Abstract
The invention discloses a novel argon gas protecting device for die casting. According to the novel argon gas protecting device for die casting, argon gas can effectively prevent steel streams from making contact with air, so that the effect of protecting pouring is achieved. According to the technical scheme, one end of a gas inlet pipe (1) of the novel argon gas protecting device for die casting is connected with an annular gas chamber (3), the other end of the gas inlet pipe is connected with an external argon gas pipe, an iron sheet cover (6) is arranged outside the annular gas chamber (3), three fixing grapnels (2) are welded along the circumference of the outer surface of the iron sheet cover (6) at equal intervals, small argon blowing holes (5) are evenly distributed in the lower wall of the annular gas chamber (3), an annular crack (4) is formed in the outer side wall of each small hole (5), a sliding plate mechanism (9) is installed in a collector nozzle (10), corresponding to each crack, at the bottom of a steel ladle, and a groove (7) is reserved in the lower portion of each sliding plate mechanism (9). The novel argon gas protecting device for die casting has the advantages that the structure is novel, the operation is simple, and the bottom of the steel ladle is in seamless connection with the argon gas protecting device, so that the protecting effect is good; an argon blowing opening of the annular argon gas chamber is jointly formed by the evenly-distributed small holes and the annular cracks, therefore, the blocking probability caused by liquid steel is greatly lowered, and the service life is prolonged; the novel argon gas protecting device is made of steel, and therefore the novel argon gas protecting device can be reused and is low in cost.
Description
Technical field
The invention belongs to the die casting argon protective device, be specifically related to a kind of novel die casting argon protective device.
Background technology
The cast argon protective device generally all is the steel pipe of fixing an annular around collector nozzle of ladle at present, the external tunger tube of this steel pipe; the bottom of steel pipe is uniform-distribution with aperture; argon gas blows out from the top down from aperture and forms the argon gas air curtain, and steel stream prevents secondary oxidation in the protection cast.In order to prevent the impact of air curtain receipts Air Flow, the ceramic fiber cloth that makes a circle around the steel pipe of annular falls to feed trumpet protection argon gas air curtain from the lower mouth of a river.Above-mentioned technology exists lower column defects: the one, and the Argon aperture of steel pipe below is blocked by the slag of splash easily, needs often to change; The 2nd, the weather screen of ceramic fibre is burnt easily, and can not change in the casting process, the protection weak effect, and the ceramic fiber cloth cast is once changed one in addition, and cost is high.
Summary of the invention
For the weak point that prior art exists, the present invention discloses a kind of novel die casting argon protective device, and novel die casting argon protective device structure makes argon gas can effectively prevent steel stream and contact with air, plays the effect of protection cast.
Above-mentioned purpose is achieved through the following technical solutions, and novel die casting argon protective device reaches the sled mechanism ⑼ that mouth of a river ⑽ installs under the supporting with it ladle bottom by air inlet pipe ⑴, ring-like gas chamber ⑶, iron sheet cover ⑹ and consists of.
The end of described air inlet pipe ⑴ links to each other with ring-like gas chamber ⑶, and the other end joins with the tunger tube of outside;
The described ring-like gas chamber ⑶ lower wall Argon aperture ⑸ that evenly distributes, aperture ⑸ lateral wall is offered a ring-type finedraw ⑷;
Be truncated on the described iron sheet cover ⑹ and be truncated under cylindric horn-likely, it is outside that the upper section cylindrical portion of iron sheet cover ⑹ is divided in ring-like gas chamber ⑶;
Three of the outer surface welding of upper section circular cylinder shaped portion of described iron sheet cover ⑹ are grapple ⑵ fixedly;
Described three fixedly grapple ⑵ along upper section cylindric iron sheet cover ⑹ outside circumference all apart from distribution;
Groove ⑺ is reserved in the bottom of described sled mechanism ⑼.
The present invention has the following advantages: novel structure, and simple to operate; The seamless link of ladle bottom and argon protection device is protected effective; The argon blowing hole of ring-type argon gas chamber is made of jointly equally distributed aperture and ring-type finedraw, greatly reduces because molten steel causes the probability that blocks, has improved service life; Made by iron material, but Reusability, and cost is low.

Icon: air inlet pipe 1, fixedly grapple 2, ring-like gas chamber 3, finedraw 4, aperture 5, iron sheet cover 6, groove 7, ladle 8, sled mechanism 9, the lower mouth of a river 10, die casting argon protective device 11, funnel brick 12, feed trumpet 13.
The specific embodiment
As shown in Figure 1, an end of the air inlet pipe 1 of novel die casting argon protective device links to each other with ring-like gas chamber 3, and the other end joins with the tunger tube of outside; Ring-like gas chamber 3 is welded by the trumpet-shaped iron sheet 6 of inner machined piece and outside; The equally distributed φ 4mm of ring-like gas chamber 3 lower walls Argon aperture 5, aperture 5 lateral walls are offered a ring-type finedraw 4, and aperture 5 is worked (seeing Fig. 2) simultaneously with finedraw 4 during Argon, satisfies for the argon amount; Be truncated on the iron sheet cover 6 and be truncated under cylindric horn-likely, three of the outer surface welding of upper section circular cylinder shaped portion of iron sheet cover 6 are grapples 2 fixedly.
As shown in Figure 2, three fixedly grapple 2 along upper section cylindric iron sheet cover outside circumference all apart from distribution; The mouth of a river 10 is equipped with sled mechanism 9 under the ladle bottom, and groove 7 is reserved in sled mechanism 9 bottoms.
As shown in Figure 3, when using die casting argon protective device 11, fixing grapple 2 is installed in the groove 7 of sled mechanism 2, rotates to an angle and just can fix, installation is very convenient; The iron sheet cover is cut horn-like the lid on feed trumpet 13 tops 6 times, and the lower port diameter of trumpet-shaped iron sheet 6 is larger than the upper diameter of feed trumpet 13, can cover closely feed trumpet; In order in cast, to observe the state of steel stream, offer the window of a 30mm * 100mm at iron sheet cover 6.Because protective device top is directly installed on the sled mechanism 2, the bottom is directly covered on feed trumpet 6, realizes the feed trumpet mouth of a river 10 hermetically sealed under the ladle bottom.
