Horizontal Continuous Bright Annealing Line(HBAL) 

for stainless steel industry

Bright Annealing Line provided by Strong Metal

This line has equiped with inlet and outlet loopers for purpose of continuous annealing process for heat treating steel strips or coils without interruption during loading or unloading materials. 

The annealing process completely operates under controlled atmosphere with ammonia decomposing gas or hydrogen with strong patented concealing devices at the extrances of the furnaces.

This line is integrated with degreasing line for preprocessing the strips or coils before annealing process, which ensures high quality glossy quality of the surface.

This bright annealing line is equiped with strong metal's latest propriety technology on energy efficiency and environment protection.

Strong Metal is a leading supplier of continuous bright annealing lines for stainless steel cold roll mills. Strong Metal's exlcusive patented muffle with featured long time service. Excellent quality and best effeciency of Strong Metal heat treating equipment are the main factors why our customers choose us as their heat treatment equipment supplier in the long run.

Bright annealing is an annealing process performed in a vacuum or a controlled atmosphere containing inert gases (such as Ammonia decomposing gas,  hydrogen). This controlled atmosphere reduces the surface oxidation to a minimum which results in a brighter surface and a much thinner oxide layer. Pickling is not needed after bright annealing since the oxidation is minimal. Since there is no pickling, the surface is much smoother which results in better resistance to pitting corrosion.
