Description
Technical field
The utility model belongs to superhard material HTHP synthesis technical field, is specifically related to the synthetic piece composite conductive steel-ring of a kind of large cavity HTHP.
Background technology
The synthetic of the superhard material such as diamond, cBN all completes under high-temperature and high-pressure conditions.The generation of HTHP acts on the synthetic piece of pyrophyllite by domestic cubic hinge press, the synthetic piece cavity of pyrophyllite two ends have two steel caps sample shutoff in inside cavity, and by steel cap, electric current is transported to graphite-pipe, finally by graphite-pipe heating, make inside cavity obtain the hot environment that is greater than 1200 ℃.Steel cap is outside directly to be contacted with two top hammers, has mainly played sealing, conduction, pressure transmission and thermolysis.
Existing conducting steel ring comprise one end sealing, other end opening and in establish the conducting steel ring matrix of the tubular of cavity, and in the cavity of matrix, be filled with the dolomite that plays insulation pressure transmission effect, matrix is common iron.This conducting steel ring simple in structure is because high pressure synthetic cavity continues to increase, and steel cap diameter continues to increase, and causes distortion and often generation of cracking under steel cap intensity step-down, high pressure, causes production accidents such as " blowing out ".In addition, fill out core separately with dolomite, packed density is low, and pressure transmission and heat insulation effect are poor, causes the temperature distributing disproportionation of synthetic cavity inside even.Therefore directly affected the yield rate that the synthetic superhard material quality obtaining is good, unqualified low, made per unit area yield ability low, product cost is high.
At main patent documentation aspect the relevant heat conduction steel ring in the synthetic field of HTHP, have:
China utility model document < < composite densified conductive steel ring > > (publication number CN 202263572 U, open day on June 6th, 2012) in, introduced a kind of comprise one end sealing, other end opening and in establish the conducting steel ring matrix of the tubular of cavity, in the cavity of matrix, be filled with insulation pressure transmission and add core, described insulation pressure transmission is added core and is comprised successively from top to bottom highly dense material layer and mix the bed of material.The insulation pressure transmission of composite densified conductive steel ring of the present utility model is added core and is comprised successively from top to bottom highly dense material layer and mix the bed of material two-layer.The overall structure of this steel ring and traditional do not have anything to change, and core high cost, poor practicability are added in its insulation pressure transmission.
China utility model document < < synthesizing superhard conductive plug > > (publication number CN 2785699Y for material, open day on June 7th, 2006) in, introduced a kind of synthesizing superhard material conductive plug, it is that electrode by conductor is embedded in and compoundly on insulator becomes a cylinder, electrode wherein includes the electrode A portion of cover body structure and engages with this electrode A portion, the electrode B portion of structure in the form of a ring, electrode B portion engages the electrode C portion that has tube structure, this conductive plug can improve heat dispersion in the synthetic chamber of electrode pair, thereby improve the rate that makes and the quality of synthesizing superhard material, but, complex structure, make more difficult.
Utility model content
The purpose of this utility model is to provide a kind of large cavity HTHP to synthesize piece composite conductive steel-ring, can effectively solve the problems of the prior art, simple in structure, easy to make, with low cost, can improve to greatest extent pressure transmission effect, reduce synthesis pressure, improve device security.
The utility model is by the following technical solutions:
Large cavity HTHP synthesizes a piece composite conductive steel-ring, comprise one end sealing, other end opening and in establish the conducting steel ring matrix of cavity, wherein, the cross section of described conducting steel ring matrix is two circles that the center of circle is identical, diameter is different; In the cavity of described conducting steel ring matrix, be filled with insulation pressure transmission and add core.
As preferably, described insulation pressure transmission is added core and is comprised successively pyrophyllite layer and dolomite layer.
As preferably, described pyrophyllite layer is located at conducting steel ring matrix openings one end.
The beneficial effects of the utility model are:
(1) can guarantee that conductive plug heat insulating ability is good;
(2) can improve to greatest extent pressure transmission effect, reduce synthesis pressure, improve device security;
(3) guarantee there are enough contacts area between the heating dististyle in conducting steel ring and synthetic cavity;
(4) improve its force structure, improved conducting steel ring crush resistance strength;
(5) simple in structure, easy to make, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprise one end sealing, other end opening and in establish the conducting steel ring matrix 1 of cavity, in the cavity of conducting steel ring matrix 1, be filled with insulation pressure transmission and add core, conducting steel ring matrix 1 is followed successively by pyrophyllite layer 3 and dolomite layer 2, pyrophyllite layer 3 is located at conducting steel ring matrix 1 openend, and dolomite layer 2 is located at conducting steel ring matrix 1 blind end.The cross section of conducting steel ring matrix 1 is two circles that the center of circle is identical, diameter is different.
Said structure of the present utility model can guarantee that conductive plug heat insulating ability is good, improve to greatest extent pressure transmission effect, reduce synthesis pressure, improve device security, guaranteeing has enough contacts area between the heating dististyle in conducting steel ring and synthetic cavity, improve its force structure, raising conducting steel ring crush resistance strength.
