Swedish specialty steel producer SSAB will modernize its continuous hot-dip galvanizing line No. 3 in Hämeenlinna, Finland. The upgrade essentially involves switching the old air-knife into a new air knife system from Duma-Bandzink with strip stabilization and the integration of an inductive booster in the furnace. The conversion measures will be implemented in cooperation with SMS group, Drever International and EMG Automation. The measures will be realized at the end of this year (2017).
The installation of a new Duma-Bandzink Jet-Pro air knife system with EMG eMASS® strip stabilization – in the so-called “Integrated Solution” – will help to save zinc and improve the quality of the coating. The line will be designed for strips between 0.4 to 3.0 millimeters thick and 650 to 1,550 millimeters wide. In the process section, the strips will be zinc-coated at speeds of up to 160 meters per minute. Inductive strip pre-heating to about 350 degrees Celsius will increase the capacity of the furnace.
