Abstract
The utility model provides an argon seals ring canal for large castings, including ring canal body and argon gas union coupling head, the ring canal body include the convex core, water inlet, delivery port, slit cavity air chamber and bleeder vent, and the convex core uses the preparation of the fire -resistant material of aluminium carbonaceous. The beneficial effects of the utility model mainly reside in that: argon seals ring canal for large castings can provide bigger the argon protection the district for liquid metal's pouring process, provides more stable the argon protection, has effectually avoided the pollution of air to liquid metal, is of value to the internal soundness that improves large castings.
Description
Technical field
The utility model belongs to metallurgical auxiliary field, relates generally to a kind of heavy castings argon seal ring pipe.
Background technology
Heavy castings Metal Melting are smelt meet necessarily required liquid and water enter in casting mold, through cooled and solidified, level process after obtain the technical process of the foundry goods of predetermined shape, size and performance.In foundry goods process, liquid metal takes up ladle by one and to be injected into through the argon shield district that argon seal ring pipe is formed and to take up tundish.At present, as shown in Figure 1, most argon seal ring pipe uses iron sheet to make, and these both sides, inside and outside of endless tube are provided with air-vent.Although this design can generate argon shield district; but away from argon gas importer to one end air chamber pressure low; argon shield region is very little; protected effect is undesirable; and once liquid metals splashes on argon gas endless tube; easy scaling loss iron sheet and cause gas leakage, more weakens argon shield effect, causes hidden danger to the quality of heavy castings.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, designs a kind of argon seal ring pipe of heavy castings.
The utility model is achieved through the following technical solutions: a kind of heavy castings argon seal ring tubular construction, comprise endless tube body and tunger tube connector, described endless tube body comprises convex core body, water inlet, delivery port, slit cavity air chamber and air-vent.
Further, above-described heavy castings argon seal ring pipe, the air-vent of convex core body outer wall is cancelled, and is provided with equally distributed air-vent on convex core body end face.
Further, above-described heavy castings argon seal ring pipe, uses aluminum-carbon refractory material to replace iron sheet to make convex core body.
The beneficial effects of the utility model are embodied in: heavy castings argon seal ring pipe can strengthen the slit cavity air chamber pressure in water inlet direction, form better argon envelope effect, aluminum-carbon refractory material is used to substitute iron sheet, the liquid metal scaling loss iron sheet solving splashing causes the problem of gas leakage, and then the more stable effect that ensure that argon gas-sealed, be of value to the internal soundness improving heavy castings.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
The utility model discloses a kind of heavy castings argon seal ring pipe, as shown in Figure 3, comprises endless tube body and tunger tube connector (2).Wherein, endless tube body comprises convex core body (1), water inlet (3), delivery port (4), slit cavity air chamber (6) and air-vent (5).Slit cavity air chamber (6) and air-vent (5) are arranged on convex core body (1).Water inlet (3) is identical with delivery port (4) diameter, coaxially arranges with described convex core body.During use, argon gas enters slit cavity air chamber (6) by tunger tube connector (2), then forms argon shield district through air-vent (5) at convex core body (1) endoporus and water inlet (3) direction.Liquid metal is noted into taking up tundish from delivery port (4) from water inlet (3) through argon shield district.
The utility model compared with prior art has the following advantages: 1) eliminate the air-vent to core body outer wall direction, the air pressure in slit cavity air chamber (6) is increased, forms more effective argon shield district to whole endoporus.As shown in Figure 2; most of argon seal ring pipe tops of prior art are closed, can not form argon shield district at top, and as shown in Figure 4; the utility model heavy castings argon seal ring pipe top is provided with air-vent (5), also can form protective atmosphere in water inlet (3) direction.3) the utility model heavy castings convex core body (1) of argon seal ring pipe uses Al_2O_3-C based refractory material to make, and by the liquid metal scaling loss of splashing, can not substantially increase the stability of argon shield effect in use procedure.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of being formed, all drop within the claimed scope of the utility model.
Claims (2)
1. a heavy castings argon seal ring pipe, it is characterized in that: this argon seal ring pipe comprises endless tube body and tunger tube connector (2), described endless tube body comprises convex core body (1), slit cavity air chamber (6), water inlet (3), delivery port (4) and air-vent (5), the air-vent (5) of described convex core body (1) outer wall is cancelled, and arranges equally distributed air-vent (5) at end face.
2. heavy castings argon seal ring pipe according to claim 1, is characterized in that: the material of described convex core body (1) uses aluminum-carbon refractory material to replace iron sheet.
