摘要

1. A roller mill for pilger rolling of a hot rolled seamless pipes of 610 × 28-32 28 × and 630 × 32 mm for pipes reheat steam boiler plants of the sleeves and the hollow ingot electroslag remelting size 690hvn.590 3300-3500 ×, × 700hvn.580 3200 ± 50 and 3200 ± 720hvn.600 × 50 mm comprising circumferentially barrel diameter 1045 mm working and idle portions, a length of respectively 210 and 150 °, the working portion includes circular section groove with transverse tangential outlets, the length of which is composed of successively located Boyko a, a length from 0.47 to 0.48 of the total length of the working part with an angle transverse release, changing the length of the striker from 32-37 ° to 20-25 ° in a transition section for a polishing portion, whose cross section is formed depending on the reducing changing the roll crown radius by an amount of 160 to 170 mm, the polishing portion extending from 0.33 to 0.34, whose cross section is formed gradually decreasing to half of the calculated value of the profile of the finished tube, longitudinal discharge angle, a length of from 0.19 to 0, 20, the cross section cat increasing orogo performed depending on the change of the radii of the longitudinal angle of release, characterized in that the roll barrel is made 1150 mm diameter and comprises circumferentially working and idle portions with central angles of 220 ° and 140 ° .2. The roller according to claim 1, characterized in that the striker is from 0.36 to 0.37, the polishing portion from 0.45 to 0.46, and the angle of the longitudinal manufacture from 0.18 to 0.19 of the total length of the working portion of the roll .3. The roller according to claim 1, characterized in that the anvil roller having a central angle of 80 °, a common compression-pressure reduction sleeves and the hollow-ingot Zago
