Assel mill

Capillary rolling is the primary deformation process in the production of hot-rolled seamless steel tubes, serving to reduce the wall thickness of the capillary tube to near or equal to that of the finished tube and to eliminate longitudinal wall-thickness non-uniformity introduced during the piercing operation.

  • Product Description
  •   Capillary rolling is the primary deformation process in the production of hot-rolled seamless steel tubes, serving to reduce the wall thickness of the capillary tube to near or equal to that of the finished tube and to eliminate longitudinal wall-thickness non-uniformity introduced during the piercing operation. 
      Our company primarily manufactures Accu-Roll tube rolling mills and Assel tube rolling mills.

    The automatic pipe rolling machine is used for Thick-walled capillary tubes are rolled into thin-walled rough tubes, typically through 2 to 3 passes, until the desired finished wall thickness is achieved, with a total reduction in wall thickness of approximately 1.8 to 2.2; main

    To be used for the production of hot-rolled thin-walled seamless pipes,  
    The Accu-Roll tube mill features two conical rolls arranged horizontally, complemented by two large-diameter, vertically mounted drive mandrels, in conjunction with a fixed mandrel. This configuration provides a long wall-thinning zone and ensures uniform deformation, making it well suited for the production of medium- and thin-walled steel tubes.

    Assel tube rolling mills offer high dimensional accuracy, excellent surface quality, convenient roll adjustment, and low tool consumption. Used for the production of hot-rolled medium- and thick-walled seamless pipes.
    Various rolling mills capable of producing pipes with diameters ranging from φ70 to φ377 mm are available.
