Hartlepool Steelworks c1940

What we know about this image :

Workman in the steelworks

Here an operator is throwing salt on to a plate which is being rolled. When the plate goes back between the rolls for its next pass the salt is breaks down the scale (iron oxide) and the water washes it away. This method has long since ceased to be a process in steel making.
