THE MAIN STEPS OF THE MANUFACTURING PROCESS
GTS Industries receives “mother slabs” mostly supplied by Dillinger Hütte, the parent company.
The slabs are first inspected and finished, and then reheated in the two pusher-type furnaces. The temperature can reach 1 200°C.
After high-pressure de-scaling, the slabs move on to the rolling mill. They are processed by the two four-high stands, which are among the most powerful in Europe: the first for “rolling to width”, the second for “rolling to thickness”.
Some plates can be subjected to accelerated cooling (water).
The mother plates next head to the hot levelling machine and are then stacked. After cooling down to room temperature, the plates proceed to the “finishing areas” where surface checks and internal soundness tests are performed and possibly thermal treatment is carried out in one of the two furnaces. Then the plates are cut to the requested width and length.
Mechanical testing is carried out in order to determine the properties.
Some plates are shot-blasted and painted.
The plates can then be shipped to the customer by truck, ship or rail.
The manufacturing quality is guaranteed thanks to a highly computerised process (product traceability).
