Minimizing wall thickness variation in seamless tubing

Overview of the Three Process Steps.Seamless tube manufacturing usually starts with hot cross-rolling in a piercer mill.Piercing is the first process step to make tube with a high-quality wall.This step usually is followed by one or more elongation processes that can improve wall quality while also increasing tube length.Making seamless tubing with a floating mandrel millThe process cross rolls the preheated billet between two barrel-shaped rolls at a high speed.The cross rolling causes high tensile stresses at the center of the billet.The design of the piercer rolls causes the metal to flow along the roll and over a piercer point as it exits the process.The piercer point is a high-temperature,water-cooled alloy tool designed to allow the metal to flow over it as a tubeLoad-bearing structure for a continuous rolling mill for In the drawing figures,there is shown a load-bearing structure for a continuous rolling mill,according to the invention,which comprises three pairs of working rolls 2-3,4-5,and 6-7,and their respective chocks 8 to 13,for making a seamless tube from axially bored
