In a four high rolling mill, there are four rolls out of which Two are working rolls and two are backing up rolls.
In a four high rolling mill, there are four rolls out of which Two are working rolls and two are backing up rolls.
In a four high rolling mill, the diameter of backing up rolls is Larger than the diameter of working rolls.
The parts of circular cross-section which are symmetrical about the axis of rotation are made by Hot spinning.
The stress in the flange region during the deep drawing process is a combination of radial tensile drawing stress and a tangential compressive stress.
The blank-holder at the top of the workpiece exerts a compressive force at the upper surface of the blank during the drawing process.
The mode of deformation of the metal during spinning is Bending and stretching.
