Product Description:

Metal-rolling Mill Rolls

As a major manufacturing country, China accounts for 70% of the global production of rolls. In recent years, the trend in steel products in China has been: declining demand for construction steels such as rebar, wire rods, and narrow strips used in traditional construction, while there is a rapid increase in demand for plate and strip steels and section steels used in new infrastructure, new energy, and shipbuilding industries.

Hot Strip and Plate Metal Mill Rolls

Hot plate/sheet mill rolls and strip/coil mill rolls are vital components in the steel manufacturing process, particularly in the production of flat steel products such as sheets, plates, strips, and coils. These rolls are used in rolling mills to shape and reduce the thickness of steel slabs and ingots into various forms such as sheets, plates, strips and coils.
