Abstract
The utility model discloses a cast iron mould which is long in service life and not easy to crack. The cast iron mould comprises a casing with a cavity. The casing comprises an inner side face, an outer side face, an inner bottom face and an outer bottom face. Protrusions are arranged on the inner bottom face, an internal arc transition area is arranged between the inner side face and the inner bottom face, and an external arc transition area is arranged between the outer side face and the outer bottom face. At least two rebars are buried at the bottom of the casing along the longitudinal direction of the casing and extend to the other end of the casing from one end of the casing along the longitudinal direction of the casing. The radius of the internal arc transition area is in a range of 40mm to 45mm, and the radius of the external arc transition area ranges from 80mm to 85mm. Distances between the top ends of the protrusions and the inner bottom face of the casing are in a range of 15mm to 20mm.
Description
Technical field
The utility model relates to a kind of pig mold, relates in particular to a kind of pig mold for the production of ferronickel.
Background technology
Existing pig mold for the production of ferronickel generally comprises one with the housing of inner chamber, housing comprises medial surface, lateral surface, inner bottom surface and outer bottom, be provided with projection on the inner bottom surface, being inner circular arc transition region between described medial surface and the inner bottom surface, is outside circular arc transition region between described lateral surface and the outer bottom.Existing this housing cause the material scaling loss serious, and enclosure interior stress concentration phenomenon is serious because its design size is unreasonable, often causes the housing cracking.So that the service life of pig mold is shorter.
In order to improve service life, prior art has been carried out a lot of trials, and for example Chinese patent 200920091522.1 discloses a kind of anti-crack energy-saving cast iron mold, is provided with the isolation strip at the die body inner surface, and the isolation strip is concave.Chinese patent 200620116079.5 discloses a kind of long life cast iron mould for another example, and this pig mold bottom interior surface is identical with the basal surface geometric profile, pig mold bottom wall thickness consistent size.Although these trials can improve the service life of pig mold, the effect that improves is not clearly, and still there is problem of Cracking in subject matter.When especially producing ferronickel, because the housing temperature difference is very large, problem of Cracking is even more serious.
The utility model content
The technical problem that the utility model solves provides long pig mold not easy to crack in a kind of service life.
The technical scheme that its technical problem that solves the utility model adopts is: pig mold, comprise the housing with inner chamber, housing comprises medial surface, lateral surface, inner bottom surface and outer bottom, be provided with projection on the inner bottom surface, it is inner circular arc transition region between described medial surface and the inner bottom surface, be outside circular arc transition region between described lateral surface and the outer bottom, the bottom of housing vertically is embedded with at least two reinforcing bars along housing, and described reinforcing bar is extended longitudinally to the other end of housing along housing by an end of housing.
Further be: the radius of described inner circular arc transition region is 40～45mm, and the radius of described outside circular arc transition region is 80～85mm.
Further be: the top of described projection is 15～20mm apart from the distance of the inner bottom surface of housing.
The beneficial effects of the utility model are: carry out mechanical type by reinforcing bar and be connected and fixed, can offset a part of local stress, force again simultaneously to fix, slow down the development that can stop again crackle when crackle produces, reach and improve the pig mold purpose in service life.Appropriate design by to inner arc transition district and outside circular arc transition region has significantly reduced local stress, has effectively avoided the generation of crackle.By the size of appropriate design projection, can effectively reduce the scaling loss of material.
Description of drawings
Fig. 1 is the top view of pig mold of the present utility model;
Fig. 2 is the cutaway view of the A-A direction of Fig. 1;
Fig. 3 is the cutaway view of the B-B direction of Fig. 1;
Be labeled as among the figure: housing 1, inner bottom surface 21, medial surface 22, inner circular arc transition region 23, outer bottom 31, lateral surface 32, outside circular arc transition region 33, reinforcing bar 4, projection 5, bottom 6.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
As shown in Figure 1 to Figure 3, pig mold of the present utility model, comprise the housing 1 with inner chamber, housing 1 comprises medial surface 22, lateral surface 32, inner bottom surface 21 and outer bottom 31, be provided with projection 5 on the inner bottom surface 21, it is inner circular arc transition region 23 between described medial surface 22 and the inner bottom surface 21, it is outside circular arc transition region 33 between described lateral surface 32 and the outer bottom 31, bottom 6 at housing vertically is embedded with at least two reinforcing bars 4 along housing, and described reinforcing bar 4 is extended longitudinally to the other end of housing 1 along housing by an end of housing 1.Because housing bottom is main cracking district, by burying reinforcing bar 4 underground, so that housing bottom is strengthened, slow down the development that can stop again crackle when crackle produces, but and then the service life of Effective Raise pig mold.
Because inside circular arc transition region and outside circular arc transition region on the pig mold all are region of stress concentrations, these zones are prone to crackle, in order further to improve the service life of pig mold, need to carry out appropriate design to these zones.As shown in Figures 2 and 3, the radius of described inner circular arc transition region 23 is 40～45mm, and the radius of described outside circular arc transition region 33 is 80～85mm.Found through experiments, adopt said structure, the effectively appearance of Crack prevention.Especially when producing ferronickel, compared with prior art, the effectively appearance of Crack prevention.
Prove that by experiment the height of projection 5 plays decisive role to the scaling loss of material, therefore the height of projection 5 need to be reasonable in design, should reduce the scaling loss of material, and the height of again assurance projection 5 satisfies instructions for use.As shown in Figure 2, described protruding 5 top is 15～20mm apart from the distance of the inner bottom surface 21 of housing 1.
