Analysis and Research of Single Rack Four Roller Hot Rolling Mill

High-precision aluminum foil and foil products require high-quality hot-rolled coil blanks. The production process is semi-continuous casting, hot rolling, cold rolling, and finishing. The ingot is opened and processed into cold-rolled billets (ie, hot-rolled). The coil is finished by a hot rolling mill.

There are many types of hot rolling mills, including single-stand, two-roll hot rolling mills, two-stand four-roll hot rolling mills, and multi-stand hot rolling mills.

The former has a small roll weight, does not adapt to the requirements of modern cold rolling mills, has poor control accuracy, low speed, narrow product variety, but has low investment; the latter two have large production scales, high control precision, large volumes, and wide product coverage. Satisfy all the requirements of the production of aluminum foil and foil products, but the investment is large, the construction period is long, and it is difficult for general enterprises to bear.

Compared with the above-mentioned hot rolling mills, the single-stand double coiling hot-rolling mill has the features of high equipment level, high product precision, appropriate production scale, relatively low investment, wide variety of product coverage, and a roll weight of up to 7 tons. It is suitable for the requirements of modern cold rolling mills owned by domestic aluminum processing companies.

Research and development of a single-stand double-rolling four-high hot-rolling unit to provide high-quality, inexpensive equipment to the aluminum foil processing plant. At the same time, the aluminum foil and foil processing plant will use this as a basis for the production of high-precision aluminum strip box products to replace imports. To meet the needs of national economic development. This will have very important significance in promoting the development of China's aluminum processing industry and stimulating the development of related industries.
