Carbon Steel Wire Rods For Structural Stee, Tube and Hollow Sections
Long / Wire Rod
At the Wire rod rolling mill, which is one of the most critical points in the transformation of ore into steel, the process begins with the precisely alloyed liquid steel being turned into billets using the open and closed casting technique at the continuous castings plant.

Long / Billet
At İsdemir, billet production is carried out in a wide range of different steel qualities. Precise chemical composition adjustment and low steel pollution can be achieved with the BOF production process from ore using the continuous casting technique. Billets are cast with stopper-controlled immersion nozzle technology in the continuous casting facility. With the help of nozzles used in closed casting, casting of liquid steel is ensured without contact with air. In addition, center line segregation is minimized with the electromagnetic stirrer and oscillation method in our casting machines.
