A high chromium (HiCr) iron work roll broke in three pieces in finishing stand 4 in a compact strip production (CSP) mill of a steel company. This roll breakage was examined by means of visual inspection, analysis of the mill process data, and chemical and microscopic analysis of a sample from the spheroidal graphite (SG) iron roll core.
The following chart is Recommended Surface Footage for standard 4Flute styled endmills. For aluminums, start somewhere in the middle. For steels start on the bottom side and work your way up. Always use manufacturers recommended Surface Footage for tooling where applicable.
the hot strip mill after grinding are free from surface breaking cracks and internal defects that may cause roll failure during service. Hot strip mills in finishing stands normally utilize cast duplex type work rolls in alloy indefinite chill double poured (ICDP) or high chrome iron grades

Cast iron shells require special treatment due to the formation of a graphite layer on the iron during acid cleaning. However, there are processes using molten caustic salts which can be used to prepare the surface for bonding. Of major importance to successful bearings is thorough physical and chemical cleaning of the shell before bonding. A ...
