The main rolling mill of the automatic plug mill is the two-high irreversible longitudinal rolling mill. Behind the working roll, there is a rolling mill equipped with a pair of reverse rolls rotating at high speed reversely. The rolled pipe is delivered back to the front stage automatically by reverse rolls.

The roll rotates to pull and simultaneously squeeze the strip between them. The strip is rolled in several passes either in a reversing mill or in a tandem mill. Each work roll is supported by a backup roll of larger diameter. As the strip passes through the pairs of work rolls in each pass, the thickness is successively reduced.
