Abstract
The utility model discloses an ingot mould chassis. The ingot mould chassis comprises a chassis body, a middle injection pipe and an ingot mould as well as a runner, wherein the middle injection pipe and the ingot mould are arranged on the chassis; the runner is arranged inside the chassis and is connected with the middle injection pipe and the ingot mould; the runner is communicated with the bottom of the ingot mould through a rising hole; and an argon blowing device communicated with the ingot mould is arranged inside a body located at the bottom of the ingot mould and is used for blowing argon into the ingot mould. The argon is continuously and slowly blown when molten steel is injected into the ingot mould from the rising hole, so that various impurities in the molten steel are brought into the head of an ingot by rising of the argon from the bottom of the ingot mould. Therefore, the impurities can be removed by cropping the ingot, so that the ingot quality is improved.
Description
Technical field
The utility model relates to ingot mould, more particularly, relates to a kind of ingot mould chassis.
Background technology
Along with the continuous development of cast steel technology, continuous casting has become the main mode of modernized iron and steel enterprise STEELMAKING PRODUCTION.But die casting but has the meaning and the value of its existence as a kind of traditional cast steel technology, and different with continuous casting " flowing water " operation, die casting production has the advantage of intensively and carefully working out something.Not only in China, so some developed country in the world, still keep die casting and producing line.
Continuous development along with variety steel; The die casting product not only is confined to traditional capped steel; Progressively expand to T91,2Cr13, B30M, S135 drilling rod, spring steel, steel cord, axle steel, gas cylinder steel, thick plate steel, cold-forging steel, nuclear power with steel, stay cables of bridge with steel and Olympic Games project with die casting elaboration such as steel, therefore also more and more stricter to the requirement of quality.For the quality of continuous stable prod, the ratio that two refining (LF+RH) operations of die casting product are handled is also improving constantly, and being intended to fully degass is mingled with, the accelerating oxidation thing is mingled with come-up, improves the product internal soundness.
At present, existing ingot mould chassis is as shown in Figure 1, and when molten steel injected chassis body 2 from feed trumpet 1, molten steel flow into the rise hole 4 on both sides through body 2 inner passages 3, is fed directly to the ingot mould 5 from rise hole 4 then, is full of ingot mould 5 until molten steel.But because molten steel has the existence of each type impurity in smelting process, and when refining RH Argon treatment effect was not obvious, field trash just stockpiled in ingot mould 5, finally formed all kinds of defectives in the rolling back of steel ingot, and product quality is affected.
The utility model content
To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides a kind of ingot mould chassis, can carry out Argon to the molten steel in the ingot mould, can effectively improve the degree of purity of molten steel.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
This ingot mould chassis comprises chassis body, is located at feed trumpet and ingot mould on the chassis; Be located in the chassis and runner that connect feed trumpet and ingot mould; Runner is connected through rise hole with the ingot mould bottom; The described body that is positioned at the ingot mould bottom is provided with the Argon device that is connected with ingot mould, to carrying out blowing argon gas in the ingot mould.
Described Argon device comprises that Argon pipeline and ladle argon-blown use air brick, and air brick is located at respectively in the body of ingot mould bottom, and Argon pipeline one end links to each other with air brick, and the other end is connected to source of the gas.
Described air brick comprises brick seat, air brick core and gland, and the air brick core is located in the brick seat, and fixes through gland and body, ingot mould.
Described air brick core is located at a side of corresponding rise hole, and with its at a distance of 2cm.
In technique scheme, the ingot mould chassis of the utility model comprises chassis body, is located at feed trumpet and ingot mould on the chassis, is located in the chassis and runner that connect feed trumpet and ingot mould; Runner is connected through rise hole with the ingot mould bottom; The described body that is positioned at ingot mould bottom is provided with the Argon device that is connected with ingot mould, to carrying out blowing argon gas in the ingot mould, at molten steel continuous blowing argon gas slowly when rise hole is injected ingot mould; Bring each type impurity the molten steel into ingot head through argon gas from the rising of ingot mould bottom; Like this,, butt ingot just can improve the steel ingot quality to inclusion removal when being handled.
Description of drawings
Fig. 1 is the structural representation on the ingot mould chassis of prior art;
Fig. 2 is the structural representation on the ingot mould chassis of the utility model;
Fig. 3 is the cutaway view of the air brick of the utility model.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also Fig. 2～shown in Figure 3; What the ingot mould chassis of the utility model was identical with prior art is; Equally also comprise chassis body 2, be located at feed trumpet 1 and ingot mould 5 on the chassis; Be located in the chassis and runner 3 that connect feed trumpet 1 and ingot mould 5, runner 3 is connected through rise hole 4 with ingot mould 5 bottoms.Different is that the described body 2 that is positioned at ingot mould 5 bottoms is provided with the Argon device that is connected with ingot mould 5, to carrying out blowing argon gas in the ingot mould 5.Described Argon device comprises Argon pipeline 6 and ladle argon-blown with air brick 7, and air brick 7 is located at respectively in the body 2 of ingot mould 5 bottoms, and Argon pipeline 6 one ends link to each other with air brick 7, and the other end is connected to source of the gas.And the concrete structure of described air brick 7 comprises brick seat 8, air brick core 9 and gland 10, and air brick core 9 is located in the brick seat 8, and fixes through gland 10 and body 2, ingot mould 5.In addition, described air brick core 9 is located at a side of corresponding rise hole 4, and with its at a distance of 2cm.
During cast, molten steel is poured into chassis body 2 by feed trumpet 1, and get in the ingot mould 5 by rise hole 4 through runner 3; Simultaneously, in ingot mould 5, carry out slowly blowing argon gas, bring each type impurity the molten steel into ingot head from the rising of ingot mould bottom through argon gas through the brickwork joint of Argon device through air brick core 9; And play the effect that molten steel is stirred; Like this,, butt ingot just can improve the steel ingot quality to inclusion removal when being handled.
In sum, adopt ingot mould 5 chassis of the utility model to possess following advantage:
