Preferably, in above-mentioned carbon carbon lid plate, reinforcement is specially ceramic wafer.
The carbon carbon lid plate for polycrystalline ingot furnace that the utility model is provided, including center is provided with the cover plate sheet of interstitial hole Body, also including being fixedly connected on the reinforcement of the insulation high-temperature-resistant on cover board body surface, reinforcement is used to prevent cover board body from sticking up It is bent.Using the utility model provide for polycrystalline ingot furnace carbon carbon lid plate when, by the surface of cover board body fix connect It is connected to the reinforcement of insulation high-temperature-resistant so that cover board body will not occur warpage because of hot environment easily in use Property become, then cover board body is also just not easy to access the top heater of polycrystalline ingot furnace, as long as cover board body and top heater Maintain a certain distance, it is possible to avoid the dangerous situation that Arcing occurs, improve the security that polycrystalline ingot furnace is used.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.
The structural representation of the carbon carbon lid plate for polycrystalline ingot furnace that Fig. 1 is provided for the utility model embodiment;
Fig. 2 is the main structure diagram of Fig. 1.
Marked in accompanying drawing as follows:
Cover board body 1, interstitial hole 2, reinforcement 3, screw 4.
Specific embodiment
The utility model embodiment discloses a kind of carbon carbon lid plate for polycrystalline ingot furnace, to avoid carbon carbon lid plate from making There is buckling deformation during, improve the security of polycrystalline cast ingot process.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to the carbon carbon lid plate for polycrystalline ingot furnace that Fig. 1 and Fig. 2, Fig. 1 are provided for the utility model embodiment Structural representation, Fig. 2 is the main structure diagram of Fig. 1.
Embodiment of the present utility model provides a kind of carbon carbon lid plate for polycrystalline ingot furnace, including center is provided with centre The cover board body 1 in hole 2, also including being fixedly connected on the reinforcement 3 of the insulation high-temperature-resistant on the surface of cover board body 1, reinforcement 3 is used for Prevent the warpage of cover board body 1.
Using above-described embodiment provide for polycrystalline ingot furnace carbon carbon lid plate when, by the surface of cover board body 1 It is fixedly connected with the reinforcement 3 of insulation high-temperature-resistant so that cover board body 1 in use will not easily because of hot environment Generation warpage properties become, then cover board body 1 is also just not easy to access the top heater of polycrystalline ingot furnace, as long as the He of cover board body 1 Top heater is maintained a certain distance, it is possible to avoid the dangerous situation that Arcing occurs, and is improved polycrystalline ingot furnace and is used Security.
In order to optimize the using effect of reinforcement 3 in above-described embodiment, including the reinforcement 3 being arranged in pairs, reinforcement 3 is closed It is symmetrical arranged in interstitial hole 2.It is preferred that paired and symmetrical setting reinforcement 3 so that reinforcement 3 shares the heat change of cover board body 1 The effect of shape stress can be more uniformly distributed, and ensure that the various pieces of cover board body 1 are all subject to relatively stable tension effects.
