Box type atmosphere furnace belongs to a type of high-temperature electric furnace. What should we pay attention to during the use process?
1. Box type atmosphere furnace should pay attention to whether the joint gasket is complete. If it is incomplete, the new gasket provided with this machine should be used to install it to prevent oil leakage under high pressure.
2. The atmosphere furnace should open the iron door above the dynamometer to check whether the wire of the small hammer is wound in the groove of the pointer coaxial small gear, and the length of the wire rope should be Appropriate, not too long or too short, with a limit of * not touching the evacuation diaphragm. Shorten it to one revolution of the small gear, and the time hammer will not touch the small gear
3. The testing machine should be installed in a clean, dry, and uniform temperature house. At the same time, the possibility of conducting long beam bending tests on the machine and the possibility of using a mirror extensometer for testing should be considered. Therefore, sufficient space should be left around the testing machine. The atmosphere furnace is widely used in early experiments in laboratories, industrial and mining enterprises, and scientific research institutions, with various types of reducing atmosphere, inert atmosphere, hydrogen nitrogen mixed atmosphere, etc, The rated temperatures are 1100 ℃, 1300 ℃, 1500 ℃, 1600 ℃, and 1700 ℃, respectively. Different heating elements are used according to different atmospheres and temperatures. The models are complete, safe, and reliable, and can also be specially manufactured to meet different process experiments The vacuum box atmosphere furnace system adopts special design technology, which is safe and convenient to operate, with a good vacuum degree. The maximum vacuum degree can reach 20kPa, good sealing performance, and long vacuum holding time. This atmosphere furnace can be filled with high-pressure gas, with an atmosphere pressure limit of 0.1MPa. It adopts unique sealing technology, which can maintain pressure for a long time, has good safety performance, and is easy to operate In order to maintain a certain carbon potential in the furnace, in addition to controlling the stability of the atmosphere components, automatic control of the furnace atmosphere is also necessary. Therefore, various control instruments are required to continuously or regularly measure and adjust the gas supply in the furnace. The mixture of reducing gas and air reaches a certain mixing ratio, which can easily cause explosion at a certain temperature. Therefore, explosion-proof devices are installed in the front and rear chambers, quenching chambers, and slow cooling chambers of the furnace. The control system for gas supply and exhaust of the box atmosphere furnace also needs to have explosion-proof measures
