More Information
Summary:The utility model provides a compounded pyrophyllite block for the filed of metallurgy technology; the utility model is mainly characterized in that the inner wall of a pyrophyllite sleeve is embedded with a sleeve-shaped liner tube formed by prepressing dolomite and graphite; the pyrophyllite block out of the liner tube is formed by packing and compound pressing two semi-sleeve pyrophyllite blocks. The dolomite powder and the graphite are mixed with a weight proportion of 100:2, and the NaSO4 solution of ( 6 plus 0.6) percent is added, finally, the liner tube is produced by prepressing; moreover, the pyrophyllite powder is mixed according to thick, medium and thin weight proportion of 8:15:7, and the NaSO4 solution of ( 6 plus 0.6) percent is added, finally, the pyrophyllite block is produced by prepressing. Compared with the prior art, the compound pyrophyllite block not only can solve the phase change problem in high pressure and high temperature, but also have perfect heat preservation, pressure transferring and sealing effect, and the utility model is good for the long-time synthesis of high-quality diamond, as well as reduces the hammer consumption.
