Abstract

The utility model belongs to the technical field of cast casting and discloses a casting in-gate brick tube for a complex thin-wall cast. The casting in-gate brick tube of the complex thin-wall cast comprises a casting in-gate brick tube body with a portion for jointing the cast. One end of the casting in-gate brick tube body is provided with a circular nozzle, and the other end of the casting in-gate brick tube body is provided with an oval nozzle. The diameter of the circular nozzle of the casting in-gate brick tube body is larger than the minor axis of the oval nozzle and smaller than the major axis of the oval nozzle. The casting in-gate brick tube body between the circular nozzle and the oval nozzle is formed in a streamline shape. Requirements for developing stainless acid-resistant steel ZG0Cr18Ni9 are met, satisfying effect can be obtained from the casting process for complex thin-wall casts such as cases, cracking problem caused by existing in-gate of casts is solved, and design requirements for open pouring gates in the steel casting technology can be met.

Description

A kind of thin-wall complicated foundry goods is with casting ingate brick pipe

[technical field]

The utility model relates to the cast casting technical field, relates in particular to a kind of thin-wall complicated foundry goods with casting ingate brick pipe.

[background technology]At present; When producing stainless acid resistant steel ZG0Cr18Ni9; Foundry goods makes the crack problem that causes because of cast gate easily, and this section brick pipe is applied to ingate and foundry goods junction, washed away continuously by 1600 ℃ of high-temperature molten steels; Make the part material very easily get into foundry goods, bring very big hidden danger to casting quality.

[summary of the invention]

In order to overcome the deficiency in the background technology, the utility model provides a kind of thin-wall complicated foundry goods with casting ingate brick pipe and method, is applicable to the running gate system of stainless steel and thin-walled steel-casting, can satisfy the open running channel designing requirement of cast steel technology.Overcome the easy defective that gets into foundry goods of refractory brick tube material before, guaranteed the steel-casting quality.

In order to realize the foregoing invention purpose, the scheme that the utility model adopted is:

A kind of thin-wall complicated foundry goods is with casting ingate brick pipe; Has ingate brick tube body with the foundry goods junction; Ingate brick tube body one end is provided with the circular mouth of pipe; The ingate brick tube body other end is provided with the oblate mouth of pipe, and the nozzle diameter of the circle of ingate brick tube body is greater than the short spacing of the oblate mouth of pipe, and the nozzle diameter of the circle of ingate brick tube body is less than the long spacing of the oblate mouth of pipe; Be air foil between the mouth of pipe of the circle of ingate brick tube body and the oblate mouth of pipe.

Because adopt aforesaid technical scheme, the present invention has following superiority:

A kind of thin-wall complicated foundry goods is with casting ingate brick pipe; Can satisfy the needs of the stainless acid resistant steel ZG0Cr18Ni9 that develops new product; My company designs a kind of novel cast steel that comes into operation and uses the ingate refractory brick tube; It obtains gratifying effect in the casting cycle of the thin-wall complicated foundry goods of casing class, gram has been answered foundry goods and made the crack problem that causes because of cast gate, and satisfies the open running channel designing requirement of cast steel technology.

[specific embodiment]

As shown in Figure 1; A kind of thin-wall complicated foundry goods is with casting ingate brick pipe; Have the ingate brick tube body 1 that is connected with the foundry goods junction, ingate brick tube body 1 one ends are provided with the circular mouth of pipe, and ingate brick tube body 1 other end is provided with the oblate mouth of pipe; The nozzle diameter of the circle of ingate brick tube body is greater than the short spacing of the oblate mouth of pipe, and the nozzle diameter of the circle of ingate brick tube body is less than the long spacing of the oblate mouth of pipe; Be air foil between the mouth of pipe of the circle of ingate brick tube body and the oblate mouth of pipe.

A kind of thin-wall complicated foundry goods is with casting ingate brick pipe making method, and its step is following:

1, adopts high-quality refractory material to manufacture ingate brick pipe, be used for the running gate system of stainless steel and thin-walled steel-casting, prevent that the refractory brick tube material from getting into foundry goods, improves the steel-casting quality;

2, ingate brick pipe adopts air foil; The oblate mouth of pipe engages with foundry goods, meets the dynamics rule that viscous fluid flows, and the high-temperature molten steel that viscous fluid is flowed gets into foundry goods; Avoid producing the vortex turbulent flow, the gas of avoiding producing gets into the quality that foundry goods improves foundry goods.

Claims

1. a thin-wall complicated foundry goods is with casting ingate brick pipe; It is characterized in that: have ingate brick tube body with the foundry goods junction; Ingate brick tube body one end is provided with the circular mouth of pipe; The ingate brick tube body other end is provided with the oblate mouth of pipe, and the nozzle diameter of the circle of ingate brick tube body is greater than the short spacing of the oblate mouth of pipe, and the nozzle diameter of the circle of ingate brick tube body is less than the long spacing of the oblate mouth of pipe; Be air foil between the mouth of pipe of the circle of ingate brick tube body and the oblate mouth of pipe.
