About Pit Type Electric Furnace - PF
Pit type sealed retort furnaces are of a cylindrical design vertically erected with a positive sealing mechanism on top in order to contain and preserve heat and atmosphere during a process cycle. The job or charge is loaded into a retort which functions as the chamber of the furnace and the retort is heated externally electrically. In process industries these furnaces can also be used in high pressure applications with temperatures from 800°C to 1200°C. These Furnaces can also be used in high Vacuum system for alloys annealing. These are open laid in a pit to make most of the space available and charges can be loaded and unloaded easily. These are manufactured considering working controlled atmospheres with inlets for diffusion and distribution of cracked ammonia, hydrogen etc.
