Tinplate continuous annealing line

Main data

The annealing of the cleaned strip followed by reduction and surface treatment provides the material in the annealing line with the material and surface properties necessary for tinning and subsequent processing. The very thin material (up to 0.1mm) is processed on the lines at very high speeds (up to 750 m/min). The product range comprises all grades and also contains the qualities T2.5, T5 and DR 10, which cannot be produced by batch annealing. The strip cleaning section has efficient process components including spray and electrolytic cleaning cells. The radiant tube furnace is the heart of the plant and is recognized for its low resource consumption. Due to precise furnace control, the process follows the specified annealing curve exactly. Two 4-high skinpass mill stands are integrated for post-treatment. The first skinpass mill stand adjusts the mechanical-engineering characteristics of the strip by a thickness reduction. The second creates a defined strip surface structure.
