Usage of atmosphere tube furnace

Many new comers or those who have just come into contact with the tube furnace do not know how to use the atmosphere tube furnace, so the technical personnel of Luoyang sigma furnace industry have brought us this article about the precautions for the use of the atmosphere tube furnace, hoping to help you to use the atmosphere tube furnace.

Note one

The electric furnace operator should have the national corresponding electrical equipment operation qualification, and read the electric furnace instrument manual and other technical documents!

Temperature system operation:

The user's switch board supplies power to the electric furnace. At this time, the program meter is powered on. The instrument (such as P, I, D parameters) is set according to the temperature instrument manual, and the heating program is compiled according to the process requirements. The heating knob is turned on to make the heating power reach 6kW. 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 end of program temperature, the execution time = 0 segment program, and the heating is finished. Turn the stop button to the off position. Turn off the user switch.

Attention two

a. The temperature set by the program shall not be higher than the furnace parameter temperature.

b. When the electric furnace is working, the furnace door shall not be opened. When taking the product, wait until the furnace temperature is below 100 ℃.

c. When heating, the heating power should not exceed 6kW, otherwise the heating element will be damaged. Operation mode

According to the requirements of laboratory, the batch manual loading and unloading is adopted. When charging, place the charging box on the charging basin support, open and take out the sealing end cover at one end of the furnace tube, put into the material box bracket 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 introduced until the oxygen content in the furnace tube reaches the process requirements, and then the temperature rise sintering is carried out. After the product sintering process is completed, a small amount of process atmosphere should be continued to be introduced and the temperature should be lowered until the furnace temperature is lower than the process requirements, and then the furnace tube sealing end cover can be opened to take out the product.
