Basic knowledge you must master in the experimental resistance furnace

Basic knowledge of experimental resistance furnace:
　　

1. When titanium alloy is placed in the experimental electric furnace, nitrogen is not suitable as the refrigerating gas, because titanium and nitrogen respond at high temperatures to produce orange-yellow titanium nitride.
　　
2. The movable connection parts of the experimental electric furnace are all sealed with O-shaped rubber rings, and circulating water is passed through this part.
　　
3. When steel parts are quenched under vacuum, vacuum quenching oil should be used, which has a lower saturated vapor pressure.
　　
4. The conditioning of the experimental electric furnace should be under vacuum or pure nitrogen to avoid inhalation and moisture absorption when it is not needed.
　　
5. The pressure rise rate of the domestic experimental electric furnace should be less than 1.33Pa/h, and the standard of some foreign companies is 0.67Pa/h
　　
6. Vacuum heating focuses on radiation, and the workpiece should maintain a distance in the furnace.
　　
7. During the heating process, the workpiece and the material in the furnace will release air, which reduces the vacuum.
　　
8. The heating temperature for vacuum stress relief annealing, vacuum annealing, vacuum solution treatment and vacuum time limit is usually the same as the room temperature for basic solution.
　　
9. The vacuum furnace should have fast cooling equipment. The pressure of the cooling water needs to exceed 0.2Mpa, and the flow rate should be adjustable.
　　
10. Cooling gas: Nitrogen with 99.995% purity is generally used for steel, 99.999% nitrogen or argon is used for high-temperature alloys, and 99.995% argon is used for titanium alloys.
　　
11. Raising temperature: After putting in the workpiece, it is generally possible to raise the temperature when it is pre-pumped to 6.67Pa
