Abstract
The utility model relates to the technical field of high-temperature material preparation and specifically relates to a graphite heating body of a high-temperature vacuum resistance furnace. The graphite heating body of the high-temperature vacuum resistance furnace comprises graphite heating body laths, wherein U-shaped sheet connecting members with screw holes are arranged among the graphite heating body laths; and the U-shaped sheet connecting members and the graphite heating body laths are fastened through bolts and nuts. As U-shaped sheet type carbon/carbon composite material connecting members with high temperature resistance, heat impact resistance as well as high toughness and carbon/carbon composite material bolts and nuts are adopted for connecting the graphite heating body laths, all the joints are disconnected with the furnace body and the joints are located in a uniform temperature zone inside the furnace, the graphite heating body of the high-temperature vacuum resistance furnace, disclosed by the utility model, has the advantages of uniform temperature, no influence from heat gradient and heat impact, very high intensity of the joints and reliable connection, and can greatly improve operational reliability of the device.
Description
Technical field
The utility model relates to the high-temperature material preparing technical field, is specifically related to a kind of high temperature vacuum resistance furnace graphite heater, and the utility model is mainly used in high-temperature material sintering, heat treatment, fields such as carbon material charing, graphitization, high temperature deposition.
Background technology
Vacuum high temperature furnace mainly comprises induction furnace and resistance furnace two big classes at present.Induction furnace leans on crucible to absorb the induced current heating, so reliability is higher owing to there is not the high temperature electric connection point; But also exist power supply architecture complicated; The vacuum chamber utilance is extremely low, once drops into high, shortcomings such as occupation of land is big, ultra-large type body of heater realization difficulty, and its use receives certain limitation.The pyrographite resistance furnace has low cost of manufacture, the advantage that the heat efficiency is high, but because tie point is too much; And adopt the graphite connector, connector is owing to receive factor affecting such as thermal shock, inductance impact, vibrations; Tie point relaxes very easily and then breaks down; Equipment dependability is very low, has had a strong impact on the raising of production efficiency, has increased the equipment use cost.
Summary of the invention
The utility model exists tie point too much to present graphite resistor furnace, and tie point is connected with the water cooled furnace wall through the insulating ceramics ring, causes thermal losses big; The tie point thermal gradient is big, there is big thermal stress in the cold and hot connector, and shortcomings such as easy damage provide a kind of high temperature vacuum resistance furnace graphite heater; Effectively solve the thermal gradient thermal shock effect; Tie point intensity is provided, has connected reliably, improved the operating reliability of equipment.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:
A kind of high temperature vacuum resistance furnace graphite heater comprises the graphite heater lath, is provided with the U matrix connector that has screw between the said graphite heater lath, and U matrix connector and graphite heater lath are fastening through screw bolt and nut.
Said U matrix connector, spiral and nut are processed by carbon/carbon composite.
Said graphite heater lath is not connected with body of heater with tie point between the U matrix connector.
The utility model adopts high temperature resistant heat shock resistance high tenacity U matrix formula carbon/carbon compound material connector to carry out being connected of graphite heater lath with carbon/carbon composite bolt, nut; All tie points all are not connected with body of heater, and tie point is in uniform temperature zone in the stove, and temperature is even; No thermal gradient thermal shock effect; Adopt charcoal charcoal connector and charcoal charcoal bolt in addition, tie point intensity is very high, connects reliable; The operating reliability of equipment can be increased substantially, 4 meters manufacturings of crucible diameter can be realized making with the ultra-large type graphite resistor furnace.
