Technical field
The present invention relates to a kind of heater, particularly a kind of fritting formula crucible heating device, belongs to crucible applied technical field.
Background technology
Existing crucible adopts extremely fire-resistant material, and as clay, graphite, china clay, quartz or more infusibilized metallic iron etc. are made, so crucible is usually used in the high-temperature heating treatment process of material.In scientific experiment or suitability for industrialized production, in order to make certain material or height melt boiling point metal molten, boiling, volatilize, first to select fusing point higher than the crucible of this kind of material or metal boiling point, just then can put it in crucible, heat, melt, seethe with excitement, volatilize.Though the fusing point of existing crucible can reach more than 1600 ℃, but the metallics for some higher boiling (boiling temperature reaches more than 2000 ℃), if boiling point is the metal tantalum of 5425 ℃, still cannot meet its demand for heat, if adopt other high-temperature services to heat, device structure is complicated, cost is higher, and common crucible is for a long time in heated condition, life-span is shorter, is unfavorable for large-scale industrial production application.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of fritting formula crucible heating device, can effectively heat higher boiling (boiling temperature reaches more than 2000 ℃) material, meet its demand for heat, device for simultaneous heating is simple in structure, cost is low, has effectively extended the service life of crucible in heating process.
To achieve these goals, a kind of fritting formula crucible heating device that the present invention adopts, comprises water cooling box, heat-insulation layer, crucible layer, and described water cooling box inside is provided with cooling bath, is also filled with heat-insulation layer in water cooling box, is placed with crucible layer on heat-insulation layer.
Further, described crucible layer comprises that quantity is no less than two-layer crucible.
Further, in described crucible layer, the material of adjacent two layers crucible is identical or different.
Further, described cooling bath is comprised of two-layer stainless steel.
Further, described heat-insulation layer is comprised of graphite felt.
Compared with prior art, the invention has the beneficial effects as follows:
(1) fritting formula crucible heating device can meet the heat request that adds of different molten boiling point materials, heating object in crucible layer is divided into boiling section, fusion zone and solidification zone, be that heating object in crucible layer exists obvious thermograde and two physics phase points, be boiling point and fusing point junctional area, to temperature range, be that 2000 ℃ of molten boiling point materials of above height can effectively heat, fusing, boiling, the PROCESS FOR TREATMENT such as volatilization, do not need to use other complex structures, firing equipment that cost is high to complete.
(2) while using fritting formula crucible heating device to heat material, do not need in crucible, to add other materials, crucible does not contact with the liquid phase of heating object, and has lower thermograde region,, with heating object generation physics and chemical reaction, effectively do not avoided the pollution of product.
(3), while using, can by the crucible of the same material of multi-layer phase, multilayer unlike material separately or be used in conjunction with, effectively raise crucible serviceability; When the material of the crucible in the crucible layer using is not identical, outer crucible can effectively reduce the thermal loss of inner crucible, puies forward high-octane utilization rate, improves the efficiency of heating surface.
(4) by passing into cooling water in the cooling bath in water cooling box, to crucible effective temperature-reducing, guarantee that crucible is in its temperature resistant range, and can Yin Gaowen or contact and cause that physics or chemical reaction cause the consumption to crucible with material-to-be-heated liquid phase, the service life of crucible extended.

In figure: 1, water cooling box, 1.1, cooling bath, 2, heat-insulation layer, 3, crucible layer, 4, heating source, 5, boiling section, 6, melting zone, 7, solidification zone.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, a kind of fritting formula crucible heating device, comprises water cooling box 1, heat-insulation layer 2, crucible layer 3, and described water cooling box 1 inside is provided with cooling bath 1.1, is also filled with heat-insulation layer 2 in water cooling box 1, is placed with crucible layer 3 on heat-insulation layer 2.
As a further improvement on the present invention, described crucible layer 3 comprises that quantity is no less than two-layer crucible, and the material of adjacent two layers crucible is identical or different all can effectively improve crucible serviceability; When the material of the crucible in the crucible layer 3 using is not identical, outer crucible can effectively reduce the thermal loss of inner crucible, puies forward high-octane utilization rate, improves the efficiency of heating surface.
As a further improvement on the present invention, cooling bath 1.1 is comprised of two-layer stainless steel, and obturation effect is good, effectively to the outer crucible near cooling bath 1.1 in crucible layer 3, carries out cooling.
As a further improvement on the present invention, heat-insulation layer 2 is comprised of graphite felt, high insulating effect.
Embodiment mono-
Use heating plasma evaporative cooling physical vapor method to heat, first the identical or different crucible of the material of selected suitable quantity forms crucible layer 3.When the metal tantalum that need be 5425 ℃ to boiling point heats, first select the tantalum ingot that is applicable to dimensional requirement as internal layer heating object, then in tantalum ingot outside, be coated the graphite crucible of corresponding size, outside crucible layer 3 and between cooling bath 1.1, graphite felt is installed as heat-insulation layer 2, opening heating source 4 heats, after a period of time, the material in inner crucible is divided into 7 three layers of boiling sections 5, melting zone 6, solidification zone, collects metallic vapours as required from boiling section 5.In heating process, to in cooling bath 1.1, pass into cooling water, effectively external crucible is lowered the temperature, guarantee in thermograde region that crucible layer 3 is present in lower than heating object fusing point (lower than 2996 ℃ of the fusing points of tantalum), prevent that crucible self from melting or with tantalum generation physics or chemical reaction, thereby extended service life of crucible.
While using fritting formula crucible heating device, first according to the physical and chemical index of heating object and thermograde, need to select crucible layer 3, the crucible of selected identical material, unlike material is independent or be used in conjunction with, and effectively raises crucible serviceability.Add and hanker, heating object is divided into boiling section 5, fusion zone 6 and solidification zone 7, be that heating object in crucible layer 3 exists obvious thermograde and two physics phase points, be boiling point and fusing point junctional area, during heating, do not need in crucible, to add other materials, crucible does not contact with heating object liquid phase, and exists in lower thermograde region,, with heating object generation physics and chemical reaction, effectively do not avoided the pollution of product.When the material of the crucible in the crucible layer 3 using is not identical, outer crucible can effectively reduce the thermal loss of inner crucible, puies forward high-octane utilization rate, improves the efficiency of heating surface.By passing into cooling water in the cooling bath 1.1 in water cooling box 1, to crucible effective temperature-reducing, guarantee that crucible is in its temperature resistant range, and can Yin Gaowen or contact and cause that physics or chemical reaction cause the consumption to crucible with material-to-be-heated liquid phase, the service life of crucible extended.
