Because the KZR mill is capable of high-speed rolling with high rolling reduction, it can deliver a boost to productivity for rolling stainless steel and other hard materials. HZ Mill (Advanced Split Housing ZR Mill ) Because the housing is split into upper and lower sections, a large gap between the upper and lower work rolls can be achieved.
path which represents a high mill modulus whereas the split mill housing design has more interfaces in the stress path which reduces its mill modulus. Each of the interfaces has a friction that increases the hysteresis and this is very bad for roll gap accu-racy in split housing. Mills with split housing design need to be accurately
