Furnace Type Online Annealing Furnace Natural Gas
The entire furnace adopts a countercurrent open flame heating furnace type, with separate temperature control and atmosphere adjustment for each section. Adopting hot air and gas heating technology, the main characteristics of this furnace type are the use of open flame heating, under oxygen and over oxygen combustion, and control.
Compared with other furnace types, the full hot air control technology can save gas energy consumption to the greatest extent and reduce production and operating costs
The ignition of each burner, flame detection, temperature control, air and gas ratio coefficient, safety faults, etc. are all fully automatically controlled by the program.
