Abstract
The utility model discloses a kind of tundish of prealloy powder melting, it comprises prefabricated crucible, graphite linings, magnesia layer, iron sheet layer from inside to outside, the prefabricated crucible in innermost layer is connected with graphite linings, between graphite linings and outermost layer iron sheet layer, squeezes into magnesia, plays fixation.The utility model is simple in structure; easy to operate; add graphite linings, utilize the characteristic of graphite, not only play the service life that thermolysis has improved crucible; and; the in the situation that of crucible cracking, there is the protection fixation of graphite linings, avoid molten metal to flow out; safe and reliable, reduction loss, cost-saving.
Description
Technical field
The utility model relates to prealloy powder high melt production equipment, is more specifically a kind of tundish of prealloy powder melting, is applicable to prealloy powder high melt.
Background technology
Tundish is that prealloy powder high melt is produced one of visual plant; in prealloy powder high melt technology; when molten metal injects tundish; severe impact when liner crucible bears the static pressure of high-temperature liquid metal and fluid; and the chilling and shock heating of temperature; traditional tundish with the fixing crucible of magnesia, can not play a very good protection to crucible merely, after a crucible only uses three, four times due to inhomogeneous the breaking of being heated.And molten metal easily flows out when crucible cracking, the molten metal temperature of outflow is very high, as careless manipulation easily damages to staff, also causes waste simultaneously, has increased production cost.And the improvement that the utility model carries out for above-mentioned deficiency just consists of prefabricated crucible, graphite linings, magnesia layer, iron sheet layer from inside to outside.Graphite has good chemical stability, thermal conductivity is good, with the fixing crucible of graphite linings, can be convenient to prefabricated crucible heat radiation, avoids breaking because crucible internal/external heating is inhomogeneous, and brought up to tens times the service life of crucible by three, four times.And the graphite thermal coefficient of expansion is little, the variation of ability rapid heat cycle, can not cause crimp to inner crucible, and in crucible cracking situation, molten metal is also difficult for flowing out, and reduces loss, cost-saving.
Utility model content
The purpose of this utility model is the problems referred to above that are for prior art existence, and a kind of tundish of prealloy powder melting is provided, and has solved in prealloy powder melting technique, when molten metal injects crucible, temperature, up to 1500 ℃, is easy to cause crucible to break, the problem that molten metal flows out.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A tundish for prealloy powder melting, comprises prefabricated crucible, and described prefabricated crucible is wrapped with graphite linings, and graphite linings outer wrap has iron sheet layer, between graphite linings and iron sheet layer, is filled with magnesia layer.
The utility model comprises prefabricated crucible, graphite linings, magnesia layer, the iron sheet layer arranging from inside to outside; the prefabricated crucible in innermost layer is connected with graphite linings; utilize the special nature of graphite; play the fixedly effect of inner crucible of protection; between graphite linings and outermost layer iron sheet layer, fill magnesia layer, play fixation.Four-layer structure is fixing layer by layer, makes innermost layer crucible stable.
The utility model compared with prior art, has the following advantages:
The utility model is simple in structure, handling safety, convenience, and four-layer structure is fixing layer by layer.Graphite linings is not only fixed prefabricated crucible, has also improved the service life of crucible.In addition, the in the situation that of crucible cracking, there is the protection fixation of graphite, avoid molten metal to flow out, reduce loss, cost-saving.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model;
Fig. 2 is cross-sectional view of the present utility model.
Wherein: the prefabricated crucible of 1-, 2-graphite linings, 3-magnesia layer, 4-iron sheet layer.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 and 2, a kind of tundish of prealloy powder melting, comprises prefabricated crucible 1, and described prefabricated crucible 1 is wrapped with graphite linings 2, and graphite linings 2 outer wrap have iron sheet layer 4, between graphite linings 2 and iron sheet layer 4, are filled with magnesia layer 3.As a kind of preferred version, the lateral wall of the prefabricated crucible 1 of graphite linings 2 parcel, magnesia layer 3 wraps the whole prefabricated crucible 1 that is provided with graphite linings 2, and iron sheet layer 4 comprises whole magnesia layer 3, prefabricated crucible 1 bottom offers liquid outlet, and magnesia layer 3 and iron sheet layer 4 are corresponding to the part perforate of liquid outlet.
The utility model in use; the molten metal of crossing through high melt injects prefabricated crucible 1; when molten metal injects, temperature is very high; graphite linings 2 plays the effect of the fixing prefabricated crucible 1 of protection; graphite has good chemical stability, thermal conductivity is good; with the fixing prefabricated crucible 1 of graphite linings 2; can be convenient to prefabricated crucible 1 heat radiation; avoid because of inhomogeneous the breaking of prefabricated crucible 1 internal/external heating; improved the service life of prefabricated crucible 1; while not adding graphite linings 2, a prefabricated crucible 1 can only use three to four times, adds after graphite linings 2, and a prefabricated crucible 1 can use tens times.In addition, the graphite thermal coefficient of expansion is little, and the variation of ability rapid heat cycle can not cause crimp to the prefabricated crucible 1 of internal layer, and in prefabricated crucible 1 cracking situation, molten metal is also difficult for flowing out, and reduces loss, cost-saving.Magnesia layer 3 is graphite linings 2 fixedly, and outermost layer iron sheet layer 4 is magnesia layer 3 fixedly, also plays contraction simultaneously.The utility model adopts four-layer structure fixing, safe ready layer by layer.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
