Указанные конструкции CTaiiOB обладают cyiuocTix-iiными недостатками и не приемлемы дл  холодной прокатки труи больших диаметров из-за значительного веса перемоща оших ма-гс.Known designs for cold rolling mills;, in KOiupbix, the reciprocating movement has a complete stand instead of with ii ;; .-: ;;; i -; i and a stand or reciprocating movement yes; iau i-iiix roll with rolling bearings and roll bearers supports) fixed bed. These CTaiiOB constructions have cyiuocTix-ii deficiencies and are not acceptable for cold rolling of large diameter pipes due to the considerable weight of the bulkhead.

Рабочие валки / опираютс  на опорные валки 2, ;1ообход;1м; избежани  трени  скольжени  опорной поверхиости рабочего о неподвижную направл ющую станины. Вертикальное усилие прокатки передаетс  непосредственно от опорной поверхности рабочего залка че . рез опорный валок на стационарную направл ющую стаи,ты.The work rolls / are supported on the support rolls 2,; 1 turn; 1 m; avoid friction of the slide of the working surface of the worker on the fixed bed guide. The vertical rolling force is transmitted directly from the bearing surface of the working platform. Cut the support roller onto the stationary guide of the flock, you.

Рабочий валок выполнен в виде кольца, на одной олоа: не которого нарезан ручей, а друга  половина  вл етс  опорной поверхностью и имеет радиус наружной поверхности, равный «кат щему.The work roll is made in the form of a ring, on one piece: the stream which has not been cut, and the other half is the bearing surface and has an outer surface radius equal to "rolling."

Рабочий валок установлен на вал 3, на котором расположены также т говые подшипники 4 и синхронизирующие поворот валков комические щестерни 5. На концах одного из валов 3 устггновлены зубчатые секторы 6, наход щиес  в зацеплении с рейками, закрепленными в -манине .
