How to use the atmosphere tube furnace:
1 Temperature system operation:
The user switch board powers the electric furnace. At this time, the program meter is energized. Set the meter according to the temperature meter manual (such as P, I, D parameters), program the heating program according to the process requirements, and turn on the heating knob to make the heating power reach the rated power. The heating power can be calculated as follows:
Heating power = instrument voltage × instrument current
The normal heating current is about 22A, and the heating voltage is about 220V.
Heating stop: After the program temperature is over, the execution time=0 section of the program, and the heating ends. Turn the stop button to the off position. Disconnect user switch.
2 a. The programmed temperature must not be higher than the electric furnace parameter temperature.
b. Do not open the furnace door when the electric furnace is working. When taking the product, wait until the furnace temperature is below 100°C.
c. When heating, the heating power must not exceed the rated power, otherwise the heating element will be damaged.
According to the requirements of the laboratory, the loading and unloading adopts intermittent manual loading and unloading. When loading, place the material box on the bowl support, open and take out the sealed end cover at one end of the furnace tube, put it into the material box support with the material box, and then install the sealing end cover on the furnace tube flange and tighten the clamp bolt. Then, the process atmosphere is passed through until the oxygen content in the furnace tube reaches the process requirements for temperature-rising sintering. After the product sintering process is completed, a small amount of process atmosphere should be continued and the temperature should be lowered until the temperature in the furnace is lower than the process requirements, then the sealed end cover of the furnace tube can be opened to take out the product.
