Abstract
A long-life iron-casting mould belonging to metallurgic mechanic technical field is provided, which is used for solving the local internal stress produced by iron-casting mould due to uneven heating. The inner surface of the iron-casting base after being improved is same with the geometric outline of bottom surface and is consistent with the dimension of the iron-casting mould base. The utility model made improvement on preventing the damage to the iron-casting mould due to high temperature and the spreading of molten iron on the roll wheel and gluing the roll wheel, which is characterized in that: 1. it improves the iron-casting mould dimension and keeps the wall thickness of the base consistent, thus can effectively eliminate or reduce the local internal stress and prevent the iron-casting mould from rupturing and enhance three times of the service life of the iron-casting mould. 2. An anti-molten iron spreading plate is provided on the side of the iron-casting mould so as to effectively prevent the molten iron and other sundries from entering into roller wheel turning pairs, ensure the flexible rotation of the roller wheel, and avoid sealing the roller wheel of iron-casting chain and joint of outer gliding bushing due to spattering of the molten iron. The utility model has the advantages of being simple in structure and easy to realize. In addition, after being improved, the utility model is able to prolong the service life of the iron-casting mould and reduce maintenance time and manufacturing cost.
Description
Technical field
The utility model relates to a kind of metallurgical machinery parts, the pig mold that is used to cast and casts iron ingot.
Background technology
Pig mold is to be used for the mould that blast furnace process is cast iron ingot, and is one of critical piece in the metallurgy industry iron-smelter pig machine.The motion that a plurality of pig molds that molten iron is housed are dragged by the chain belt of shuttling movement on the pig machine, the molten iron in the pig mold through the cooling of cooling device, is frozen into ingot iron in motion process.Referring to Fig. 2, the pig mold 7 of common Cast Iron Machine of Cantilever Roller and chain belt 6 are by roller 3 supportings, and roller is by track 5 supportings.The problem that exists is: 1. pig mold bottom size thickness does not wait, and heat conduction is irregular, and causes local internal stress at weak part easily, and pig mold is cracked under the rapid heat cycle effect, thereby influences the service life of pig mold.2. in the molten iron casting cycle, because molten iron collapses and spatters, have the hinged place that some molten iron splash roller 3, outer sliding sleeve 4, make both seam or stuck, roller becomes mutual slip by pure rolling in orbit, has accelerated the wearing and tearing of roller and track, and the chain belt resistance of motion is increased, strengthened the initiatively load of machine, making initiatively, machine is in hard service.
Summary of the invention
The utility model is used to overcome the defective of prior art and provides a kind of and eliminate or reduce local internal stress, prevents the die body cracking, improves the pig mold long-lived pig mold in service life.
The alleged problem of the utility model is that following technical scheme solves:
A kind of long-lived pig mold is arranged between the roller of chain belt of pig machine, and its special feature is: described pig mold 1 bottom interior surface is identical with the basal surface geometric profile, pig mold bottom wall thickness unanimity.
Above-mentioned long-lived pig mold is set up anti-molten iron splash guard 2, and described anti-molten iron splash guard is positioned at pig mold side, chain belt of pig machine roller top, and described anti-molten iron splash guard is an arc.
The utility model improves the problem that collapses spatter at pig mold high temperature deformation damage and molten iron and connect roller, its characteristics are as follows: improve the pig mold physical dimension 1., make its bottom wall thickness consistent size, local internal stress can be effectively eliminated or be reduced in this improvement, avoid because of the irregular pig mold fracture that makes of being heated, about three times of the service life of raising pig mold; 2. set up anti-molten iron splash guard at the pig mold side, prevent that effectively molten iron and other foreign material from entering in the roller rotary pair, guarantee the flexible rotation of roller, avoid spattering because of molten iron collapses, make the roller and the seam of outer sliding sleeve junction of chain belt of pig machine, produce bigger resistance to sliding.The utility model is simple in structure, is easy to realize, can obviously improve pig mold service life after the improvement, reduces maintenance time and production cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of pig mold before improving.
The label of each parts is expressed as follows in the accompanying drawing: 1. pig mold; 2. anti-molten iron splash guard; 3. roller; 4. outer sliding sleeve; 5. track; 6. chain belt; 7. the plain cast iron mould before improving.
The specific embodiment
Referring to Fig. 1, to be the problem that differs, cause easily local internal stress at plain cast iron mould bottom wall thickness dimension improve the geometric profile of pig mold an important improvement of the present utility model, the upper and lower surface, bottom of improving back pig mold 1 has concavo-convex geometry consistent with each other, through this improvement, pig mold bottom wall thickness consistent size can effectively be eliminated or reduce because of the uneven local internal stress that produces of being heated.
Still referring to Fig. 1, another improvement of the present utility model is to set up anti-molten iron splash guard 2, and anti-molten iron splash guard is positioned at pig mold side, chain belt of pig machine roller 3 tops, and described anti-molten iron splash guard is an arc.After the improvement, in the molten iron casting cycle, collapse the molten iron that spatters and can not collapse and splash roller and outer sliding sleeve 4 junctions, avoid causing the junction seam, and increase the frictional resistance between roller and the track 5 because of chain belt of pig machine roller and outer sliding sleeve spatter because of molten iron collapses.
Claims (2)
1. a long-lived pig mold is arranged between the roller of chain belt of pig machine, it is characterized in that: described pig mold (1) bottom interior surface is identical with the basal surface geometric profile, pig mold bottom wall thickness unanimity.
2. long-lived pig mold according to claim 1 is characterized in that: set up anti-molten iron splash guard (2), described anti-molten iron splash guard is positioned at roller (3) top of pig mold side, chain belt of pig machine, and described anti-molten iron splash guard is an arc.
