Refined Iron is obtained by smelting an Iron Ingot. It can also be obtained by placing Iron Ore with Coal Dust in a Rotary Macerator, getting Refined Iron Dust (thus skipping the re-smelting process). This material is used in most Industrial Craft recipes, most notably the Machine Block. Note that Refined Iron can never replace normal iron in a crafting recipe.
If you have the Gregtech addon installed, refined iron is made essentially useless as all recipes using refined iron are changed to use iron plates. This change is reflected in the IC2 achievments page. Recent experimental builds include this feature for Iron Plates, with and without Gregtech
