Description
Technical field
It the utility model is related to a kind of blowing type tundish covering flux adding apparatus of continuous casting of iron and steel technical field.
Background technology
Tundish Covering Flux for Continuous Casting, which can play, to be improved Molten Steel Cleanliness, reduces molten steel temperature drop and prevent molten steel and air from connecing
Touch and produce the effect such as secondary oxidation.In casting cycle, it is indefinite that operating personnel need the coverage condition of molten steel according to coverture
When add tundish covering flux, prevent that molten steel is exposed.At present, sheet billet continuous casting process tundish covering flux is more using manually
The method of addition, i.e., throw into the coverture of whole bag in tundish.This method is time-consuming, laborious, operating personnel close to high-temperature molten steel,
There is security risk；Meanwhile coverture is manually thrown away, in whole bag coverture is fallen into bag, the liquid above Metal in Tundish can be broken
State coverture protective layer, causes molten steel and air contact, oxidation by air and pollute；In addition, the coverture of whole bag can be to molten steel
Face produces disturbance, the non-metallic inclusion of the top of the slag is entered in molten steel, forms inclusion defects, influence Molten Steel Cleanliness.
The Chinese patent of Patent No. CN201320328864.7《For adding the device of tundish covering flux》, it is grid
Shape stent is placed on tundish sealing cover and in impact bore region, staff is covered tundish using clamping device
After agent is sent to grid, the scaling loss using molten steel face hyperthermia radiation to tundish covering flux packaging bag, falls tundish covering flux
Enter impact zone.The shortcoming of the device is：(1) latticed stent, which is located at middle backpack cover impact bore region, can influence worker to centre
The thermometric of Baogang's water and sampling；(2) connect to pour every time and worker's installation ladle long nozzle can be influenced when changing ladle；(3) coverture is packed
The scaling loss of bag has a process, can influence the timely addition of coverture.
Therefore, it is necessary to which developing one kind not only can guarantee that tundish covering flux smoothly added in time, but also it can make worker is convenient to grasp
The tundish covering flux adding apparatus of work.
Utility model content
The purpose of the utility model is to overcome prior art defect, there is provided a kind of blowing type tundish covering flux adds dress
Put.
What the technical solution of the utility model was realized in：Blowing type tundish covering flux adding apparatus, by feed bin, gives
Expects pipe, compressed air hose, mixing tube, metal hose, spray gun composition, bin bottom are connected with mixing tube by feed pipe, mixed
Materials in the tube stream is connected with compressed air hose in the reverse direction, is blowed to stream by compressed air soft with the metal that is connected of mixing pipe end
Pipe, metal hose other end connection spray gun, middle bag is sprayed to by spray gun by coverture stream.
Further, lance outlet end is bent downwardly connection spray gun spray nozzle in 90 °, and spray gun spray nozzle sprays for 360 ° of circular seam types
Head, nozzle are covered with circular mantle, and coverture is steadily covered in centre from the free-falling under the stop of outer cover after circumferential weld ejection
On Baogang's liquid level.
Further, valve is equipped with feed pipe, solenoid valve is equipped with compressed air hose, operation handle is equipped with spray gun,
Controlling switch of the operation handle equipped with control solenoid valve, the control circuit of solenoid valve are fixed on the outside of pipeline.
Further, material position monitor is equipped with feed bin.
Further, it is fixed with gun stand in tundish platform relevant position.
The utility model timely and accurately can add coverture to tundish, to molten steel almost without disturbing in adition process
Dynamic, Metal in Tundish Control and Inclusion Removal level is significantly improved, and significantly reduces labor strength.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure, 1- feed bins；2- material position monitors；3- valves；4- compressed air hoses；5- solenoid valves；6- feed pipes；7- is mixed
Pipe；8- metal hoses；9- operation handles；10- controlling switches；11- gun stands；12- spray gun spray nozzles；13- outer covers.
Embodiment
It is further described below in conjunction with the accompanying drawings：
As shown in Figure 1, blowing type tundish covering flux adding apparatus, by feed bin 1, feed pipe 6, compressed air hose 4, mixing
Pipe 7, metal hose 8 and spray gun composition, 1 bottom of feed bin are connected by feed pipe 6 with mixing tube 7, and 7 stream of mixing tube is in the reverse direction
Compressed air hose 4 is connected with, stream is blowed to by the metal hose 8 being connected with 7 end of mixing tube, metal hose by compressed air
8 length determine that 8 other end of metal hose connects spray gun, during coverture stream is sprayed to by spray gun according to use site is actual
Bag；
Lance outlet end is bent downwardly connection spray gun spray nozzle 12 in 90 °, and spray gun spray nozzle 12 is 360 ° of circular seam type nozzles, nozzle
Circular mantle 13 is covered with, coverture is steadily covered in tundish from the free-falling under the stop of outer cover 13 after circumferential weld ejection
On molten steel face, the interference of blowing gas and coverture to liquid steel level can be prevented, while coverture is added with being uniformly dispersed；
