I have been there already a couple of times, alone, with friends and with the family. It is a very informative exhibition about steel - what it is, how it is made, what it is used for. The setting is spectacular - a visitor's center right in the middle of the steelworks, the interior fascinating - a big hall with dozend of enormous, polished, steel bulbs that reflect each other, all sorts of mutli-media channels are used to get the information across and on top you can rest in a cafe and view the steel mill around you. I advise to take the bus tour as well - to get a feel for the sheer size of a major industrial operation involving thousands of tons of material, feeling the heat of 1600°K melted steel flowing out of the iron works and moving into the mill. The bus tour is only for kids above 6years of age, for safety reasons; the centre is open for all; they also do tours, even especially for kids.
Really worth it.
