Green Low-carbon Advanced Technology- Rotary kiln pelletizing flue gas processing

Ultra-low emission technology of flue gas for chain grate machine and rotary kiln pelletizing is one of the national green low-carbon advanced technology achievements, applicable to the flue gas treatment in the process of rotary kiln pellet production. This technology utilizes selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR)…

Steel Mill Robots

More and more industrial robots appear in production area of the steel plant, robots can work continuously for a long time, and there is good consistency of the work standard. 1.To replace the labour-intensive jobs. For repetitive, and labour-intensive operations, robotic operations can reduce the labour intensity and risk of…

Wire Surface Defects – Crack

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…

Wire Surface Defects – Folding

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…

Wire Surface Defect – Scarring

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 Defects – Lugs

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…
