Why cold rolling with the drum?

Steel belt according to the different treatment process can be divided into heat treatment steel strip and cold treatment steel strip, cold treatment of the strip is what we call the cold rolling belt. Cold-rolled steel belt on the major objects of bundling have played a very important role, several common cold rolling with simn cold-rolled steel belt, MN cold-rolled steel belt, etc. , in each big industry has played a very important role, but cold rolling with some common problems, such as a drum, a set of steel belt once the drum, indicates the product is failed, can not be put into normal use, so why cold rolling with the drum? 'Drum' refers to the cold mill coiling process on the coil surface bulge phenomenon, macroscopic expression is in the process of cold rolled strip steel strip uplift, along with the rising of the roll diameter, the drum will be more and more obvious, the loss after uncoiling, the drum position there will be a small wave form, leading to manufacture the demotion or waste. The proportion of 'drum' as rising rolling mileage has obvious upward trend; When small strip crown, wedge, local high numerical value when the cold rolling 'drum' chances are increased. To prevent the 'drum' problem in the process of production, you need to steel belt manufacturer in production adjustments according to the design of the design parameters. For example, the optimization goal crown, optimization of rolling plan, optimize the distribution of the roller type, improve the conditions of cooling, roll management, and strengthening inspection.
