Description

TECHNICAL FIELD

[0001] The utility model relates to strip steel rectification technical field especially is a strip steel in -furnace rectification device. BACKGROUND

[0002] As an important production raw material of manufacturing industry production, the production of plate strip is bound to go through the processes of hot rolling, cold rolling, leveling, etc. Cold rolling usually adopts continuous rolling production method. After multi-pass rolling, the plate strip resistance is greatly improved due to work hardening, which hinders further rolling thin. Therefore, the plate strip after cold rolling needs to be annealed. This process requires a continuous annealing device. Due to the long mileage winding treatment of the strip steel, the strip steel transverse tension distribution often presents an uneven state. In addition, there are problems such as residual stress or uneven thickness distribution before the strip steel enters the furnace. It is easy to deviate and move during continuous annealing. Lightly, it causes the continuous annealing product to appear sickle bend and single-sided wave problem. Heavy, it affects the production line production and causes production accidents.
