Ultra high temperature box type resistance furnaceThe product is mainly used for sintering and oxidation experiments of metal ceramic materials, composite ceramic materials, nano phase materials, gradient functional materials, nano thermoelectric materials, and crystal materials. The WEF. HE series composite ceramic heating element used in this device can reach a maximum temperature of 2000 ℃ under oxidizing atmosphere conditions, a long-term working temperature of 1950 ℃, a maximum temperature of 2600 ° C under vacuum and inert gas conditions, and a long-term use temperature of 2200 ℃. The usage conditions are subject to the technical parameters at the time of ordering. This device has good thermal shock resistance and can be used for testing the thermal shock resistance of ultra-high temperature materials. The heating element is stable and reliable, with a long service life and low maintenance costs.
Application Scenario:
Materials Science:
Ceramic powder sintering (such as zirconia, silicon carbide);
Synthesis of rare earth permanent magnet materials (annealed at 1600 ℃).
Industrial melting:
Metal melting (platinum, molybdenum alloys);
Glass melting and purification.
Safety operation specifications:
Sample requirements:
The sample must be completely dry and carried in a high-temperature resistant crucible. Direct contact with the furnace is strictly prohibited;
Loading capacity ≤ 70% of furnace volume to avoid thermal circulation obstruction.
High temperature protection:
When the furnace temperature is above 700 ℃, it is strictly prohibited to open the door. Sampling should be allowed to cool naturally to below 200 ℃;
Wear double-layer insulated gloves and goggles, with an operating time of less than 30 seconds.
Emergency response:
In the event of a sudden power outage, immediately cut off the main power supply and perform a step drying oven (200 ℃× 2h → 400 ℃× 2h) after restoration;
The uneven redness of the silicon molybdenum rod requires shutdown for maintenance to prevent local overheating in the hot zone.
