Description
Technical field
The present invention relates to the process for making technical field, relate in particular to a kind of based on the online tank switching system on the desulfurizing iron line.
Background technology
The foundation of molten iron ladle pouring facility is mainly based on following two factors:
(1) blast-melted mismatch problem with tank and steely iron water pot;
(2) " a tank system " hot metal supply is adopted in workshop, solves hot-metal bottle and tank problem.
For the steelshop that adopts the desulfurizing iron facility, no matter take KR Desulfurization by stirring method or Desulfurization by injecting method, all need take to have the desulfurizing iron chassis of hydraulic pressure tilt functions, realize transportation and the tilt functions of hot-metal bottle.It is reinforced across interior that the molten iron ladle pouring facility is arranged in workshop, not only take reinforced across usable floor area, but also need to increase the one-time investment of molten iron weighing chassis, be worth steel mill reducing thinking aspect one-time investment and operating cost.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind ofly based on the online tank switching system on the desulfurizing iron line, meet the molten iron ladle pouring facility and arranged high requirement to the space, workshop, and reduced the construction investment of workshop to the molten iron ladle pouring facility.
For achieving the above object, of the present invention a kind of based on the online tank switching system on the desulfurizing iron line, comprise at least:
Be set up in the crane that is used for the suspended mobile hot-metal bottle in the high vacancy of factory building;
Be placed in the tank switching dust excluding hood that the facility floor place is used for carrying out the tank switching operation, this tank switching dust excluding hood connects a dust arrester;
The desulfurizing iron chassis that can shift out at tank switching dust excluding hood station place shift-in;
And, a static state railroad track scale is set below the tank switching dust excluding hood.
Preferably, but also be provided with the containment facilities of the desulfurizing iron chassis of a fixed placement in the tank switching dust excluding hood at described tank switching dust excluding hood place.
Beneficial effect of the present invention is:
1, this online tank switching system process characteristics of compact layout, reasonable, the scope of application is wider, not only applicable " a tank system " molten iron direct-furnish technique, also applicable blast furnace and converter hot-metal bottle mismatch problem;
2, layout on-line tank switching facility, not only reduced the one-time investment of molten iron ladle pouring facility, but also significantly expanded reinforced across usable floor area;
3, this scheme proposes a kind of online tank switching facility based on the desulfurizing iron line, and this tank switching facility is arranged on the desulfurizing iron line, utilizes the carrier of desulfurizing iron chassis as the hot-metal bottle slack tank, and static state railroad track scale is as the metering device before and after tank switching.This invented technology facility characteristics of compact layout, cost of investment is low, operating cost is lower, not only is fit to newly-built workshop technology arrangement, but also be fit to the steelshop reforming technology, arranges that good application prospect is arranged.
Description of drawings
Fig. 1 is the described technology arrangement figure based on the online tank switching system on the desulfurizing iron line of the embodiment of the present invention.
The specific embodiment
The present invention will be further described below in conjunction with Figure of description.
As shown in Figure 1, the embodiment of the present invention is described a kind of based on the online tank switching system on the desulfurizing iron line, at least comprise control module, mobile performance element, and the desulfurizing iron chassis that is connected in described mobile performance element, be connected in the crane of described mobile performance element, be connected in the dust arrester of described mobile performance element, described dust arrester connects a tank switching dust excluding hood; One static state railroad track scale is set below the tank switching dust excluding hood.Described control module is mainly used in sending the control of equipment moving operation, and mobile performance element is mainly to chassis, and the mobile equipment of the needs such as crane moves.
Arrange one overheadly in factory building, crane is set on overhead.One tank switching dust excluding hood is set on the factory building bottom surface, the tank switching dust excluding hood connects a dust arrester, is used for dedusting when the tank switching molten iron.One static state railroad track scale is set below the tank switching dust excluding hood.In addition, but also be provided with the containment facilities of the desulfurizing iron chassis of a fixed placement in the tank switching dust excluding hood at described tank switching dust excluding hood place.
The operation principle of native system is:
When the molten iron ladle pouring operation need to be carried out in workshop, desulfurizing iron chassis 2 was left to the interior tank switching station of tank switching dust excluding hood 3 from the desulfurization station, and dust arrester 6 starts thereupon.At this moment, the desulfurizing iron chassis 2 that 4 pairs of static state railroad track scales are equipped with sky hot-metal bottle 7 carries out static weighing one time, after weighing finishes, the hot-metal bottle that the interior casting crane 1 of main building will be equipped with molten iron carries out the tank switching operation, the flue dust that the tank switching process produces is fully absorbed by dust arrester 6, after tank switching finished, 4 pairs of static state railroad track scales were equipped with desulfurizing iron chassis 2 and carry out the secondary static weighing, and the difference of twice weighing is the weight of molten iron in hot-metal bottle.After weighing finished, desulfurizing iron chassis 2 was left, and dust arrester 6 cuts out, and can select three process routes this moment:
(1) casting crane hangs out hot-metal bottle, can directly be blended into converter;
(2) casting crane hangs out hot-metal bottle, leaves in reinforced across interior wait temporarily;
(3) the desulfurizing iron chassis under weight of molten iron, composition, the satisfactory precondition of temperature, moves to the desulfurization station and carries out the molten iron pre-treatment job.
This scheme proposes a kind of online tank switching facility based on the desulfurizing iron line, and this tank switching facility is arranged on the desulfurizing iron line, utilizes the carrier of desulfurizing iron chassis as the hot-metal bottle slack tank, and static state railroad track scale is as the metering device before and after tank switching.This invented technology facility characteristics of compact layout, cost of investment is low, operating cost is lower, not only is fit to newly-built workshop technology arrangement, but also be fit to the steelshop reforming technology, arranges that good application prospect is arranged.
Above; be only preferred embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
