(a) Define the following terms in rolling:
(i) bite angle (ii) percentage reduction in thickness
(iii) elongation coefficient (iv) neutral point
(v) forward slip
A slab of 300 mm initial thickness, 600 mm wide is given a reduction of 50 mm in a rolling mill with rolls 1000 mm diameter. The spread in this pass is 5 mm. Calculate the values of the bite angle, percentage reduction in thickness and elongation coefficient.
How is forward slip determined experimentally?
