Description

Technical Field

[0001] The invention relates to the technical field of roller defect elimination, in particular to a device for eliminating surface defects of a finished roller product. Background Art

[0002] Roller: Rollers used for cold rolling are generally flat rolls, which are used to roll plates and strips. In a broad sense, cold rolling rolls include working rolls that are in contact with the rolled product and backup rolls that support it. Since backup rolls are a self-contained system, cold rolling rolls are often referred to as cold rolling working rolls in a narrow sense. Cold rolling rolls must have sufficient strength, uniform high hardness and surface quality to withstand extremely high rolling forces, ensure sufficient wear resistance, and meet the requirements for rolled product precision. Forged steel rolls that can be quenched to a high hardness are used as cold rolling rolls.

[0003] The structure of an existing device for eliminating surface defects of finished rolling mill rolls is relatively simple. Currently, most devices for eliminating surface defects of rolling mill rolls directly use bolts and nuts to fix the rolling mill rolls when inspecting the rolling mill rolls. As the inspection time of the rolling mill rolls goes by, the bolts and nuts may become loose, causing them to fall off and cause safety accidents. At the same time, when the equipment detects defects, it will not mark them, resulting in the staff being unable to find the defects in the first time when performing subsequent maintenance.
