Question

15.43 A planned extrusion operation involves steel at 1000° C with an initial diameter of 100 mm and a final diam- eter of 25 mm. Two presses, one with capacity of 20 MN

Answer 1

Solution: iveo Data- Temperature = /o00c Cor o. m DO mm Initial diameter (d;)- diameter de) = 25 mm (or) 0.02 S M Final capacity capacity is 20 MN 0 MN 2 - Initial area (A:) = Uxd; / -2 7.S5 Xlom Fihal Area Ap) Tx(.02 my 4 steel at l000c the Constant for extrusion Can We assame be 425 mPa tr Constant (k) eztyusion 42S mPa Extrusien Ferce F)= ApK in/AL X 425 Lh 785 xlo 4.910 9.2475 MN Thus, the smaller and easier is not Suitable use Press opeabian this but it almast fur have Sufficient capacity.
