Description
Technical field
The utility model relates to sintering furnace technical field, is specifically related to a kind of high temperature air pressure sintering furnace.
Background technology
Along with density to material of scientific research and production field, the crystal structure particular/special requirement of material improve constantly, the sintering experiment of some materials need to be used under high-temperature and high-pressure conditions and carry out.In recent years, people improved constantly the demand of HTHP sintering, under HTHP, the heat transfer type in burner hearth under normal temperature and pressure, be different, the chemical reaction of the material under HTHP under normal temperature and pressure, be also different.At present, people are relatively less to the research of high-temperature high-pressure apparatus, particularly the manufacture difficulty of the above HTHP sintering furnace of 1600 degree is relatively large, graphite heater utilizes more than can easily be heated to 1600 degree, but because the non-oxidizability of graphite is poor, can not be used for the heating under micro amount of oxygen or aerobic conditions.At normal temperatures and pressures, Si-Mo rod can be used for being heated to sintering furnaces more than 1600 degree, and the non-oxidizability of Si-Mo rod is stronger, in the time that Si-Mo rod is used for the heater element under HTHP aerobic conditions, the terminals of Si-Mo rod, usually due to the contact resistance oxidation of generating heat greatly, often occur that cold junction melts phenomenon, and the furnace roof of large high-temperature high-pressure oxidation stove also usually subside, burner hearth is shorter service life, is also easy to cause security incident.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and a kind of high temperature air pressure sintering furnace is provided.
The utility model is for solving the problems of the technologies described above, the technical scheme providing is: a kind of high temperature air pressure sintering furnace, comprise furnace shell, furnace bottom, bell, calandria and wiring fixture, furnace shell, furnace bottom and bell are Double-layer water recycle metal housing, and wiring fixture is silver or the anti-oxidant fixture of platinum matter.In described furnace shell, be provided with the burner hearth with stainless steel casing, stainless steel casing is fixedly connected with furnace shell inwall, calandria is square calandria, the cold junction of calandria is provided with silver coating, two cold junctions of described calandria stretch out from the sidewall of burner hearth stainless steel casing, and be placed in the cavity forming between stainless steel casing and furnace shell, and be fixedly connected with between calandria and stainless steel casing.In the cavity forming between described stainless steel casing and furnace shell and burner hearth internal cavities, be all filled with insulation material.
beneficial effect
Sintering furnace of the present utility model is provided with the burner hearth of stainless steel casing in furnace shell, and the cold junction of calandria stretches out from the sidewall of stainless steel casing, and be placed in the cavity forming between stainless steel casing and furnace shell, efficiently solve the problem that the roof of the furnace of HTHP stove easily caves in, silver coating is set and uses the wiring fixture of silver or platinum matter to overcome the problem that calandria cold junction easily melts at the cold junction of heater.
