steel strip slitting

What are the abnormal phenomena in slitting production. Let's to concrete analysis, so that everyone has cognition to the problem, the content is as follows.

Anomaly: bad product volume

Volume: collapse was caused by a lack of tension or in the handling process of sinosteel volume rendering elliptic, that cause certain difficulty to the next working procedure, should be appropriate increase the tension.

Bad side, crease: in separated extrusion or raw material cutting edge will cut off the damaged parts, the winding when the product's injury caused by tension and deformation. Solution is at the edge of the shear bad way, attention to pay attention to the presence of not finishing the bad side of, before they can enter the take-up device for smooth processing.

Surface anomalies. 2: the poor

Scoliosis: also called sickle bending, refers to the lateral bending steel strip after cutting, for many reasons, such as raw materials did not completely eliminate internal stress, uneven uneven blade gap, burrs, unequal, lateral thrust should be according to the specific reasons for analysis and solution of concrete is not detailed here.

Anomaly 3: at a discount

Refers to the strip appeared continuity crease, causes include the blade used synthetic outer diameter is too small, drum circle, or severe jaw protrusions, etc.

The solution has a try to choose the return of synthetic material, etc., using large diameter attention to under the condition of does not produce the knife.

Anomalies four: creasing embossing

Raw materials or strip when hoists from or rewinding, is impacted by the lumps or extrusion forming local tensile deformation. If because of the raw material or strip when lifting, horizontal plane and form of a massive bump impact on material, that requires attention when lifting location of level off, the best completes the protective measures; If it is caused by a foreign body on the blade, a foreign body that will require at any time pay attention to whether the blade adhesion, cutting tool should be wiped clean before operation.

Five: anomaly wrinkled skin

Refers to the material you have soft foreign bodies involved in coiling, or the formation of excessive tensile deformation on both sides of the strip tension causes buckling wave sample center. For the former, the solution is to prevent foreign body involved in or prevent cushion block off in rewinding tension materials; For the latter case, the fundamental reason is the guide wheel worn edges on both sides, the both sides and center tension uneven tensile deformation, the solution is to guide rotation detection and repair on a regular basis.

Anomalies six: surface grinding scratches

Refers to the material surface and the friction between external things, thus cause poor material surface mechanical damage, might have been caused by raw material relaxation, may also be caused by a foreign body, the solution is often clean the tension pad, soft liner materials as tension.
