Tube furnace atmosphere to use

Note that a
Furnace operator should have the corresponding national electrical equipment operation qualifications, and familiar with the electric kiln random instructions and other technical documents!
A temperature system operation:
Users switch plate to furnace power transmission, this time schedule was electric, according to the temperature instructions set the instrument (such as P, I, D parameters), according to the technical requirements of the heating process, open the heating knob, the heating power to reach 6KW. Heating power can be calculated as follows:
Heating power = voltage × Meter Current Meter
Normal heating current is approximately: 22A, heating voltage is approximately: 220V.
Stop heating: temperature program after program execution time = 0 segment, heating ends. The stop button is turned to the closed position. Breaking user switches.
Note that two
a. programmed temperature not higher than the temperature furnace parameters.
b. furnace work, do not open the door. Take the product, should wait until the furnace temperature below 100 ℃.
c. temperature heating, the heating power shall not exceed 6KW, otherwise it will damage the heating element.
Operation
Requirements for laboratory furnace use, loading and unloading using intermittent manual loading, unloading. When loading a cartridge placed in the spout bracket, one end open and take the baked pipe sealing cap, strip cartridge into the cartridge holder, and then sealing cap installed on the furnace tube flange and tighten the clamp bolts. Then Walter craft atmosphere until the oxygen content of the furnace tube when heated sintering process requirements. Product sintering process is completed, the process should continue to Walter atmosphere and make some cool until the temperature is below the furnace process requirements, the only open tube sealing cap remove the product.
