Box-type  furnace maintenance and precautions:
1. When the box furnace is used for the first time or after long-term use, the oven must be used. Oven time should be room temperature 200 ℃ for four hours. 200 ° C to 600 ° C for four hours. When used, the maximum temperature shall not exceed the rated temperature, so as not to burn the heating element. It is forbidden to pour a variety of liquids and easily dissolvable metal into the furnace. The box furnace is preferably operated below 50 ° C below the maximum temperature, at which time the furnace has a longer life.
2. Box-type furnaces and controllers must be operated at locations where the relative humidity does not exceed 85%, without conductive dust, explosive gases or corrosive gases. Where a metal material such as grease is required to be heated, a large amount of volatile gas will affect and corrode the surface of the heating element to destroy and shorten its life. Therefore, heating should be timely to prevent and do a good job sealing containers or appropriate openings to be excluded.
3. Box-type furnace controller should be limited to the ambient temperature range of 0-40 ℃ use.
4. According to technical requirements, regularly check the electric furnace, the controller of the wiring connection is good, indicating whether the pointer movement when the stuck retention phenomenon, and the use of potential difference calibration instrument due to magnet, demagnetization, wire, shrapnel Fatigue, balance damage caused by the increase in the error.
5. Thermocouple do not pull out at high temperatures, to prevent the burst burst.
6. Always keep the furnace clean, timely removal of oxides and other things in the furnace.
