rolling mill

There are two - high, four - high and multi - high rolling mills for cold strip rolling. The most widely used is the four-high mill. Thinner products are rolled with a multi-roll mill. There are many kinds of multi-high rolling mill, such as six-high rolling mill, off-eight high rolling mill, twelve high rolling mill, twenty high rolling mill, etc. (see Rolling mill). With the improvement of flatness requirement, many technologies have been developed to improve flatness, such as bending roll technology, channeling roll technology and cross roll technology. Cold strip rolling mill can be divided into two types according to stand arrangement: single reversible or irreversible and multi - continuous. The former is suitable for many varieties, less batch or large proportion of alloy steel products. It has low investment and fast plant construction, but low output and high metal consumption. Multi-stand continuous rolling is suitable for the product variety is relatively single or little change, it has the advantages of high production efficiency, large output, but the investment is larger.
