Sloping diamond synthesis block

Abstract

The invention discloses a sloping diamond synthesis block, which comprises a graphite column, conductive steel rings at the two ends of the graphite column, and pyrophyllite blocks in the periphery of the graphite column and the conductive steel rings; the conductive steel rings are filled with pyrophyllite rings and dolomite rings; the periphery of the graphite column is provided with a heating element; an insulating element is arranged between the heating element and the graphite column; the pyrophyllite block consists of two half blocks buckled with each other; and a graphite column cavity is formed in the middle of the two buckled half blocks, and each half block is in a triangular prism shape. The sloping pyrophyllite blocks are formed, and a joint seam of the sloping pyrophyllite blocks is at the corner of the pyrophyllite blocks, and is staggered from the middle part of a non-heating top hammer; hot gas cannot rush to the non-heating top hammer, so that thermal fatigue of the non-heating top hammer can be obviously mitigated, and the top hammer is effectively protected; and the number of the broken non-heating top hammers is greatly reduced, the broken hammer accidents are reduced, the consumption of the hard alloy top hammer is greatly reduced, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of superhard material synthesis, in particular to an italic diamond synthesis block. Background technique [0002] In the field of superhard material synthesis, the static pressure catalyst method of the six-sided top synthesis press is mainly used in China. The six hinged beams corresponding to the six-sided top synthetic press of the static pressure catalyst synthetic diamond have six top surfaces, which are: the right top surface direction, the front top surface direction, the upper top surface direction, the left top surface direction, and the rear top surface direction. The direction of the top surface and the direction of the lower top surface, and the directions of the left, rear and lower top surfaces are also called fixed top surfaces. The hexahedral composite block under ultra-high temperature and high pressure conditions is composed of a graphite column made of graphite and catalyst mixed powder,...

Problems solved by technology

During the heat release process of diamond growth, accompanied by gas generation, which exists inside the pyrophyllite block, the above-mentioned gas tends to rush out from the bonding seam between the two halves of the assembled block, and the part where the gas rushes out corresponds to Four non-heated top hammers, the hot gas rushing to the non-heated top hammers will accelerate the thermal fatigue of the non-heated top hammers, and even crack the non-heated top hammers, resulting in a split hammer accident
