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.
Wiping Galvanizing Wire System
Asbestos block wipe system
Can
be used to produce zinc coated thin steel wire; The wire enters between
the two wipes and the liquid zinc is squeezed and falls back to the
zinc pool
Nitrogen wipe system
The
nitrogen air knife system is designed to have high thickness zinc
layers between a wide line speed. Each wire leaves the zinc-aluminum
liquid and is protected in a ring by its own nitrogen gas knife
N2 wiping:nitrogen
is blown to the surface of the steel wire by an air knife, which can
smooth the zinc layer on the surface of the steel wire. Meanwhile, the
weight of the zinc layer can be adjusted by controlling the nitrogen
pressure
