The roughing mill is made up of six independent rolling mill stands, the last four of which incorporate small vertical rolling mills called edgers. Slabs heated in the furnace until they glow bright orange-yellow are rolled through one stand at a time to produce so-called transfer bars suitable for finish rolling. High-pressure water-jet

Using the values for inside diameter of the raceway and the outside diameter of the individual conductor from the example, you get the following value: 1.05 x (D ÷ d) 1.05 x (5.07 in. ÷ 1.60 in.) = 3.33. Because this calculation results in a number greater than 3.0, you probably won't have a jamming problem. Conductors need headroom, too
