Measuring the hardness of roll by what way?
2013/12/5??????view:
The hardness of roll manufacture and use is an important indicator of quality. Hardness testing the detection method using Rockwell hardness and Vivtorinox, which belongs to the indentation test method of hardness, is characterized by good stability, usually for a small easy implementation of Rockwell hardness testing andVivtorinox. But for the large forged steel rolls, artifacts due to large volume, lifting and mounting difficulties, so it is widely used for Shaw and hardness test. China has promulgated the roll of Shaw's national standards, hardness test and a corresponding provision.
