The wire surface has different shapes of rupture called cracks, divided into longitudinal cracks and transverse cracks. General longitudinal cracks in the wire surface is continuous or intermittent distribution; and transverse cracks are discontinuous distribution. Some cracks have inclusions and decarburisation on both sides. Causes of forming crack 1 Billet used…
The surface of the wire along the rolling direction is straight or jagged unwelded gap, in the cross-section presents folding defects called folding, generally along the rolling direction is continuous or intermittent distribution. Folded sides are often accompanied by decarburisation layer or part of the decarburisation layer, folding seam in…
On the surface of the wire and the body of the adhesion of a head or completely non-adhesive metal layer called scarring. Generally it is tongue-shaped, uneven thickness and size. Some scars are rooted, some not rooted, in the full length of the wire, regular or irregular distribution. Scars will impact on the wire surface…
Wire surface parallel to the direction of the extended rolling bar raised called lugs, was continuous or intermittent distribution. On one side of the wire called unilateral lugs; on both sides of the wire called bilateral lugs; wire up and down the two semicircular staggered called wrong side lugs. Mainly…

VD furnace is mainly used to refine steel liquid via vacuum degassing treatment, to precisely and finely adjust the component of steel liquid in order to meet the production requirement of special steel and high-quality steel. Through the treatment of VD furnace, the hydrogen content of steel liquid can be…
