Description
Technical field
The present invention relates to one tank technical field of steel-making, specially a kind of vanadium-titanium-iron-water transports a tank technology.
Background technique
It just can enter steel-making preprocessor after steel-making needs " turning over molten iron " due to smelting iron ladle at present, according to 10-
Molten iron temperature data statistics in November molten iron in October turns over preceding 1345 DEG C of the temperature of packet, molten iron in November turns over 1330 DEG C of temperature before packet,
Molten iron turn over packet after to desulfurization stirring when molten iron mean temperature at 1295 DEG C or so, hot metal temperature drop is blast-melted up to 42.5 DEG C or so
Single packet weight of molten iron is wrapped between 35-40t, hot metal in steelmaking packet list packet converter demand is between 73-78t, after causing molten iron to turn over packet
There is remaining iron or the inadequate situation of charge weight is serious, because Yu Tie or charge weight are inadequate, " packet not enough, two be surrounded by remaining ", with old area
Smelting strength of blast furnace increases, and blast furnace production capacity increases, and stokehold averagely puts iron number 6~7 times, and blast furnace is put not empty, influences production capacity and mentions
It rises.
To solve these problems, it and realizes the unified use of hot-metal bottle between old area blast furnace and old area steel-making, that is, smelts iron
Molten iron is sent to steel-making after filling, no longer turn over molten iron, is directly entered preprocessor, the technology of " a tank system ", the technology occurs
The intermediate process for carrying out tank switching iron making in conventional procedure is eliminated, steel-refining water pot is directlyed adopt to blast furnace and accepts molten iron, be one
By the functions together as one such as blast-melted undertaking, transport, buffer reservoir, molten iron pretreatment, converter iron making and hot-metal insulating
Novel technique, " a tank system " technique has that process flow is short, the simplification of production operation link, total figure characteristics of compact layout, molten iron temperature
The advantages that small, smoke discharge amount is few, drops.
But not high enough, existing a large amount of old area steel mills are promoted in the transport in existing " a tank system " technology, it is difficult
With the large-scale redevelopment operation of implementation " tank is on earth ", and the existing transporting equipment of steel mill and transportation means is used to be transported
Defeated, the speed of transport and the total amount of transport are all difficult to meet higher steel-making demand, and still there are many details for existing means
Need it is perfect, so propose that a kind of vanadium-titanium-iron-water transports a tank technology to solve the problems, such as above-mentioned propose.
Summary of the invention

The existing tractor of flatcar collocation uses, and ladle transports directly to old area steel-making after filling molten iron, is no longer pass through molten iron " turning over packet "
Process carries out " a tank system " technology of existing popularization；
2) it is transformed on the flatcar bought, adds ladle capping mechanism, Weighing mechanism and braking mechanism, molten iron
Packet capping mechanism can be obtained using mechanical arm via simple transformation, and support mechanism and braking mechanism can directly be bought, the iron on flatcar
Two hanging axis center of water pot is not changed away from 3620, and hanging device does not change, and plate hook does not change；
3) civil engineering transformation is carried out to steel mill, removes road side facility, broadening processing is carried out to road, headroom is insufficient
When, corresponding establishment is rebuild；
4) in the same installing molten iron capping mechanism in flatcar two sides, ladle quickly add by molten iron capping mechanism
Lid, decorates installing Weighing mechanism in each ladle, is quickly examined by Weighing mechanism to the weight of molten iron that ladle loads
It surveys, cooperates tractor to carry out brake operation by braking mechanism.
Preferably, the flatcar turning radius is 50 meters minimum.
Preferably, the tractor is diesel locomotive, and one of model JMY154 and JMY175, coupler centre is extremely
Rail level height 880mm, does not change.
Preferably, the road outer dimension requirement: motorcycle track passage width is not less than 4.2 meters, and headroom is not low
In 4 meters.
(3) beneficial effect
Compared with prior art, the present invention provides a kind of vanadium-titanium-iron-waters to transport a tank technology, has following beneficial to effect
Fruit:
The vanadium-titanium-iron-water transports a tank technology, in the case where not changing layout between blast furnace and steel-making, passes through place
Transformation and flatcar transformation, the advantages of further strengthening a tank, reduce to being laid out the height being transformed between blast furnace and steel-making
Investment, and can satisfy the production capacity demand of steel mill, it avoids conventional means transport one tank technology of progress and inefficiency occurs
The phenomenon that, in extensive place, transformation and existing old workshop are difficult to seek between the status being transformed to the technical side more balanced
Case, the hot-metal bottle facilitated between old area blast furnace and old area steel-making use, realize and promote higher purpose, renovation technique is more
Add convenient and simple.
