From the measurements of work roll temperature in a roughing mill, Stevens et. ) estimated that the heat transfer coefficient (HTC) within the roll bite (zone 1 in Fig. 1) was /(m2 K) during the first 30ms in the arc of contact and 18kW/(m2 K) thereafter. These values of HTCs were used for the roll bite zone in the present model ...

In flat steel rolling, roughing mills are used to roll slabs into thin plates within 5 to 7 consecutive reversing rolling passes with decreasing thickness. Some of these mills are equipped with edger rolls to control also the width of the plate. Edger rolls are usually mounted upstream of the roll gap.

Keep a low cut width (or cut depth if you're talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 23x chip load will be right for the finish pass.

The first mill of the steel slab goes through is the roughing mill. After the roughing mill, the slab's temperature between 1050℃ and 117℃, and the slabs should be called transfer bars. Then, the transfer bar goes through another few more procedures. Among all these processes, the most important two processes are finishing mills and cooling.
