Does the equatorial line pass through India?
No. Only the Tropic of Cancer passes through India.
The southernmost point in India (the city of Nagercoil) is 8° north of the equator.
The pass line is a line that runs parallel through the roll partings and passes through the centre of the stock area of each pass at every stand. This line starts through the centre of the billet standing on the furnace exit rollrs and runs parallel through each stand through a centre line of the shear blades of the dividing shear prior to the cooling bed. All guiding equipment is aligned to the pass line.
