Abstract
The utility model discloses a heating element for a high-temperature furnace, which is produced by adopting carbon or carbon composite. The heating element is characterized in that the heating element is produced by carbon or carbon composite; compared with the graphite product, the heating element can save energy and material, and has excellent performance of high specific strength, fire resistance, erosion resistance, small coefficient of heat expansion, heat shock resistance, no deformation, no cracking, and the like, thereby being an ideal upgrading product for substituting the graphite heating element.
Description
Technical field:
The utility model relates to high temperature furnace parts such as a kind of polycrystalline silicon ingot or purifying furnace and single crystal growing furnace, specifically a kind of high temperature furnace used heater.
Background technology:
Polycrystalline silicon ingot or purifying furnace and single crystal growing furnace are the capital equipments of photovoltaic industry widespread usage, its maximum operation (service) temperature is up to more than 1600 ℃, at present, often adopt the resistance heating mode, its heater generally adopts three high graphite to make, because of graphite product intensity low, thermal shock resistance is relatively poor, useful life is shorter, has influenced the ordinary production of enterprise, causes enterprise's production cost to increase.In addition, graphite heater mostly is long and narrow U type structure, uses machining graphite, and consumptive material is more, and difficulty of processing is also bigger.Carbon/carbon composite is that a kind of net tire that the charcoal fiber is made and net tire or charcoal cloth and charcoal cloth or net tire and charcoal cloth are compound, form through density, charing and graphitization processing again, have high specific strength, high ratio modulus, high temperature resistant, anti-ablation, little, the anti-rapid heat cycle of thermal coefficient of expansion and indeformable premium properties such as do not ftracture, be adapted to the high temperature field especially, now become or will progressively become one of the important foundation material in fields such as Aero-Space, metallurgy, new forms of energy.
Summary of the invention:
The purpose of this utility model provides a kind of high temperature furnace used heater that adopts carbon/carbon composite to be processed into.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of high temperature furnace used heater, and it is processed into by carbon/carbon composite.
The utility model heater is a tubular or when tabular, which is provided with the flow-guiding radiation groove.
Flow-guiding radiation groove of the present utility model is uniform.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, than the energy-conservation province of graphite product material, and excellent performance, have high specific strength, high temperature resistant, corrosion-resistant, thermal coefficient of expansion is little, the indeformable premium properties such as do not ftracture of anti-rapid heat cycle, is the desirable upgrading products that substitute graphite heater.
Description of drawings:
Fig. 1 is the schematic diagram of heater when being U-shaped;
Fig. 2 is the schematic diagram of heater when being bar-shaped;
Fig. 3 is the schematic diagram of heater when being tubular;
Fig. 4 is the schematic diagram of heater when being tabular.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known, a kind of high temperature furnace used heater, it is processed into by carbon/carbon composite.
The utility model heater is a tubular or when tabular, as shown in Figure 3 and Figure 4, which is provided with flow-guiding radiation groove 1.Described flow-guiding radiation groove 1 is uniform.
The carbon fiber reinforced carbon based composites that described carbon/carbon composite is made up of the pure carbon element, its moulding is combined into prefabricated component by charcoal fleece and cloth through lamination acupuncture, again by making after the chemical vapour deposition (CVD) density.
