Seamless steel tube mill classification
Capillary rolling is the main deformation process of seamless steel tube.Its function is to make the wall thickness of the capillary close to or reach the thickness of the finished pipe wall, and eliminate the non-uniform wall thickness of the capillary in the perforation process.The surface quality of the internal and external parts of the waste pipe is controlled, and the outer diameter and roundness of the waste pipe are controlled. The hollow capillary is rolled into a waste pipe near the final size. 1, double roll mill: continuous rolling mill is a more advanced steel tube rolling mill. It puts the porous capillary on the long mandrel, which is arranged on a number of frames in turn, and the joint of the adjacent frame roll is 90 degrees. The continuous pipe mill is rolled. The main material of the continuous roll is Ni Cr Mo infinite cold hard ductile iron (also known as Pearlite Nodular Cast Iron), nickel molybdenum infinite cold hard ductile iron (also called acicular nod...
