As previously mentioned, it has been generally acknowledged that in the industry and the Traditional Textbooks that for the leader pass type, the pass axial ratio can not be too little, with the normal operation that guarantees each equipment and final compact dimensions.
For example, Zhao Songjun, Tang Wenlin " Pass design " (Beijing: metallurgical industry publishing house,, the 321st page in 2005) of writing is mentioned:
" the non-axial section pass design universal process that waits.After axis hole type design finishes, non-pass such as axial section such as grade in the middle of next will design.Method for designing adopts known two passes such as axial section such as grade to ask the middle non-method that waits the axial section pass, hereinafter to be referred as the design of flat hole.The design of flat hole has again two kinds of situations, and one is flat hole of folder between two types such as axis hole such as grade, and namely twice shut out one and wait axial section; Another is two flat holes such as folder such as two axial sections such as grade, and namely three roads shut out one and wait axial section.
The target of flat hole design is: obtain a flat rolled piece, make it rolling in next pass after, obtain waiting the axial section rolled piece; To the fixed rotating speed tandem mill, also require each frame heap of assurance to establish unprincipled connection, should guarantee workpiece measurement, guarantee again to pile and establish unprincipled connection, the target of pursuit is not unique.Sometimes also to consider the axial ratio in flat hole, when flat hole axial ratio greater than 2.8 the time, reduce axial ratio as far as possible.And when axial ratio less than 2 the time, then should strengthen axial ratio as far as possible.”
(the 107th page) further mentioned in this book:
" the design of B leading oval pass
