METHOD OF EVALUATING PERFORMANCE OF WORK ROLL

摘要

The method for evaluating work roll performance according to one aspect is to have an effective diameter as a diameter obtained by subtracting the discard diameter, which is the diameter in the finished state, from the initial diameter, which is the initial diameter of the work roll, from the specimen collected from the processing allowance of the body for manufacturing the work roll. Performing an abrasion test on a test piece made in a disc shape in a high-temperature wear-resistant tester, calculating the wear amount of the test piece, measuring the wear profile and roughness of the test piece, and the wear amount, wear profile and surface of the test piece It includes the step of evaluating the performance of the work roll using the roughness.
