Appeal No. 2003-0764
Application No. 09/660,797
APPENDIX
1. A method of cooling a steel section from rolling heat,
wherein the section has different section parts of different masses
located at a distance from each other over a cross-section of the
section, the method comprising initially determining and computing
heat quantities to be proportionally removed from the different
section parts in dependence on the masses and temperatures thereof
and a quantity of cooling medium required for removing the heat by
using measuring equipment together with a computing unit by means
of a computer program, and subsequently carrying out cooling of the
different section parts in a controlled manner such that the
different section parts reach with as little time delay as possible
the transformation line Ar3/Ar1 during the decomposition of the
gamma-mixed crystal into ferrite and/or pearlite while releasing
the transformation heat.
