(2) Casting, sanding, venting, hard spots, etc. may occur due to problems such as operation, material, and alloy composition. Defects make the processing process difficult
(3) The partially repaired rolls also need to be turned and have high hardness. Unevenness and uneven hardness are also difficult to process
