Cold rolled steel with common problem analysis

Tin pack is processing of cold-rolled steel belt. The quality of cold rolled steel belt determines the quality of the iron straps. Analysis of cold rolling with the source of the common problem now. First of all, is the time when the material itself is flawed, but this kind of defect in cold rolled operation, also can't remove, one of the most common defects should be holes; Second cold rolling process due to the deformation caused by the defect of the basic it is because the operator in the process of operation, caused by improper operation, but there will be a certain periodicity, such as vibration mark and roller printing, etc. ; The defect of cold rolled strip steel corrosion in again, mainly because of the outside environment of strip steel surface chemical reaction, cause its surface appears serious corrosion, such as common rusty spot, etc. Processing machinery. Damage caused by defects in production and processing of cold-rolled strip steel, it is in touch with the hard, lead to strip surface defects;
