Technical specifications of annealing furnace
This annealing furnace is designed on the basis of the improved
Sendzimir process technology. According to the product grade (CQ)
requirements and the corresponding annealing heat treatment curve,
the strip is heated, insulated, cooled and homogenized. The
recrystallization annealing of the strip is completed and the strip
reaches the required temperature 440-460℃(Low aluminum and low
magnesium) before entering the zinc pot. The strip was successively
heated to 650-720℃ by an open-fire heating furnace, and the oil on
the surface was evaporated. Then, the strip will be put into a
radiant tube reduction furnace to maintain a flexible heat
treatment system. The weak oxide film on the surface of the strip
was reduced in H2+N2 protective atmosphere. Then the strip enters
the insulation section, and the heated strip is kept at the
required temperature according to the requirements of the heat
treatment system. The atmosphere is protected by H2+N2. After the
annealing is completed, it enters the circulating jet cooling
section. According to the cooling rate requirements of annealing
process, the high-efficiency jet cooling device is used to
effectively cool the strip from the heat treatment temperature to
440-460℃(Low aluminum and low magnesium) before entering the zinc
pot. The strip goes into the zinc pot through the hot tensioning
chamber and the furnace nose.
