Cast high speed steel roll: a major achievement in the development of roll in the world.

At the end of the 20th century, the rise of cast high speed steel rolls has become an important event in the history of world roll development, because it has crossed the high chromium cast iron and high chromium steel rolls we are developing at a very fast speed, and has quickly occupied most of the market. For many years, generations of roller manufacturers have tried to make the carbide in the roll tissue into a dispersed and isolated form. The successful development of high-speed steel rollers has made this dream come to pass, and has changed the traditional Fe3C (M3C) and M7C3 carbides into MCM2C and M6C carbides with better performance, greatly improving the comprehensive performance of the roll working layer. 

When we exclaim the rapid development of international roll manufacturing technology, we have been pulled apart by foreign countries. All the men of insight in the domestic roll industry must face up to this reality and concentrate the financial, material and manpower resources to develop the casting high speed steel rolls needed by modern rolling mills.
