AUTOMATIC UNITS TO MONITOR ROLLING-MILL ROLLS DURING SERVICE

摘要

The technical-economic indices of rolled-product manufacturing depend to a large extent on the quality of the rolls that are used. This means that the condition of the rolls must be checked while they are in use. However, most rolls are subjected only to visual inspection and/or manual ultrasonic inpection during service. The problem is complicated by the fact that there is currently no single standard that governs the inspection of rolling-mill rolls by nondestructive methods. Such a standard should include well-substantiated rules on the acceptability of different defects and should differentiate them based on type and location (internal or external).
