Understanding Rolling Process in Long Product Rolling Mill ...
Since cross-sectional area is reduced progressively at each set of rolls, the stock moves at different speeds at each stage of the rolling mill. A wire rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a finished rod (as small as 5.0 mm in diameter, 1 ...

Example: If a bottom roll had an original throat diameter of 4.500", and was reworked to 4.250", you would subtract the smaller diameter from the larger diameter, where in this case would be .250". You would then divide .250" by two (2), which would be a .125" thick shim to be placed under the bottom bearing block of this reworked pass.
