Ultrahigh-power graphite joint preparation method
The invention discloses an ultrahigh-power graphite joint preparation method which comprises the following steps: A, raw material treatment: crushing calcined petroleum coke or pitch coke raw materials to obtain raw material powder; the isostatic pressing technology is adopted for preparing the ultrahigh-power graphite joint, the double-cone-shaped joint blank is directly formed, the machining cutting amount is reduced compared with extrusion forming of a cylindrical blank, the effects of improving the machining yield and further improving the yield are achieved, and compared with an existing forming technology, the ultrahigh-power graphite joint has the advantages of being high in mechanical strength and compact in organization structure; compared with the prior art, the breaking strength can be improved by more than 35%, meanwhile, the designed forming die is limited according to the cutting allowance needed by actual machining, the machining cutting amount can be reduced to the minimum extent, and the machining cost is reduced. Compared with the prior art, the method has the effect of improving the processing yield to the greatest extent (the processing yield can be improved by about 30%).
本发明公开了一种超高功率石墨接头制备方法，包括以下步骤：A、原料处理：将煅烧后的石油焦或沥青焦原料破碎，获得原料粉。本发明采用等静压技术制备超高功率石墨接头，通过直接成型双锥型接头坯料，相对挤压成型圆柱坯体减少了加工切削量，具有提高加工收率，进而提高成品率的效果，且相对现有成型工艺具有机械强度高、组织结构致密的特点，有效提高了接头产品的抗折强度（与现有技术相比，抗折强度可提高35％以上），同时，设计的成型模具，根据实际加工所需切削余量进行限定，可最低限度减少加工切削量，具有最大程度提高加工收率的效果（与现有技术相比，加工收率可提高30％左右）。
