In order to prevent steam leakage, the maintenance steam in the bright furnace should maintain a certain positive standard pressure. If the maintenance gas is radon gas, it should generally be above 20KW.

1. Maintain standard pressure
In order to prevent steam leakage, the maintenance steam in the bright furnace should maintain a certain positive standard pressure. If the maintenance gas is radon gas, it should generally be above 20KW.

2. Quenching atmosphere
Generally pure hydrogen is used as the quenching atmosphere of the Stainless Steel Antenna. Atmosphere purity is preferred to be higher than 99.99%. If there is another rare gas in the air, the purity of pure hydrogen can be moderately reduced, but it is strictly forbidden to carry too much CO2 and water vapor.

3. Pay attention to whether the annealing temperature reaches a specific temperature
Stainless Steel Antenna heat treatment process is generally heat treatment tempering heat treatment process or quenching. The temperature range of the processing technology is 1040~1120℃, and the stainless steel pipe can also be inspected in the inspection hole wall of the quenching furnace during the production process. The stainless steel pipe in the quenching zone should be in the shape of an incandescent lamp, without softening and slack.

4. There must be no steam in the stove
First of all, be sure to constantly check whether the furnace wall is dry, and then make holes. When installing the furnace for the first time, be sure to dry the raw materials of the equipment body. The second is to check whether there are any residual water marks on the Stainless Steel Antenna that enters the furnace. Some stainless steel pipes are likely to have holes. At this time, do not bring all the stored water to the bright furnace, otherwise it will have an adverse effect on the whole process of stainless steel production.

5. Furnace wall sealing characteristics
The bright quenching furnace must be airtight and blocked from outside air. Generally radon gas is used as a maintenance vapor. Only one exhaust pipe opens on the furnace wall. Its role is to promote the ignition of hydrogen. The inspection method is to wipe water at each interface of the quenching furnace to observe whether there is steam leakage. The most vulnerable part is the area where the quenching furnace enters and exits the pipeline. The sealing ring here is very easy to wear and must be regularly inspected and replaced.
