engineering recuitment GATE ME 2023-24 Test Series Production Engineering (Manufacturing) Metal Forming Rolling
A rectangular section, 120 mm wide and 60 mm thick is rolled to some thickness by passing it through rolls of diameter 450 mm. If the coefficient of friction is 0.4 then
1
Highest possible reduction per pass is 36 mm
2
Length of contact is 85.61 mm
3
If rolling pressure is 450 MPa, then the rolling load is 5401 kN
4
No. of passes if final thickness = 24 mm, is 1
