Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1: the embodiment discloses a take end casting formula ladle of argon blowing device at bottom, including the ladle body, the ladle body includes ladle inside lining 5 and sets up in ladle shell 7 of 5 outside of ladle inside lining, on the basis of above-mentioned current ladle body, the bottom of this embodiment ladle body is equipped with air brick 1 and molten steel export 3, and air brick 1 switches on in argon gas feeding device 6 through pipeline 2, and argon gas feeding device 6 optional steel bottle.
The gas permeable brick 1 belongs to the prior art, and has a special structure that only gas can pass through the gas permeable brick, but molten steel cannot pass through the gas permeable brick.
The molten steel outlet 3 is provided with a discharge control device for controlling the opening and closing of the molten steel outlet 3, the discharge control device of the embodiment is a molten steel outlet stopper 4 matched with the molten steel outlet 3, and the matching means that the end part of the molten steel outlet stopper 4 can realize the opening and closing of the molten steel outlet 3. And the molten steel outlet stopper 4 is connected with a stopper driving device for driving the molten steel outlet stopper 4 to move relative to the molten steel outlet 3. The stopper rod driving device can be any one of the prior art, for example, the stopper rod 4 of the molten steel outlet can be driven to move relative to the molten steel outlet 3 by a lead screw.
Because the ladle body includes ladle inside lining 5 and ladle shell 7, wherein ladle inside lining 5's main function is isolated heat, and ladle shell 7 has then guaranteed the intensity of whole ladle body, air brick 1 inlays in the bottom of ladle body, need bear certain load, in order to avoid air brick 1 and ladle inside lining 5 to break away from or damage in the use, the lateral part of this embodiment air brick 1 is connected in ladle inside lining 5, its lower extreme is connected in steel cladding 7, promote joint strength and the leakproofness between air brick 1 and the ladle inside lining 5 through the support of steel cladding 7.
Furthermore, pipeline 2 is directly connected in air brick 1, then probably damages air brick 1 in the in-process that uses, and in order to avoid this phenomenon, this embodiment is best with the air brick link of pipeline 2 again in the ladle shell 7 that is in air brick 1 lower extreme position, can fix pipeline 2 like this, avoids pipeline 2 to be damaged air brick 1 by accidental collision.
Because the argon gas is through the inside of air brick 1 dispersion diffusion to the molten steel, in order to make the argon gas can be abundant, enter into the inside to the molten steel evenly, promote the dispersion degree of argon gas in the molten steel, this embodiment air brick 1 sets up the central point in ladle body bottom best, molten steel export 3 sets up the non-central point in ladle body bottom so, molten steel export 3's position height can be a little lower, 3 last highly being less than the upper surface of ladle inside lining 5 of edge of molten steel export promptly, avoid the molten steel to appear remaining.
When the device is used, molten steel is positioned in the steel ladle body, argon in the argon supply device 6 enters the air brick 1 through the pipeline 2, the dispersed bubbles which are small in size are formed under the diffusion effect of the air brick 1, then enter the molten steel and float upwards, and in the floating process of the dispersed bubbles, various types of micro-particle impurities suspended in the molten steel are brought to the surface of the molten steel. Furthermore, the coating is also eroded to produce MgO and Al2O3And adsorbed N2、H2And the harmful elements are brought to the surface of the molten steel. After the molten steel is purified, the molten steel is poured into a model through a water gap at the bottom of a ladle, and harmful waste slag brought to the surface of the molten steel by argon is not contacted.
In practical operation, the amount of argon and the discharge rate can be configured according to practical situations.
Compared with the prior art, the embodiment adopts the mode of introducing argon to remove various microparticle impurities, MgO and Al in molten steel2O3And adsorbed N2、H2Harmful elements float up to the upper surface of the molten steel, and the molten steel flows out from the molten steel outlet 3 at the bottom, so that the residues floating on the surface cannot enter the next process.
Argon gas enters into the inside of molten steel through the diffusion effect of air brick 1, decomposes the positive little argon gas group of argon gas decomposition body, has promoted the diffusion degree of argon gas on the one hand, makes it diffuse in the inside of molten steel as far as possible, moreover, has also saved the use amount of argon gas.
The argon belongs to inert gas, and the argon can not react with the molten steel, so that the pollution to the molten steel is avoided.
Except purifying the molten steel, because of adopting the bottom casting formula ladle, the molten steel flows out from the discharge gate of bottom, avoids floating the residue on the molten steel upper surface to get into the model and recontaminate, has also promoted the quality of product, because the collection of residue.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
