The selection of the rolling mill pass system is an important part of the rolling mill pass design.
Whether it is appropriate to select have a decisive impact to the productivity and output of rolling mills, quality, consumption index, and production process operation, so the selection of rolling mill pass design system must be strictly carried out in accordance with specific conditions.
Specific conditions for the selection of the rolling mill pass system are as follows:
1) The billet conditions should be considered: whether it is continuous casting billet or rolling billet, section geometry, size and fluctuation range, billet surface quality, steel grade, etc.
2) Equipment conditions should be considered: rolling mill layout, frame structure, unit composition, number and parameters, transmission mode, motor capacity and speed range, auxiliary equipment configuration and capacity.
3) Product conditions should be considered: product variety, specification range, dimensional accuracy, and metal performance requirements.
