How pass line is calculated in hot rolling mill?

Pass design for channel section in rolling mill? All depends on the channel size, 7 or 9 passes required to reduce from a rectangular or square starting section.


Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest - also, maybe later. K. H. Schröder K. H

Mill Steel Charge Volume Calculation

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or ...

Load Analysis and Driven Power Calculation (Symmetrical …

Therefore, the calculation of the force analysis and driving power of the plate rolling machine is very important to the design of the roll bending machine. In this post, the calculation of the force capabilities of symmetrical three-roll bending machine is one of the methods, the other types of plate rolling machine can take it for reference.
