Introducing Cold Pilger Mill Technology - Tube and Pipe Production - Scribd

The cold pilgering process is suitable for all metals. Typical materials are mild steel, stainless steel, ferritic steel, low-alloy steel, copper and copper alloys, titanium alloys, zirconium alloys, and nickel alloys (see Figure 4). Using cold pilgering to reduce precious metals is conceivable, because practically no material loss occurs.

FINITE ELEMENT MODELLING OF COLD PILGERING OF TUBES

mechanical FE model of the cold pilgering process is developed. The Johnson-Cook model is used to describe the flow stress accounting for temperature, strain rate and strain path dependency. 2 BACKGROUND The estimation of roll separation force is required for pilger mill design andto determine limits for tube dimensions or process parameters.

FINITE ELEMENT MODELLING OF COLD PILGERING OF TUBES

Cold pilgering is a cold forming process used to manufacture seamless tubes which for some materials enables area reductions more than 90%. During the process, the tube is compressed between a mandrel on the inside and two rolls on the outside, which are oscillating forward and backward. Before each forward and/or backward stroke, the tube is fe...
