number of exit stand (must be > 0)? <8>
----------

GENERAL INPUT DATA

d (roll barrel diameter, mm) and gap (nominal roll gap, mm)
HSC (roll surface hardness, Shore C) - approx range 40 to 120
KSC (roll surface material)
spd (bar speed out of single pass, m/s) [*]
temp (rolling temperature, ºC) - range 800 to 1200

values of KSC are:
   0 (Non-graphitic steel); 0.5 (Graphitic steel);
   1 (Nodular pearlitic cast iron); 1.5 (Nodular acicular cast iron);
   2 (Nodular martensitic cast iron); 2.5 (Chilled cast iron);
   3 (IC cast iron); 3.5 (Hi-Chrome cast iron); 4 (Tungsten carbide).

[*] Continuous-linked stands only require stand 8 exit speed
    to be specified.

     - i for independent stands
     - c for continuous-linked stands
     - m to return to menu

Now you must choose the intermediate pass: oval or diamond?

The choice depends on lamk: if current lamk is greater than upper limit
UL, choose an oval; if lesser than lower limit LL, choose a diamond.

If lamk is between limits (LL < lamk < UL), modify square bar
(or square pass) dimensions to the nearest limit.

The current situation is as follows:

- entry square:         40      8       90
- exit square:          30      6       92

- UL = 1.778257
- LL = 1.702698
- lamk = 1.789437       You should use an
                        OVAL
