Seamless Structural Steel Tube And Pipe Hot Rolling Production Line Machines

Seamless Tube Hot Rolling MachineHot rolled seamless steel tube machines are use heated round billet to make finished seamless steel tube via hot piercing, elongating, sizing and straightening. The round billet heat one time then continuous producing and achieve high precision of finished tube, it is fit for mass produce. In general, the diameter of finished tube on hot rolling line is more than 32mm, and the wall thickness is more than 3.5mm. The finished products are widely used to make structural tube, fluid tube, low and medium pressure boiler tube etc.For some high-end finished seamless tubes such as gas cylinder tubes, high pressure boiler tubes, drill tubes etc. are cold rolling or cold drawing on base of hot rolling. Mechanical Equipments of Hot Rolling Line ·Heating furnace;·Piercing machine;·A-R rolling machine;·12 stand micro-tension sizing machine;·Cooling bed;·Straighter machine;·Detecting instruments.Seamless Tube Hot Rolling Machine Structural Steel Tubing Hot Rolling Machine     Hot Rolling Production Line Design Seamless Steel Pipe and tube Hot Rolling Machinery     SS Tube Mill MachineHot Rolling ProcessMain ParameterItem Description RZJ80 RZJ114 1Technical parameterOD of billet(mm)60~11080~1802OD of finished tube (mm)55~12276~1683WT of finished tube (mm)4.5~254.5~254Main online machinePiercerLXC80LXC1145ElongatorXDY80XDY1146Sizing mill3-Roll sizing mill (275)3-Roll sizing mill (380)7Straightening machineYGJ160 9-RollYGJ180 9-Roll8Other type:  RZJ60, RZJ90, RZJ160, RZJ430, CustomizedOur ServiceMachining ToolsField ServiceContact Information
