SUMMARY

The power required to forge a 100 mm diameter, 50 mm tall low-carbon steel cylinder at 1200°C, reducing its height to 15 mm with a constant flow stress of 80 MPa, can be calculated using the formula: Power = Force x Velocity. Given the efficiency of 60%, the necessary calculations involve determining the forging force based on the cylinder's dimensions and material properties. The final power output will be adjusted to account for the efficiency factor.

PREREQUISITES
  • Understanding of mechanical metallurgy principles
  • Familiarity with flow stress concepts in materials
  • Knowledge of power calculations in mechanical systems
  • Basic proficiency in using equations related to force and velocity
NEXT STEPS
  • Study the equations for calculating forging force in cylindrical shapes

Hi, can anyone help me on the following problem? Thanks a lot in advance!

A 100 mm diameter, low-carbon steel cylinder, 50 mm tall, is forged at
1200°C at a velocity of 1m/s until its height is reduced to 15 mm.
During forging it is assumed that the flow stress is constant at 80 MPa.
Assuming an efficiency of 60% determine the power required to forge
the cylinder.

I do not know what equations to use. I do not have many references (books or website) to look at. I never learned mechanical metallurgy before and this is my first year in graduate school. in a panic...

I know force times velocity is power. I would assume that this is what you need to use.

EDIT: oops didn't realize how old this thread was.
