Ferro silicon magnesium cored wire is widely used on ladle refining process. Crushing the additives (de-oxidant, desulfurizer, alloys) into certain granulation (in the form of powder), then, using the equipment to fill the powder into “U” shaped sheath, which is made of high quality cold rolled steel strip, lastly, tightly closing the wire, so a multiple material (cored wire) with certain length will be obtained.
