Stainless steel bracket
The stainless steel bracket is fixed vertically on the mobile shelf. The quartz tube and flange are fixed on the stainless steel bracket through the support plate, which is very strong and compact.
Lower vacuum flange
A vacuum cavity is welded on the lower stainless steel flange, and a furnace door is opened on the vacuum cavity. Materials can be taken from the furnace door, and the cavity is welded with KF25 connector, KF16 interface and inlet valve, and installed on the KF25 connector. There is a vacuum baffle valve, a 1 meter long bellows is connected to the valve and the vacuum pump, and the KF16 interface can be connected to a vacuum gauge
Upper vacuum flange
The upper vacuum flange is equipped with a pressure gauge and an air outlet valve. The flange cover is equipped with two types. One has a glass observation window to observe the melting of the material in the tube. A thermocouple can program the temperature of the material.
The refractory device in the furnace tube is made of Mitsubishi 1900 type alumina fiber with a maximum temperature resistance of 1800 ° C. The shape of the insulation material is like a thermal insulation barrel. The top can be opened to hold graphite crucibles and materials. You can observe the melting of the material in the crucible or insert a thermocouple from this hole
Temperature control system and thermocouple
Adopt PID control, can programmatic temperature control heating of the material, can manually adjust the current output size at the same time, the device has over temperature protection
Temperature control accuracy
+/- 5 ℃
Tempered glass and aluminum profiles with fixed tempered glass are installed around the furnace tube, which can protect the safety of users.
