Graphite is a container made of ceramics, so it has very good high temperature resistance and can be used in industrial metal sealing or casting. The thermal conductivity is good, but it is simply oxidized and the damage rate is large, while the silicon carbide cymbal is compared with graphite grid volume and has a long service life.
Many people are not preheated when they use the new graphite 时, causing graphite to break, which brings danger to your personal safety and property security.
1. The new graphite uses the first 4-5 hours to put it on the oil furnace to preheat, which will help the dehumidifier surface.
2. Put charcoal or wood in the pupa for about four hours before using the new graphite. It is assisted by the dehumidification.
3. The warm-up time of the warming in the new graphite furnace is as follows: 0 ℃ -200 ℃ Slow heating 4H oil 0 ℃ -300 ℃ Slow heating 1h electricity 200 ℃ -300 ℃ Slow temperature 4H furnace 300 ℃-300 ℃- 800 ℃ Slow temperature 4H furnace 300 ℃ -400 ℃ Slow heating 4h 400 ℃ -600 ℃ Rapid heating and persisting 2H
4. After the furnace is stopped, the preheating time is as follows: oil furnace and electric furnace: 0 ℃ -300 ℃ Slow temperature at 1h 300 ℃ -600 ℃ Slow heating 4H 600 ℃-Quickly heating up to the required degree A. Electric furnace. : It is good to keep the insulation during the stop work, and the temperature is set at about 600 ° C; if you do not keep the heat, you need to scoop out as much as possible without leaving too much; if you encounter power, you need to take out the material agile. b. Oil furnace: After the stove is stopped, the soup should be cleaned as much as possible.
