Embodiment Construction
[0034] Below in conjunction with the present invention is further described;
[0035] A processing technology of a pockmarked roller, characterized in that the processing steps are as follows: Roll body processing—roll neck processing—
[0036] Shaft head processing - roll neck and shaft head assembly - pitted roll assembly.
[0037] Described roll body processing comprises the following steps to form,
[0038] 1) According to the requirements of the design drawing of the pipe body, the mold is designed and made of 25CrMo or 35CrMo mold steel;
[0039] 2) Mold inspection Check inner hole size, roughness, coaxiality, roundness, straightness, wall thickness;
[0040] 3) Casting adopts centrifugal casting method;
[0041] 4) Capillary inspection Check the bayberry particles and straightness on the roll surface, and mark the length of the roll body with cutting marks;
[0042] 5) Machining clamps the large outer circle, corrects the outer circle, turning plane, stop φ325H7, be...
