Abstract

The invention discloses a processing method for producing isostatic cylindrical graphite by using an isostatic pressing graphite barrel forming die, and relates to the technical field of isostatic pressing graphite processing. The processing method of isostatic pressing cylindrical graphite, the mold comprises a mold steel barrel, a plastic bag, an inner core barrel, a base, a support ring and an evacuation tube, and the diameter of the inner core barrel is smaller than the diameter of the mold steel barrel and the plastic bag, The plastic bag and the inner core barrel are installed on the base, the base is sleeved on the bottom of the lower end of the mold steel barrel, the plastic bag is laid in the gap between the inner core barrel and the mold steel barrel, and the vacuum pipe is connected to the mold steel barrel. The inside of the plastic bag is communicated, and the support ring is sealed and installed at the inner opening of the plastic bag to seal and vacuumize; the method includes a plurality of steps, and the present invention has the advantages of being able to mass-produce large-diameter barrel materials, and optimizing the internal Structural defects, good quality and high isotropy.

Description

technical field [0001] The invention belongs to the technical field of isostatic graphite processing, and in particular relates to a molding die for isostatic graphite cylinder material and a processing method for isostatic graphite cylinder. Background technique [0002] The Czochralski single crystal furnace in the photovoltaic industry is the main technical equipment for the production of Czochralski single crystal. As the diameter of the Czochralski single crystal becomes larger and larger, when users use circular static pressure graphite to process large-diameter annular graphite components, they choose graphite The material diameter is also increasing. There are also more and more useless "coring materials" graphite cut from the inside. "Coring materials" can account for 50-60% of the production cost of graphite thermal field, which brings great benefits to downstream graphite users. cost pressure. In order to meet the market demand, powerful isostatic graphite manuf...
