Abstract
The utility model relates to an auxiliary tool in casting production, in particular to an insulating sleeve used for casting, which comprises an outer sleeve, wherein a thermal insulation layer made of nonwettable micropore fire-proof materials is arranged inside the outer sleeve; the thermal conductivity of the nonwettable fire-proof thermal insulation layer ranges from 0.15 to 0.3X10-3W/(m.c); and the compression strength of the outer sleeve is 0.3Mpa. The insulating sleeve achieves the purpose of heat-insulating molten metal mainly through nonwettable fire-proof heat insulating materials, auxiliary heating facilities do not need to be additionally arranged outside the insulating sleeve, and the thermal insulation effect is good. Compared with the present insulating sleeve the insulating sleeve for casting has the advantages of simple structure, convenient manufacture and use, low manufacturing cost, safety and reliability, good thermal insulation effect, good air tightness and high-temperature resistance, and therefore the quality and the performance of casts and strong practicability are ensured.
Description
Technical field:
The utility model relates to a kind of aid in the casting production, is specifically related to a kind of casting muff.
Background technology:
In the casting production process, molten metal from casting machine to the flow process of mould, be attended by cooling, processes such as gas leakage and crystallization, have a strong impact on the quality and the performance of cast parts, air tight in flow process in order to guarantee molten metal, do not lower the temperature, in casting cycle, increased muff, it is a necessary aid during the low pressure casting is produced, its main purpose is in order to guarantee that molten metal flows to mould smoothly by muff in the casting cycle, and it is air tight in the flow process, do not lower the temperature, this just requires thermos to be equipped with certain intensity, high temperature resistant, good heat insulating, air-tightness reaches characteristics such as easy to operate well, traditional muff mainly heats the purpose that reaches insulation by electrification outside muff or combustion gas to muff, but these muff poor effect, problems such as cooling gas leakage have still appearred aborning, influenced casting quality and performance, and there is complex structure in these muffs, production cost height and unsafe factor.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of casting muff, it mainly reaches the insulation purpose by not soaking into flame-proof thermal insulation material, therefore simple with original muff structure compared, make easy to use, the insulation airtight effect better, production cost is low.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of casting muff, it comprises overcoat 1, wherein: be provided with the heat-insulation layer 2 that does not soak into fire resistant heat preserving in the described overcoat 1.
Further, described heat-insulation layer 2 does not soak into refractory material for micropore.
The beneficial effects of the utility model are:
The utility model mainly reaches purpose to molten metal thermal insulation by not soaking into flame-proof thermal insulation material, need not increase auxiliary heating facility outside muff, its heat insulation effect is better on the contrary, therefore compares with existing muff, the utility model is simple in structure, make easy to usely, the cost cost is low, and is safe and reliable, high insulating effect, air-tightness is good and high temperature resistant, and then guarantees the quality and the performance of foundry goods, and is practical.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, overcoat 1 coated inner wall has the heat-insulation layer 2 that does not soak into fire resistant heat preserving, and heat-insulation layer 2 adopts micropore not soak into refractory material and makes, and its thermal conductivity is 0.2 * 10
-3W/ (m.c), overcoat 1 withstand voltage 0.3Mpa.
During use, with the liquid outlet of end connection casting machine of the present utility model, the inlet that the other end connects mould gets final product, molten metal in the casting machine flows out from liquid outlet, through the utility model, enters mould, because heat-insulation layer 2 adopts micropore not soak into refractory material and makes, and its thermal conductivity is 0.2 * 10
-3W/ (m.c), so heat-insulation layer 2 can guarantee its air-tightness again to molten metal thermal insulation, but also can not burnt out by the temperature of molten metal, because overcoat 1 withstand voltage 0.3Mpa, so overcoat 1 has guaranteed withstand voltage properties of the present utility model.
Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art, as long as do not exceed the thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
Claims (2)
1. casting muff, it comprises overcoat (1), it is characterized in that: be provided with the heat-insulation layer (2) that does not soak into fire resistant heat preserving in the described overcoat (1).
