According to the deformation principle of rolled parts, steel rolling is generally divided into the following three forms:
*.1 Longitudinal rolling: the running direction (axis) of the rolled piece is perpendicular to the axis of the roll, and the rolled piece moves in a straight line; production of steel sections, plates, and continuous rolling of seamless steel pipes (one rolled piece is rolled on two or more rollers at the same time) Rolling in pass type or stand is called continuous rolling) etc. all belong to longitudinal rolling.
*.2 Cross rolling: The running direction (axis) of the rolled piece is parallel to the axis of the roll, and the rolled piece makes a rotary motion; the production of motorcycle hubs, bicycle axles, etc. belongs to cross rolling.
*.3 Cross rolling: The running direction (axis) of the rolled piece is neither perpendicular nor parallel to the axis of the roll. In addition to the forward motion, the rolled piece also rotates its own axis and makes a spiral forward motion; the most common seamless steel pipe The production of piercing (except push piercing and extrusion piercing) is cross-rolling; the three sets of ASSEL rolled pipes are also cross-rolled.
