STEEL

The importance of steel is huge, as its scope and uses are infinite: without the availability of steel in large quantities and at low cost, the Industrial Revolution   would not have been possible. Over time, steel production technologies have been perfected and diversified to such an extent that there are now many types of steel, each for different design requirements and markets. The industrial process of steel begins with the extraction of ores containing iron (which is not found in its pure state in nature) at quarries or in mines. As with many metals, the ores extracted are crushed and then milled. These are washed to remove dust and dirt and categorised according to the concentration of the metal content by means of magnetic or gravitational separation. The rest of the process involves flotation , sieving , calibration , drying , calcination  e roasting   of the ores. At this point, the iron ores have been cleaned of most of the impurities and are ready to be molten in the blast furnace

 

Every year, we trade large amounts of semi-finished steel products for the automotive industry - mainly coils, pipes, rods, laminates, etc - and also for the marine, rail and construction industries.
