Calcium - Wikipedia

Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust

Material selection and product specifiion - Steel Construction

Steel material is supplied in two product forms – ‘flat products’ (steel plate and strip) and ‘long products’ (rolled sections, either open beams, angles, etc or hollow sections). For structural use in bridges these products are inevitably cut (to size and shape) and welded, one component to another., one component to another.

Lime and Calcined Dolomite for Use in Steel Plant – IspatGuru

23/12/2014· Both high calcium and dolomitic lime enjoys its most extensive use as a flux in refining of the steel in BOF and EAF. Lime is particularly effective in removing phosphorus, sulphur, and silica, and, to a lesser extent, manganese. Lime also has important uses in secondary refining of steel and in the manufacture of steel products.
