What is the daily maintenance method of lub thawv-hom ua haujlwm rauv?

1. When the box-type resistance furnace is used for the first time, the oven must be implemented. The oven time should be four hours at room temperature 200℃. Four hours from 200°C to 600°C. When in use, the furnace temperature must not exceed the rated temperature, so as not to burn and destroy the electric heating element. It is strictly forbidden to inject various liquids and easily soluble metals into the furnace. The resistance furnace is best to work at a temperature below 50 ℃ below the maximum temperature. At this time, the furnace wire has a longer life span.

2. The high-temperature box-type resistance furnace and choke must be operated in a place where the relative humidity does not exceed 100%, and there is no conductive dust, explosive gas or corrosive gas. When the metal material with grease or something needs to be heated, there will be a large amount of volatile gas that will affect and corrode the appearance of the electric heating element, destroying it and shortening the life span. Because this heating should be prevented as soon as possible and do a tightly sealed container or suitable openings to remove it.

3. According to technical requirements, regularly check whether the wiring of the high-temperature box-type resistance furnace and the choke is satisfactory, whether the pointer of the meter is stuck and staying when it is moving, and use the potentiometer to correct the meter due to permanent magnets. , Degaussing, wire swelling, fatigue of shrapnel, damage to the balance, etc.

4. The high-temperature box-type resistance furnace controller should be used within the background temperature range of 0-40℃.

5. Tsis txhob rub tawm lub thermocouple tam sim ntawd ntawm qhov kub siab kom tiv thaiv lub tsho los ntawm tawg.

6. Always keep the furnace clean and clean up the oxygen compounds in the furnace as soon as possible.
