Description
Technical field
The utility model is related to a kind of frock, more particularly to a kind of melting siliconising method that is applied to produces carbon ceramic composite material
Carbon carbon frock.
Background technology
Carbon/pottery brake material is a kind of high property developed in recent years after powdered metallurgical material and carbon/carbon composite
Energy brake material, has broad application prospects in fields such as bullet train, automobile, aircrafts.At present, carbon/pottery brake material
Preparation technology mainly has 3 kinds：Chemical vapor infiltration (CVI) technique, precursor dipping-pyrolysis (PIP) technique and melting siliconising
(RMI) technique.Compared with CVI and PIP techniques, RMI techniques have short preparation period, cost low and near-net-shape etc. is excellent
Point, has become competitive Industrialized processing technique, is that production carbon/pottery brake material mainly produces work both at home and abroad at present
Skill.
Needed during melting siliconising method production carbon/pottery brake material the progress siliconising of carbon carbon composite base substrate is anti-
Should, the siliconising operation of prior art uses the graphite reative cell of vertical cylinder structure, reative cell be divided into bottom melt silicon area and
Top reaction zone two parts, pending carbon/carbon compound material base substrate is placed in the top reaction zone of reative cell, silicon material is put
Silicon area heating generation molten silicon is melted in the bottom of reative cell；Molten silicon area and reaction zone are separated with cushion block；Heat the reative cell liter
Temperature is to 1650 DEG C~2000 DEG C and vacuumizes, and is incubated 2~8 hours, and molten silicon enters the top reaction zone of reative cell by cushion block,
Adsorbed by carbon/carbon composite billet surface and react generation carborundum, it is low that natural or control is cooled to reaction chamber temperature
In 150 DEG C, that is, obtain carbon/pottery brake material.Because the mechanical property of graphite material is relatively low, above-mentioned graphite reative cell, molten silicon earthenware
Crucible, pillar and cover plate are in hot environment and silicon liquid and silicon steam reaction production carborundum.Due to heating-cooling repeatedly in production process
With the effect of thermal stress, easily ftracture, service life is short；Simultaneously because reative cell serious cracking influences the siliconising effect of product.Lead
Cause batch production carbon/pottery brake material product quality uniformity is unstable and low production efficiency.
Utility model content
The deficiency that the utility model exists for the graphite reative cell of existing melting siliconising method production carbon ceramic composite material, is carried
It is applied to the carbon carbon frock that melting siliconising method produces carbon ceramic composite material for a kind of.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：
It is a kind of to be applied to the carbon carbon frock that melting siliconising method produces carbon ceramic composite material, including several self connections
Cylindrical structure reative cell, the bottom surface of the reative cell is provided with the crucible for holding silica flour, if being placed with inside the crucible
Dry cushion block, the top of the cushion block, which is placed, needs silication workpiece base substrate, and the top of the reative cell is sealed by upper cover plate, described
Reative cell, crucible, cushion block and upper cover plate are made by carbon carbon composite.
The beneficial effects of the utility model are：Carbon carbon composite has elevated temperature strength height, thermal shock resistance good, with silicon liquid
And the higher advantage of mechanical property after silicon steam reaction generation carbon/carbon-silicon carbide, Reusability do not ftracture, it is reusable and
Service life is long.The shortcoming that graphite frock is easy to crack, service life is short can be effectively solved, siliconising effect is good, and material property is consistent
Property it is stable.

Embodiment
Principle of the present utility model and feature are described below in conjunction with example, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in Figure 1, 2, it is a kind of to be applied to the carbon carbon frock that melting siliconising method produces carbon ceramic composite material, including several
The reative cell 1 of the cylindrical structure of self connection, the bottom surface of reative cell is provided with the crucible 2 for holding silica flour 3, crucible internal pendulum
Some cushion blocks 4 are placed with, the top of cushion block, which is placed, needs silication workpiece base substrate 5, and the top of reative cell is sealed by upper cover plate 6, instead
Room, crucible, cushion block and upper cover plate is answered to be made by carbon carbon composite.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
