Description
ме того, при дальнейшей раскатке труб с бунтами , расположенными по спирали, на станах поперечно-винтовой прокатки отсутствует биение трубы в очаге деформации, так как бунты не выход т за пределы контактной поверхности металл-валок, что приводит к уменьшению разностенности.Moreover, during further rolling of pipes with riots arranged in a spiral, there is no beating of the pipe in the helical rolling mills of the pipe in the deformation zone, because the riots do not extend beyond the metal-roll contact surface, which leads to a decrease in thickness.
Наличие кольцевых выемок с профилем несимметричной формы на калибре валка позвол ет в процессе производства труб сократить количество операций и уменьшить разностенность труб.The presence of annular grooves with an asymmetrical profile on the roll caliber allows, during the production of pipes, to reduce the number of operations and reduce the spacing of the pipes.
