Steel Pipe Cold Rolling MachineCold rolling machine is periodical rolling mill, the work frame and mill rolls do reciprocating motion under the drive of crank-link mechanism. The mother tube makes deformation under action of dies and mandrel and gets high precision finished tube.Advantages of Cold Rolling Process ·Large cross section reduction, decrease intermediate process;·No process-related material losses;·Better mechanical properties and physical properties;·Produce thin and ultrathin wall thickness pipes and tubes;·No scratches on both outer and inner surface;·Possible to roll high alloy
