Carbon/carbon stove for brazing furnace and preparation method of carbon/carbon stove

The invention relates to the technical field of brazing furnaces, in particular to a carbon/carbon stove for a brazing furnace and a preparation method thereof.The carbon/carbon stove for the brazing furnace is prepared by alternately laying a plurality of layers of carbon cloth and a plurality of layers of net tires, manufacturing a prefabricated plate through a needling technology and then sequentially conducting chemical vapor deposition, liquid phase impregnation, carbonization and high-temperature graphitization. According to the carbon/carbon plate, the weight of the carbon/carbon plate loaded into a furnace is greatly reduced, the heat loss is reduced, and the carbon/carbon plate has the additional advantage of long-term thermal stability. The carbon/carbon stove is small in deformation, high in flatness and long in service life in the using process. 本发明涉及钎焊炉技术领域，具体涉及一种钎焊炉用碳/碳炉具及其制备方法，由若干层碳布和若干层网胎交替铺层，并通过针刺工艺制成预制体板材，再依次通过化学气相沉积、液相浸渍、碳化、高温石墨化制备而成。本发明所述碳/碳板材不仅大幅度降低了装入炉内的重量，减少了热量的损失，还有长期热稳定性的额外优点。碳/碳炉具在使用
