop crane to sling to transport converter to and convert iron; Convert the sky bag after iron hang onto transition line iron hired car on, transport to molten iron transition across; Utilize transition sky bag to be hung onto blast furnace casting after the match on iron hired car across crane, empty contracted affreightment is waited under blast furnace discharge yard and taps a blast furnace.
But this utilizes crane and molten iron transhipment mainly to there is its own shortcomings across the method for transporting:
(1) invest high: need build 1 across or 2 across weight across factory building, and need additional configuration some large-tonnage heavy metallurgy lifting machines, and total figure takes up an area larger;
(2) running cost is high: the molten iron turnover time is long, and temperature drop is large; And due to the method need molten iron transition across employing crane transport, the basis of horizontal transport adds the displacement of short transverse, need power consumption be produced; The lifting of lifting and the packet procedures crane that falls creates the extra activity duration, causes the temperature drop of molten iron or empty bag, finally can cause the temperature drop that Molten Iron Transportation link is larger;
(3) use limitation: for the Steel Complex of the multiple steelshop of planning, be difficult to adopt the method to organize Molten Iron Transportation.
Therefore, develop a kind of logistics transportation system of smelting iron and steel industry, be still one of this area problem demanding prompt solution.
