Annealing is an important metal and alloy processing process in heat treatment production, which aims to improve the performance of materials by controlling heating and cooling. The essence of annealing is to heat the steel to austenitization and then perform pearlite transformation. The structure after annealing is close to the equilibrium structure.

Purpose of annealing:

1. Reduce hardness and strength and improve machinability.

2. Eliminate or reduce residual stress, stabilize size, reduce deformation and crack tendency.

3. Refine grains, adjust structure, and eliminate structural defects.

4. Uniform material structure and composition, improve material properties or prepare for subsequent heat treatment.

Classification of annealing methods:

1. Complete annealing

2. Isothermal annealing

3. Incomplete annealing

4. Spheroidizing annealing

5. Homogenization annealing

6. Stress relief annealing

7. Recrystallization annealing

Annealing equipment:

Strong Metal customized continuous stainless steel strip bright annealing line

Use: used for continuous bright annealing of stainless steel strip, ordinary steel, alloy steel, spring steel, copper, etc.

Strip thickness: 0.1~3MM

Band width: 250~1450MM

Natural gas (LNG), liquefied petroleum gas (LPG) and diesel can be selected as the main heating method for the furnace body.

The unit of the stainless steel strip bright annealing production line consists of an inlet section, an inlet looper, a degreasing section, a process section, an outlet looper, and an outlet section.

The use of automated control forms an ultra-highly integrated and precision-controlled  line, realizing the technical integration and innovation of the continuous production line of stainless steel cold-rolled strip.
