Abstract
The invention discloses a fence type smelting crucible. The crucible comprises a crucible body and a tubular fence, wherein the lower end of the fence protrudes into a port of the crucible body, the lower side wall of the fence is further welded with a plurality of cross bar supports; the cross bar supports are supported on the port of the crucible body, and the tips of the cross bar supports are fixedly provided with an annular support through a bolt; a pouring opening is formed above the port of the crucible body, the lower end of the fence is provided with an opening nearby the pouring opening, and a gap corresponding to the pouring opening is further formed in the annular support. According to the fence type smelting crucible provided by the invention, the fence structure is convenient to charge, clear up slag and the like in the process of smelting, and is strong in practicality and is worthy of popularizing.
Description
Technical field
The present invention relates to a kind of fence type melting kettle.
Background technology
At present, sintered NdFeB temperature when melting reaches 1450-1500 DEG C, therefore, require crucible can high temperature resistant, long-life, low cost, usually 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, so often cause crucible bottom more easily to occur loss, cracking, disrepair phenomenon, thus causes whole crucible to scrap.Crucible of the prior art is cylindrical crucible structure, entirety will be caused to scrap, thus increase production cost once crucible bottom is damaged.For the crucible of the every stove of 600kg, its degree of depth is about 800mm, is unfavorable for mending crucible operation.Again due to crucible limited height, when filling with substance raw material higher than mouth of pot, constantly can melt at the raw material at mouth of pot place, decline in fusion process, may be crowded together and occur arch formation, the major accident such as cause device damage time serious, raw material are scrapped.
Chinese invention patent (201110271771.0) " a kind of composite crucible for growth of sapphire crystals " discloses a kind of composite crucible, is made up of Crucible body and lengthening crucible tube, and Crucible body and lengthening crucible tube are connect by location fit surface cover.The wall thickness of crucible tube and the same of Crucible body is lengthened in this invention, heavier, be not easy dismounting, only just pull down when Crucible body is damaged.
Summary of the invention
The present invention, in order to solve the above-mentioned deficiency of prior art, proposes a kind of fence type melting kettle.
In order to solve the problems of the technologies described above, the present invention is by the following technical solutions: a kind of fence type melting kettle, comprise the fence of crucible body and circular tube shaped, the lower end coupling of described fence extend in the port of described crucible body, and this fence lower sides is also welded with many cross bar legs; 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; The port of described crucible body is provided with sprue gate, and the lower end of described fence is being provided with opening near sprue gate place, and described annular support is also provided with the breach corresponding to described sprue gate.
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, advantage of the present invention is: 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, hand can be deep into crucible bottom and carry out the operation of benefit crucible by operator easily, in time good repairing of crucible extends its service life, is about 1.5 ~ 2 times of conventional crucible service life, reduces 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, ensure that fence is still in fusion process 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 feeds, and the device damage that arch formation can be avoided in fusion process to the utmost to cause, raw material such as to scrap at the major accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, invention is described in detail.
As shown in Figure 1, the fence type melting kettle that the present invention 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 this fence 2 lower sides is also welded with many cross bar legs 3; 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; The port of crucible body 1 is provided with sprue gate 11, the lower end of fence 2 is being provided with opening 21 near sprue gate 11 place, and described annular support is also provided with the breach corresponding to sprue gate 11.Crucible body 1 is in 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 diameter is more smaller than crucible body 1 internal diameter, can put into crucible body, and can take out in crucible body easily.
In actual production, after melting terminates, first take off fence 2, removing slag also repairs crucible body 1, is loaded on a part of raw material, is then fixed on annular support 4 by fence 2, is finally loaded in fence 2 by remaining raw material.After adopting this structure, be convenient to mend crucible operation, extend the service life of crucible body 1, thus saved the use cost of crucible body, the height of fence 2 is enough, facilitate charging operation, in fusion process, also avoid device damage that arch formation may cause to the utmost, the major accident such as raw material are scrapped.
Above-described embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, patent of the present invention and protection domain should be as the criterion with appended claims.
