Abstract
The utility model relates to a steel-smelting blowing argon device. In order to solve the steel-smelting blowing argon structure, the utility model discloses a mold-filling argon protecting device. The mold-filling argon protecting device is characterized in that the mold-filling argon protecting device is arranged on the drainage port of the ladle. The mold-filling argon protecting device consists of an intake pipe, an annular air chamber, a fixing clip plate, a guide plate, an air out distribution pipe, a uniformly distributed air intake and a uniformly distributed air outlet. The direction of the air outlet is toward down. The air curtain direction is the same with the flow of steel from top to bottom, witch prevents the flow of steel contacting the air and the quality of the ingot is ensured. The difficulty that the clear headway of the ladle hung by the running car is insufficient in the pouring process is solved. The traditional structure and mounting position are changed. The utility model has the advantages of novel structure, low cost, easy and simple operation. The utility model is made of iron material and can be used repeatedly.
Description
Technical field
The utility model relates to the device that the steel-making Argon is used.
Background technology
Annotating at present and water middle argon shield structure, generally all is to install an argon seal of making of refractory material on the basin brick of feed trumpet additional, and the argon seal is from the following mouth of a river close together of its top steel ladle sliding water gap.Open an aperture in the front of argon seal and insert external tunger tube, argon gas circulation in circle forms air curtain during cast, carries out the horizontal blowing argon.Panzhihua vanadium iron steel mill is annotated the argon shield structure to mould and has been done improvement, on argon seal inwall tracheae is set, and the pipe upper surface has uniform small pores, and external argon rifle forms column air curtain upwards.Above-mentioned prior art ubiquity following defective; The one, air curtain protection from bottom to top with the steel flow path direction of cast to instead, cause argon gas to be brought in the mould by steel stream, causing that molten steel seethes in the mould influences ingot quality.Steel stream can not be surrounded fully when argon seals simultaneously, when molten steel is emitted, easily will cause cast nitrogen pick-up the airborne nitrogen suction molten steel in ladle; The 2nd, existing structure all is disposable use; The 3rd, install an argon seal additional on the basin brick of feed trumpet after, feed trumpet and the driving distance of hanging between the ladle are less, have limited the cast height, cause beam argon envelope difficulty.
Summary of the invention
Exist weak point at prior art, for solving steel-making Argon structure, the utility model provides a kind of mould to annotate argon protective device.It can play the effect of argon for protecting pouring effectively, prevents that steel stream from contacting with air.
The utility model is to realize by following technical scheme, it comprises air inlet pipe, its structural feature is that an end of air inlet pipe links to each other with the ring-type air chamber, the other end joins with outside tunger tube, the circumference between two disks up and down of ring-type air chamber is provided with the ring-type distributor pipe of giving vent to anger, the ring-type distributor pipe of giving vent to anger fuses with two disks up and down, the two disk medium pores up and down of ring-type air chamber link to each other with fixing chuck plate, import department in the ring-type air chamber is provided with deflector, the inboard middle of distributor pipe of giving vent to anger is provided with uniform air admission hole, and the distributor pipe lower end of giving vent to anger is provided with uniform venthole.
Above-mentioned venthole accumulation area is 1 with the ratio of air inlet pipe sectional area: 0.6-0.9.
Above-mentioned uniform air admission hole and uniform venthole can be the ring-type finedraws.
The utility model adopts installs mould notes argon protective device on the following mouth of a river of ladle, changed traditional Argon structure and installation site, has solved the difficulty of casting process middle rolling car handling ladle head room deficiency.This device disk race diameter is greater than feed trumpet basin brick, venthole down, the air curtain direction is identical with the steel flow path direction from top to bottom, has prevented that steel stream from contacting with air, has stopped that molten steel seethes in the mould that molten steel causes because of argon gas is brought into, can ensure ingot quality.This apparatus structure novelty is made by iron material, can use repeatedly, and cost is low, and is easy and simple to handle.
Description of drawings
Fig. 1 is the utility model installation site schematic diagram.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below with reference to drawings and Examples.
Among Fig. 1, feed trumpet 1, basin brick 2 (cast gate), ladle 5, the following mouth of a river 4, mould is annotated argon protective device 3 and is installed in down on the sleeve at the mouth of a river 4 by the fixing chuck plate on it.This device 3 not taking driving and hanging free space between ladle and feed trumpet, pourable various ingot shapes owing to directly be contained under the ladle on the mouth of a river.
Among Fig. 2, the fixing chuck plate 6 that mould is annotated argon protective device has been connection effects, and this device is contained on the following mouth of a river of ladle, and this mould is annotated argon protective device and is fabricated from iron, and can use repeatedly.Air inlet pipe 7 is joined with tunger tube, and ring-type air chamber 8, this air chamber 8 are used for homogenizing air pressure.The annular distributor pipe 9 of giving vent to anger fuses on two disks up and down of ring-type air chamber 8 and the circumference, and the two disk medium pores up and down and the fixing chuck plate 6 of ring-type air chamber 8 connect together.The inboard middle of distributor pipe 9 of giving vent to anger has uniform air admission hole 11, and this air admission hole 11 can be split into the ring-type finedraw.Lower end at the distributor pipe 9 of giving vent to anger has uniform venthole 12, and venthole 12 directions are used for forming air curtain down.This venthole 12 can be split into the ring-type finedraw, and present embodiment all is split into the ring-type finedraw into and out of pore.Venthole 12 accumulation areas are 1 with the ratio of air inlet pipe 7 sectional areas: 0.6-0.9, the ratio of present embodiment is 1: 0.8.The purpose of this ratio is to make to have certain uniform pressure in the air chamber, could form the air curtain of equilibrium length like this along loop wire.Deflector 10 is equipped with in import department in the ring-type air chamber 8, plays shunting action, forms low-pressure area to prevent air inlet pipe 7 at ring-type air chamber 8 one ends.During work, the argon gas that is come by external argon rifle enters air inlet pipe 7, enters ring-type air chamber 8 by the deflector 10 in the ring-type air chamber 8, stablizes air pressure and form circulation in air chamber 8.Argon gas flows into the distributor pipe 9 of giving vent to anger through air admission hole 11 then, and the lower end venthole 12 from the distributor pipe 9 of giving vent to anger flows out again.Because this device race diameter is greater than feed trumpet basin brick, argon gas is identical with the direction of steel stream.Argon gas forms the splayed configuration air curtains downwards by lower production well 12 and surrounds molten steel, has prevented that air from entering and the molten steel nitrogen pick-up that causes and Mo Nei molten steel are brought into because of argon gas and caused and seethe.
