▲ Exit section, coil transport Enamelling furnace The strip passes through a horizontal fur- nace in order to condition the coat. Basi- cally, the holding time is approximately 20 to 25 seconds, in which the hot air is blown directly on the strip. Finally, the outgoing strip has a temperature of about 240 °C.
Cooler ▲ Enamelling furnace Directly after beeing enamelled the strip is cooled down from 240°C to approximately 40°C. The cooling takes place in a horizon- tal stainless steel tank by quenching the strip with demineralized water.
Looper The vertical entry and exit accumulators compensate any down time to avoid stops and provide a continuous strip travel in the ▲ Waterquench process section.
