1.	In a slab rolling operation, the maximum thickness reduction (Δhmax) is given by Δhmax=μ2R, where R is the radius of the roll and μ is the coefficient of friction between the roll and the sheet. If μ=0.1, the maximum angle subtended by the deformation zone at the centre of the roll (bite angle in degree) is____.5.73
Answer» In a slab rolling operation, the maximum thickness reduction $(Δ h_{m a x})$ is given by $Δ h_{m a x} = μ^{2} R,$ where R is the radius of the roll and $μ$ is the coefficient of friction between the roll and the sheet. If $μ = 0.1$ , the maximum angle subtended by the deformation zone at the centre of the roll (bite angle in degree) is____. 5.73
