Description
Известен способ продольной прокатк труб в двух последовательно расположенных клет х на короткой оправке в валках с круглым калибром. При этом величина обжати стенки ограничиваетс степенью предварительного редуцировани гильзы трубы по диаметру.The known method of longitudinal rolling tubes in two successive cells on a short mandrel in rolls with a round caliber. In this case, the amount of wall reduction is limited by the degree of pre-reduction of the tube sleeve in diameter.
С целью увеличени обжати стенки трубы н улучшени условий захвата гильзы валками , гильзу перед клетью обж-имают относительно вертикальной оси задающими роликами .In order to increase the reduction of the pipe wall and improve the conditions of the seizure of the liner by the rollers, the liner in front of the stand is pressed against the vertical axis by the guide rollers.
Способ заключаетс в том, что задающи.ми роликами, установленными перед клетью, обжимают гильзу без оправки в направлении,The method consists in that by setting the rollers mounted in front of the cage, they press out the sleeve without the mandrel in the direction
