LOW-ALLOY STEEL PICKLED AND ANNEALED WIRE ROD

The production of pickled and annealed wire rod begins with the arrival of the raw materials (iron Scrap, DRI, cast/pig iron, alloying elements, slag forming elements) to the plant. 

The scrap iron, the slag forming elements, alloying element and, if used, the DRI or pig iron/raw cast iron, are placed in the electric arc furnace to be melted and casting to obtain the ingots.

The ingots are heated and moved to the first rolling mill for the first reduction to obtain the blooms, the blooms can be moved to the second rolling mill for the second reduction to obtain the bars and the billets. After the rolling of the blooms, billets and bars are grinded and sheared to the right length.

The finished billets are heated in a furnace connect to the wire rod rolling mill. When they reach the correct temperature are rolled in a rolling train until they reach the desired diameter. 

After the rolling the wire rods have three possibilities:

• Can be stored and sold as black wire rods;

• Can be annealed in an electric furnace, pickling, stored and sold as annealed and pickled wire rods;

• Can be cold drawn, stored and sold as drawn wire.
