Graphite Heating Rods For High Temperature And Vacuum Furnaces
Product deatils:
Graphite rod for electric heating elements in high-temperature vacuum furnaces
The main purpose of graphite rods: graphite rods are commonly used in the metallurgical and mechanical industries. They are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000 ° C. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in a neutral atmosphere or reductive Use in atmosphere. They are often used as electric heating elements in high-temperature vacuum furnaces.
