Question

Calculate the bite angle when rolling plates 12 mm thick using work rolls 600 mm diameter and reducing the thickness by 3mm
5.73

Open in App

Solution

The correct option is A 5.73
$B i t e a n g l e : θ = t a n^{- 1} ⎛ ⎜ ⎜ ⎜ ⎝ \frac{\sqrt{R Δ h}}{R - \frac{Δ h}{2}} ⎞ ⎟ ⎟ ⎟ ⎠$

$H e r e, Δ h = 3 m m, R = 300 m m$

$θ = t a n^{- 1} (\frac{\sqrt{300 \times 3}}{300 - 1.5}) = {5.73}^{\circ}$

Q. In a rolling operation using rolls of diameter 500 mm if a 25 mm thick plate cannot be reduced to less than 20 mm in one pass, the coefficient of friction between the roll and the plate is

Q. The thickness of a sheet is reduced by rolling (without any change in width) using 600 mm diameter rolls. Neglect elastic deflection of the rolls and assume that the coefficient of friction at the roll-workpiece interface is 0.05. The sheet enters the rotating rolls unaided. If the initial sheet thickness is 2 mm, the minimum possible final thickness that can be produced by this process in a single pass is mm(round off to two decimal places).
