Abstract
The utility model discloses a fence type smelting crucible which comprises a crucible body and a fence in a round pipe shape. The lower end of the fence stretches into an end opening of the crucible body in a matched mode, and a plurality of cross rod supporting feet are welded to the side wall of the lower portion of the fence. The cross rod supporting feet are supported on the end opening of the crucible body, and annular supports are fixedly arranged at the ends of the cross rod supporting feet through bolts. A sprue is formed in the end opening of the crucible body, an opening is formed in the position, close to the sprue, of the lower end of the fence, and gaps corresponding to the sprue are formed in the annular supports. The number of adopted crucible materials is reduced, the loading, slag removing and other operations in the smelting process are facilitated through the arranged crucible structure, high practicality is achieved, and the fence type smelting crucible is worthy of being popularized.
Description
Technical field
The utility model relates to a kind of fence type melting kettle.
Background technology
At present, sintered NdFeB temperature when melting reaches 1450-1500 ℃, therefore, require crucible can be high temperature resistant, long-life, low cost, conventionally adopt alumina crucible.During shove charge, raw material are slightly higher than mouth of pot, and after raw material fusing, molten steel is positioned at crucible bottom, thus tend to cause crucible bottom more easily to occur loss, cracking, disrepair phenomenon, thus cause whole crucible to scrap.Crucible of the prior art, is cylindrical crucible structure, will cause integral body to scrap, thereby increased production cost once crucible bottom is damaged.The crucible of the every stove of 600kg of take is example, and its degree of depth is about 800mm, is unfavorable for mending crucible operation.Because crucible height is limited, when filling with substance raw material can be higher than mouth of pot again, and the raw material at mouth of pot place constantly melt, decline in fusion process, may be crowded together and occur arch formation, the major accident such as cause that device damage, raw material are scrapped when serious.
Chinese invention patent (201110271771.0) " a kind of composite crucible for growth of sapphire crystals " discloses a kind of composite crucible, crucible main body and lengthening crucible tube, consists of, and crucible main body and lengthening crucible tube are socketed by location mating surface.The wall thickness that lengthens crucible tube in this invention is the same, heavier with crucible main body, is not easy dismounting, only when crucible main body is damaged, just pulls down.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of fence type melting kettle.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of fence type melting kettle, the fence that comprises crucible body and circular tube shaped, the lower end coupling of described fence extend in the port of described crucible body, and is also welded with many cross bar legs on this fence lower sides; Described cross bar leg is supported on the port of crucible body, and the end of cross bar leg is mounted by means of bolts on an annular support; On the port of described crucible body, be provided with sprue gate, the lower end of described fence is being provided with opening near place, sprue gate, and is also provided with the breach corresponding to described sprue gate on described annular support.
Further, described crucible body is cylindric, and the internal depth of crucible body is 650mm, and wall thickness is 20～35mm.
Further, the employing stainless steel of described fence is made, and this fence height is 300mm, and wall thickness is 1.0mm.
Compared with prior art, the utility model has the advantages that: this crucible material consumption is few, is about 85% of conventional crucible, can save crucible manufacturing cost.The crucible degree of depth only has 75～85% of conventional crucible, operator can be deep into easily crucible bottom by hand and mend crucible operation, the good repairing in time of crucible extended its service life, is about 1.5～2 times of conventional pot life, reduced the use cost of crucible.In fusion process, it is inner that molten steel is positioned at stainless crucible, the bottom of fence and liquid steel level are at a distance of 100～200mm, the temperature of fence is far below the temperature of molten steel, again because fence has corrosion-resistant, resistant to elevated temperatures feature, guaranteed fence in fusion process still in solid-state, there is long-lived feature.In addition, the total height that crucible adds upper railings is greater than the height of conventional crucible, easily charging, and device damage, the raw material that can avoid to the utmost arch formation to cause in fusion process such as scrap at the major accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the fence type melting kettle the utility model proposes, comprises the fence 2 of crucible body 1 and circular tube shaped, and the lower end coupling of fence extend in 1 port of crucible body, and is also welded with many cross bar legs 3 on these fence 2 lower sides; Cross bar leg 3 is supported on the port of crucible body 1, and the end of cross bar leg 3 is mounted by means of bolts on an annular support 4; On the port of crucible body 1, be provided with sprue gate 11, the lower end of fence 2 is being provided with opening 21 near 11 places, sprue gate, and is also provided with the breach corresponding to sprue gate 11 on described annular support.Crucible body 1 is cylindric, and the internal depth of crucible body is 650mm, and wall thickness is 25mm.The employing stainless steel of fence 2 is made, and this fence height is 300mm, and wall thickness is 1.0mm.Fence 2 external diameters are more smaller than crucible body 1 internal diameter, can put into crucible body, and can in crucible body, take out easily.
In actual production, after melting finishes, first take off fence 2, removing slag is also repaired crucible body 1, is loaded on a part of raw material, then fence 2 is fixed on annular support 4, finally remaining raw material is packed in fence 2.Adopt after this structure, be convenient to mend crucible operation, extended the service life of crucible body 1, thereby saved the use cost of crucible body, the height of fence 2 is enough, facilitated charging operation, device damage, the raw material of also having avoided to the utmost arch formation to cause in fusion process such as scrap at the major accident.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
