Tinplate lines


Efficient production of tinplate material

The SMS group offers innovative, technical solutions at all steps of tinplate production for the efficient processing of cold strip into packing material. All the necessary treatment facilities can be delivered from a single source, including mechanical and processing equipment, furnace technology, electrical and automation systems and production know-how. The electrolytic tinning lines are fitted with soluble anodes, which create significant economic, ecological and process-engineering advantages.

Line concepts

Tinplate annealing line

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.

Electrolytic tinning line

Main data
The significant process steps in an electrolytic tinning line are cleaning, leveling, pickling, tinplating, remelting and passivating. All of these process steps must fulfill high requirements in order to guarantee the surface quality of the end material. SMS offers various innovative technologies for tinning lines, which increase the ecological and economic efficiency of the plant.
