Description

For this project the goal was defined as “Construction of a continuous annealing and pre-treatment line for automotive body sheet complete with building, cranage and utilities”. The owner of the project (Corus Aluminium n.v.) planned a yearly capacity of 82.000 tonnes per year. Therefore the line speed specified at 100 m/min. The building is 240 m long and is 23 m high. All specified equipment is intalled in the building. The length of the line is 228 m, with 2 levels. Total steel structures of about 1500 T support the building as well as the installed equipment. The equipment consists of a fully automatic uncoiling and recoiling sections, degreasing, floating furnace and quench, tension leveller, pickling, passivation and dry lube.
