Abstract：Zirconium alloy has properties of large deformation resistance,poor mobility,and strong viscosity. It leads strict requirements of extrusion ratio,mold shape,extrusion speed,heating temperature,and lubrication process.A 40 MN double-action zirconium extrusion is used to produce a grade of nuclear zirconium.Special lubricant is used for coating lubrication,heating temperature deviation of billet is controlled in about 30℃, holding time is controlled in about 10 min,reaming extrusion is selected,reaming speed is 5 ~10 mm/s,and extrusion speed is 5 ~10 mm/s.Precise result can be obtained in zirconium alloy extruding.
