The INTEG Hot Strip Mill Model (HSMM) is a PC-based off-line
model capable of predicting the thermal evolution, deformation
behavior, microstructure evolution and final mechanical
properties of steel being
processed in a hot strip mill. The user can easily set-up their
mill configuration, including number of reheat furnaces, roughing mill
stands (reversing or continuous), heat retention equipment, finishing
mill stands (tandem or Steckel), run out table cooling system and mill
exit area. The model can handle both strip and plate products. A variety
of steel grades can be modeled.
The HSMM uses a series of physical models to calculate both thermal
mechanical and microstructure evolution. The model can be run in
both single node and multiple node modes and offers a selection of
modeling methods to be utilized for flow stress calculations in the
roll bite. While calculating the final temperature run down for the
run out table and coiler or cooling bed, the ferritic grain size
and final mechanical properties including Yield Strength (YS), Tensile
Strength (TS) and elongation are determined. The microstructure model
calculates recrystallization, austenite grain growth, precipitation
and phase transformation.
 The INTEG Hot Strip
Mill Model has been validated for a variety of hot strip mills for
a variety of grades of steel and processing parameters. The design
and flexibility of the model allows the user to study both the thermal-mechanical
evolution of the strip and the microstructure/mechanical properties
evolution. Utilizing independent calculations for the various processes
being modeled allows the user to extend the range of the HSMM.
Utilizing the HSMM provides a useful tool to a variety of people
associated with the hot mill, including researchers, process technology
staff, quality assurance personnel and mill engineers. The model
can be easily set-up and once it is configured for a specific mill,
the user only needs to enter the processing parameters for the piece
of steel to be modeled. Piece dimensions, starting temperature distribution,
draft distribution and several other parameters are quickly entered.
The HSMM will then process the piece through the entire rolling process,
ultimately predicting the final mechanical properties of the steel,
while providing feedback on the temperatures, forces and microstructure
changes observed. Data is displayed to the user in both tabular and
graphical format with the capability to export the data to a spreadsheet.
The Hot Strip Mill Model can be used for a variety of applications.
Current users have utilized the HSMM to study mill configurations,
rolling schedules, and to gain detailed insight into various process
parameters not available with normal instrumentation (such as temperature
distribution, temperature rebound, transformation start points, etc.)
and online statistical based models.
The model is licensed and marketed under an exclusive agreement
with the American Iron and Steel Institute (AISI) and the US Department
of Energy (DOE). |
