3000℃ ultra-high temperature atmosphere furnace

Release time：2020-06-19 Number of views：3739

Equipment introduction:

The vacuum furnace body is composed of the furnace body, the furnace cover and the related accessories installed on it, the furnace cover lifting mechanism, the bottom frame, etc. The furnace cover has a uniform double-layer water cooling structure, the inner layer is made of non-magnetic stainless steel plate, and the outer layer is made of stainless steel. The furnace cover is equipped with imported two-color infrared thermometer, safety valve, pressure sensor, armored thermocouple interface, air charging valve, pressure vacuum meter, electromagnetic vent valve, handrail, etc., which is easy to operate. The furnace body is equipped with explosion-proof device, thermocouple interface for temperature measurement,and interface for power intake and vacuum pipe. The lifting mechanism of the furnace cover completes the action of opening and closing the furnace cover up and down. The action is driven by the hydraulic jack, and the smooth opening is realized by the manual.

Configuration

Equipment characteristics	1. The double-layer air-cooled structure greatly reduces the surface temperature of the shell; 2. Equipped with a three-dip 4-baked graphite heater with excellent acid and corrosion resistance; 3. The use of graphite cotton felt made of refractory insulation material, small heat loss, help to reduce the use of equipment power; 4. Large sintering space, can be used for industrial production; 5. Touch screen operation, intuitive display of temperature curve;

Cautions	1, always pay attention to the temperature of the furnace cover, furnace body, furnace bottom and water-cooled electrode, can not be hot, otherwise to stop heating, check whether the water is smooth. 2, if the vacuum degree is not pumped, it should be checked whether the oil in the diffusion pump is oxidized, and whether the mechanical pump is aging, such as aging should be replaced in time. 3, when filling protective gas, attention should be paid to the value of the vacuum pressure gauge, which can not exceed the positive pressure (generally 2-3 cells below 0 and about -50Pa, the furnace is still negative pressure). It should be noted that the gas has the characteristics of thermal expansion, if close to the positive pressure, you can open the mechanical pump and pre-extraction valve to remove part of the gas. 4, when loading, be sure not to touch the graphite heating body (saw seam), because the heating body is fragile after burning, causing unnecessary losses. 5, usually should pay attention to the furnace, outside the furnace cleaning, vacuum valve maintenance work. 6, after opening the pump, pay attention to check whether each valve is fully opened, and the connected water pipe is not dripping, if any, it should be eliminated in time.
Service	1 year warranty with lifetime support (warranty does not cover consumable components such as furnace tubes and seals).
