Continuous casting of thin slabs

To be competitive, continuous casting of thin slabs requires relatively high speeds to compensate for the slab's low linear mass. From the outset, we have sought to maintain a metal flow per line comparable to that obtained with traditional continuous casting of thick slabs.

In traditional continuous casting, the average casting speed is 1.50 m/min for a 200 mm thick slab and 1.2 m/min for a 250 mm thick slab. Depending on the process, thin slabs can be cast at the speeds shown in table 3.

We can see that the speeds actually achieved on thin-slab continuous casters are still slightly lower than the speeds required to obtain the same metal flux as with traditional continuous casters using thick slabs....
