Abstract：The Fe-based high alloy material, represented by spun cast work rolls for hot rolled strips, is one of the most
widely used and most mature large-scale industrial products in the tool steel fields in terms of the manufacturing and their
applications. The R&D (research and development) and manufacture of these types of rolls in China have made a leap
forward accompanied along with the rapid development of the Chinese steel industry. The diversity of roll materials and
specifications, as well as product reliability, performance and manufacturing capability have been continuously improved.
The revolutionary development of new material research technologies, such as integrated computing material engineering
(ICME) as, and acceleration of the intelligent development trend of manufacturing, greatly assists the R&D and processing
of roll products. This paper mainly introduces the development history of hot strip mill work rolls and the market demand
for new types of products. The development of roll material and the intelligent manufacturing of the roll products are
briefly described, and the development trends of roll manufacturing industry are also slightly discussed.
