Causes and control measures of edge drum defects in cold rolled steel strip
The edge drum of steel coil is mainly due to the irregular cross section shape of hot rolled steel coil, that is, the local high point, resulting in the defects of bulging or strip-like protrusion of cold rolled steel strip at the high point.
Where did the strip go?
Since I entered the line in 2017, I often heard many people (traders, downstream factories) sigh: Where did this strip steel (hot rolled strip, hereinafter referred to as strip steel) go? With so much production every day, steel mills have no shortage of sales. They all say that the strip steel is not useful, and they are sold out, even at the market price. Some salesmen also often complain about how hard to sell strip steel, but want to sell when the goods are sold, whether it is for the market or for downstream customers.
