Precautions for the use of muffle furnace
 

muffle furnace

  1. The heating rod of the muffle furnace is very fragile and fragile. Do not touch it. After any heating rod is damaged, the equipment cannot be heated, and it is expensive to replace.

  2. When opening and closing the door of the muffle furnace, lightly open and close, the protective door is damaged and the seal is not tight.

  3. When using the muffle furnace, the power switch sequence is to turn on the power first, then turn on the heating, and finally adjust the temperature. The sequence cannot be reversed, and there is no sequence requirement when shutting down. 4. When the muffle furnace is at a high temperature above 900℃, the furnace door cannot be opened to prevent the heating rod from being chilled and brittle due to cold air.

  5, Ma muffle furnace temperature in the high temperature stage, if you want to cool down, open the door can not be directly cooled, cooling should be shut off or thermostat.

  6, MA muffle furnace at 1200 deg.] C or more, the human eye can not see directly inside a muffle furnace, the heating rod temperature high brightness may create eye burns. 

  7. When heating items, pay attention to the melting point of the items and place the items in a high-temperature resistant vessel. If the heated items melt and flow directly into the furnace, the furnace will be damaged and the muffle furnace can no longer be used. 

  8. In the heating phase, the muffle furnace current is adjusted to 90%, and in the heat preservation phase, the muffle furnace current is adjusted to 50%.

  9. Turn off the main power switch of the maintenance equipment, especially when replacing the silicon molybdenum rod, remember to clear the equipment status and details before replacement.

  10. Use personnel to protect themselves; high temperature gloves and protective glasses. 

  11. When adjusting the temperature, the temperature of the first two sections cannot be adjusted. The temperature of the first two sections is for protection equipment. If adjusted manually, the silicon molybdenum rod will be damaged.

  12. Don't move if you don't understand!
