abstract = "The optimal thermomechanical processing in steel
industry is difficult because of the multi constituent
and multiphase character of the commercial steels,
variety of the possible processing paths, and plant
specific equipment characteristics. This article shows
successful implementation of the genetic programming
approach for increasing the furnace conveyor speed and
consequently productivity of the heat treatment furnace
in the soft annealing process. The data (222 samples
covering 24 different steel grades) on a furnace
conveyor speed, chemical composition of steel (weight
percent of C, Cr, Mo, Ni, and V) and Brinell hardness,
before and after the soft annealing, were collected
during daily production. On the basis of the monitored
data a mathematical model for the hardness after the
soft annealing was developed by genetic programming.
According to the modeled influences on the hardness,
the higher furnace conveyor speed was attempted in
practice. The experimental results of the hardness
after the soft annealing with the increased conveyor
speed and the predictions of the mathematical model
were compared within the agreement of 3.24percent. The
genetic model was also compared and verified with
linear regression model. The productivity of the soft
annealing process increased (from the furnace conveyor
speed 3.2 m/h to 7 m/h) as a consequence of the used
computational intelligence approach.",
