In order to further increase the service life of rotating parts such as bearings, Sanyo Special Steel has developed the super-clean steel production process "SUPR (Sanyo Ultra Refining Process: Sanyo Ultra Refining Process)." The inclusions in the steel produced by SUPR have fewer inclusions and a smaller diameter than traditional steel, which improves the level of cleanliness.
At present, various parts of high-speed railways, wind turbines, and industrial machinery are developing in the direction of small and lightweight. The ultra-clean steel developed by Sanyang Special Steel can meet the high design freedom and maintenance-free of rotating parts in these equipment. Claim.
The newly developed SUPR process further develops the traditional inclusion reduction and diameter reduction process SNRP. During the development of the SUPR process, the relationship between the SNRP process conditions and inclusions was studied. On the basis of SNRP, inclusion composition control technology was added to reduce the frequency of inclusions in steel.
