Abstract
The utility model relates to a compound crucible which comprises a crucible body, wherein the outer surface of the crucible body is provided with bulges, a magnesia powder layer is arranged at recessions on the outer surface of the crucible body which is made of cast iron, the bulges are arranged regularly, and the outer surface of the crucible is provided wave-shaped bulges or strip-shaped bulges. The magnesia powder is coated on the outer surface of the crucible body, so that the outer surface of the cast iron of the crucible is not contacted with air so as not to be oxidized, therefore, the crucible has long service life; the crucible body is provided with the regular bulges, so that the heating area is increased and the heat conducting performance is good; the magnesia powder is arranged at the recessions, so that the crucible has the characteristic that the magnesia is not easy to fall off; and the magnesia powder on the crucible is a high temperature insulation heat conduction material, high temperature heating wires are arranged in the magnesia powder layer, so that the heating speed is fast, the energy consumption is low and the crucible is convenient to use.
Description
Technical field
The utility model relates to the crucible field, especially relates to a kind of composite crucible.
Background technology
The crucibles such as existing molten aluminium, molten zinc mainly contain three kinds: 1, graphite or silicon carbide crucible, the shortcoming of this type of crucible be intensity difference easily broken, heat conductivility is general; 2, cast-iron pot, the fast intensity of this crucible heat conduction is high, but the easy oxidation in outer surface direct contact heat source is short service life, is only the 1-2 month.Now commonly use the equipment that melts the low-melting-point metals such as aluminium and be mainly crucible type electric furnace, coke-fired furnace or gas furnace, have the slow shortcoming of heating, the working environment of natural gas and coke-fired furnace is also poor.
The utility model content
The purpose of this utility model one provides a kind of long service life, high strength, heat to conduct fast composite crucible.
The purpose of this utility model two provides the composite crucible that a kind of firing rate is fast, energy loss is little.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of composite crucible comprises the crucible body, has projection at the outer surface of described crucible body, and the recess of described outer surface is provided with the magnesia bisque.
As preferred technical scheme, the material of described crucible body is cast iron.
As preferred technical scheme, described projection is regularly arranged.
As preferred technical scheme, the outer surface of described crucible body is wavy bulge, and described magnesia powder is arranged on described corrugated recess, be beneficial to fixedly magnesia powder, difficult drop-off, and waveform has increased heating surface area, heat conductivility extends pot life near cast iron.
As preferred technical scheme, also comprise heating wire, described heating wire is fixed in described magnesia bisque, described heating wire is that common this kind of high-temperature electric heated filament auxiliary heating mode or active mode of heating makes the speed of heating fast, energy loss is little, add a power supply and get final product melting, easy to use.
The utility model compared with prior art has following beneficial effect:
(1) be coated with magnesia powder on the outer surface of crucible body, make the cast iron outer surface of crucible not have the ingress of air can oxidation, long service life;
(2) be provided with uniform projection on the crucible body, increased heating surface area, good heat conductivity; Magnesia powder is arranged on recess, has the characteristics of magnesia powder difficult drop-off;
(3) the crucible body is that cast iron makes crucible intensity high difficult broken;
(4) be provided with the high-temperature electric heated filament in the magnesia bisque of crucible, the firing rate that is is fast, and energy loss is little, and is easy to use.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The front view of a kind of composite crucible of Fig. 1 the utility model;
The profile of a kind of composite crucible of Fig. 2 the utility model;
Fig. 3 is a kind of compound firm top view of the utility model.
Number in the figure:
1-crucible body, 11-projection, 12-recess, 2-magnesia bisque.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1-3, composite crucible comprises crucible body 1.Wherein the outer surface of crucible body 1 has projection 11, and the recess 12 of outer surface is provided with magnesia bisque 2.The crucible body is the shape of existing common crucible, and namely the section of crucible body 1 is U-shaped.The materials'use cast iron of above-mentioned crucible body 1.The purpose of projection 11 is in order to increase heating surface area, simultaneously magnesia powder to be fixed on recess, be easy to fixedly magnesia powder difficult drop-off, therefore described protruding 11 can arranging for various forms.Choose projection 11 in the present embodiment for regularly arranged, and be corrugated.Certainly the outer surface of crucible body 1 can also be chosen the striated projection, and magnesia powder is arranged on the recess of striated, is beneficial to fixedly magnesia powder.That magnesia powder has is high temperature resistant, insulation, heat conduction, oxidation resistant effect.
In order to make this crucible easy to use, firing rate is fast, and loss is little, and this crucible also can comprise heating wire (not marking in figure).Heating wire is fixed in the magnesia bisque, and heating wire is the market common materials.This kind auxiliary heating mode or active mode of heating make the speed of heating fast, and energy loss is little, adds a power supply and gets final product melting, and is easy to use.
The cast iron outer surface of composite crucible of the present utility model does not have the ingress of air can be not oxidized, long service life, and good heat conductivity, firing rate is fast, and energy loss is little, and intensity is high, and is easy to use.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
