Description

Graphite brick for molten iron pouring

Technical Field

The utility model belongs to the technical field of the molten iron pouring technique and specifically relates to a graphite brick for molten iron pouring.

Background

At present, the most involved high-temperature molten iron in the casting industry needs to flow into a model through a pouring channel, the pouring channel is an essential part in the casting process, and in the centrifugal casting process, a graphite brick is a part of the pouring channel; the temperature of molten iron is as high as 1400 ℃, any appliance can be washed in the flowing process, the graphite brick is in a shape of a segment of an inferior arc, the radian has a buffering effect, the flowing direction of the molten iron is changed, the molten iron flowing longitudinally is changed into flowing transversely, high-temperature molten iron flows out of the fan-shaped ladle, passes through the graphite brick and flows into the pipe die through the runner, and small-particle alloy materials need to be continuously added in the whole process, and the molten iron needs to flow stably and rapidly for casting and molding. In the process that molten iron flows from the inside of the fan-shaped ladle, the molten iron is splashed under the influence of the flatness of a ladle opening of the fan-shaped ladle and the ladle turning speed, one part of the molten iron is stuck to the top of a graphite brick and does not flow into the graphite brick, residual iron splashed to the top of the graphite brick needs to be cleaned, otherwise, the angle of the fan-shaped ladle during ladle turning can be influenced, the molten iron in the fan-shaped ladle cannot be emptied, and the molten iron is equal to the condition that the part of the molten iron does not flow into a pipe mould, so that defective products such as insufficient pipe weight and the like are caused, and waste is seriously judged; some molten iron glues in graphite brick both sides in addition, forms the sediment iron, prevents to fall into in the molten iron, needs timely clearance, and at the clearance in-process, tear graphite brick atress easily apart, in case there is the gap between the brick, the gap can be bored into to the molten iron, and the expend with heat and contract with cold of sediment iron leads to the gap grow, leads to the unable use of graphite brick. Once the graphite brick cannot be used, a new graphite brick needs to be replaced immediately, and refractory materials are filled around the graphite brick, so that the production cost is increased.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a graphite brick for molten iron pouring can removable mode maintain graphite commentaries on classics, has reduced manufacturing cost.

The utility model adopts the technical proposal that:

the utility model provides a graphite brick for molten iron pouring, its molten iron import is greater than the size of molten iron export, and its inside groove bottom plate is slide formula bottom plate, includes: a plurality of U-shaped groove bricks are spliced and fixed, and the inner surfaces of the U-shaped groove bricks are in smooth transition.

The utility model discloses technical scheme's further improvement lies in: the U-shaped groove bricks are fixed together through a high-temperature resistant adhesive.

The utility model discloses technical scheme's further improvement lies in: and the plurality of U-shaped groove bricks are fixed together through U-shaped clamping pieces.

The utility model discloses technical scheme's further improvement lies in: the U-shaped groove bricks are fixed together through a high-temperature-resistant adhesive and a U-shaped clamping piece.

Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:

the utility model discloses simple structure is convenient for make and maintain, has increased output, has reduced manufacturing cost.

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts;

FIG. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a schematic right-view structural diagram of the present invention;

FIG. 3 is a schematic view of the U-shaped clip of the present invention;

wherein, 1, graphite brick, 2, import, 3, export, 4, U type joint spare, 5, U type groove brick.

Detailed Description

To further illustrate the various embodiments, the present invention provides the accompanying drawings, which are part of the disclosure and which are primarily intended to illustrate embodiments and, together with the description, serve to explain the principles of operation of the embodiments, and, by reference to these drawings, those of ordinary skill in the art will understand the principles of the invention and its advantages, with reference to the drawings and figures, in which elements are not drawn to scale and like elements are generally designated by like reference numerals.

As shown in fig. 1, the present application proposes a graphite brick 1 for molten iron casting, wherein a molten iron inlet 2 of the graphite brick 1 is larger than a molten iron outlet 3, and a bottom plate of the graphite brick 1 is generally of a slide type, and comprises: a plurality of U type groove bricks 5 splice fixedly, and the internal surface smooth transition makes the molten iron flow out smoothly.

Specifically, which U-shaped groove brick 5 in molten iron is called an inlet graphite brick, which U-shaped groove brick 5 in molten iron out is called an outlet graphite brick, and the size of the inlet graphite brick is larger than that of the outlet graphite brick, so that molten iron in the initial ladle turning stage completely flows into the graphite brick 1, the molten iron is prevented from being adhered to the top of the graphite brick 1, the molten iron is ensured to completely flow into a casting, and meanwhile, the cleaning strength of workers is reduced; through the inclined plane of 1 bottom surfaces of graphite brick, make the molten iron that flows in 1 both sides of graphite brick assemble towards graphite brick 1 center, reduce the area of contact of molten iron and brick, can alleviate the washing away of molten iron to the brick, can reduce the iron that glues of graphite brick 1 again.

Furthermore, a plurality of U-shaped groove bricks 5 can be fixed together through a high-temperature-resistant adhesive, the temperature of molten iron is about one thousand, five and hundred degrees, the existing high-temperature-resistant adhesive can resist about two thousand of temperature, the use can be met, the connection mode can be adopted according to the field condition, for example, enough space is available on the field, and a support can be installed to fix the graphite brick 1. Certainly, a U-shaped clamping piece 4 can also be adopted, as shown in fig. 3, a fixing blind hole is arranged at the connecting surface of the U-shaped channel brick 5, and the blind hole is matched with two fixing legs of the U-shaped clamping piece 4; obviously, the graphite bricks can be connected in a bonding and clamping matching mode, the mode is firmer, no gap exists between the graphite bricks 1, the graphite bricks are still a whole, so that slag iron is easy to clean, and the graphite bricks can be continuously used.

Above-mentioned connected mode, when graphite brick 1 goes wrong, only need to change graphite brick 1 wherein certain damaged U type groove brick 5 can, need not scrap whole graphite brick 1, not only prolonged graphite brick 1's life-span, reduced the workman and torn the frequency of beating graphite brick 1 open, reduced refractory material's use, alleviateed workman's intensity of labour, reduced and traded graphite brick 1 influence time, increased output, reduced manufacturing cost.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
