Abstract
The utility model discloses an argon blowing/oxygen blowing liquid steel refining device with a vacuum enclosure. The argon blowing/oxygen blowing liquid steel refining device comprises a steel ladle for loading liquid steel and a vacuum impregnation enclosure which is arranged above the steel ladle and is capable of lifting freely, wherein during working, the vacuum impregnation enclosure descends to enter the steel ladle so that a narrow airtight space is formed between the vacuum impregnation enclosure and the liquid level of the liquid steel. An inclined pipeline is connected above the vacuum impregnation enclosure; an extraction opening is formed on the pipe body of the inclined pipeline; a feeding system is connected to the end part of the inclined pipeline. The vacuum impregnation enclosure is modified from an impregnation enclosure, and then can be connected with a small mechanical vacuum pump; a vacuum degree is obtained in the narrow space and various types of refining of liquid steel can be finished under vacuum.
Description
Technical field
The utility model relates to vacuum refining device, is specifically related to a kind of vacuum (-tight) housing Argon oxygen blast refined molten steel device.
Background technology
Sealed argon-blowing oxygen blast regulates composition device (CAS-OB), is one of external refining equipment of large-scale iron and steel enterprise use always.
But it does not have vacuum metling function, therefore can not effectively bring into play vacuum-oxygen decarbonizing effect; If need to smelt function, must use high-power vacuum pump, will treat that smelting device is evacuated, but so, will expend large energy, greatly increase smelting cost.
Utility model content
The purpose of this utility model is to provide a kind of reliable working performance, cost is low, stable, the vacuum (-tight) housing Argon oxygen blast refined molten steel device (VCAS-OB) that efficiency is high, impregnating cover is transformed into into vacuum impregnating cover, it is connected with small-sized machine vacuum pump, at narrow space, obtains vacuum tightness, complete the various refinings to molten steel under vacuum.
For achieving the above object, the technical solution of the utility model is as follows:
An Argon oxygen blast refined molten steel device, comprising:
One for carrying the ladle of molten steel,
One arranges ladle top, and the vacuum impregnation cover of free lifting, and during work, vacuum impregnation cover declines and enters in ladle, makes to form between vacuum impregnation cover and molten steel liquid level a narrow and small enclosed space.
In a preferred embodiment of the present utility model, described vacuum impregnation cover top connects a tilted tube, and a bleeding point is set on the pipe shaft of described tilted tube, and the end of tilted tube connects a feed system.
In a preferred embodiment of the present utility model, described bleeding point connects a vacuum pump by a pump-line.
In a preferred embodiment of the present utility model, also comprise an oxygen lance lifting system, described oxygen lance lifting system comprises a vertical oxygen rifle inserting in vacuum impregnation cover, described oxygen rifle connects an oxygen supply device.
In a preferred embodiment of the present utility model, at ladle downside, one argon gas import is also set, argon gas enters in molten steel by argon gas import.
By technique scheme, the beneficial effects of the utility model are:
1, use vacuum impregnation cover to form narrow and small enclosed space.
2, use small-sized water ring oil-sealed rotary pump, vacuum system is simple.
3, the refining such as vacuum argon blowing, oxygen blast, decarburization, intensification.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is structural representation of the present utility model.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to Fig. 1, a kind of vacuum (-tight) housing Argon oxygen blast refined molten steel device (VCAS-OB), this system is comprised of ladle 1, vacuum impregnation cover 2, impregnating cover jacking system 3, feed system 4, oxygen lance lifting system 5, vacuum pump 6, pump-line 7 etc.
Also comprise an oxygen lance lifting system 5, oxygen lance lifting system 5 comprises a vertical oxygen rifle 8 inserting in vacuum impregnation cover, and described oxygen rifle 8 connects an oxygen supply device.
At ladle 1 downside, one argon gas import 101 is also set, argon gas enters in molten steel by argon gas import 101.
Refining process is as follows:
Vacuum impregnation covers under the drive of jacking system, inserts certain depth in the ladle have molten steel, makes to form between vacuum impregnation cover and molten steel liquid level a narrow and small enclosed space.Start vacuum pump, this narrow and small enclosed space is evacuated to 26kPa, and keep.The molten steel of enclosed space is carried out to Argon stirring, even molten steel temperature, composition; Cleaning molten steel;
Can prevent that molten steel is air-breathing; Can finely tune composition by vacuum charging; Can vacuum oxygen, make itself and reactive aluminum, carry out chemical heating; Can carry out vacuum-oxygen decarbonizing, reach vacuum refinement object.
VCAS-OB compares with CAS-OB, and the former has expanded the latter's function, especially has vacuum refinement function.
VCAS-OB compares with VOD, there is equally vacuum decarburization function, but the former vacuum space is little a lot, can use small-sized machine vacuum pump, can effectively reduce energy consumption, reduce the off-set facility of general Steam Ejector System, as built boiler house, cold water pump house, hot water pump house, steam-pipe, cooling water pipeline, high vacuum pump house etc.The cost of investment of VCAS-OB is lower.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
