Steel Applications
This section provides a number of
steel mill applications for design and
development engineers. We will gradually expand the range of applications from
rolling to other metal forming processes, and eventually to the whole
metallurgical/material engineering.
Those applications hide the complexity of the engineering processes, so
to
allow virtually any plant engineer to perform
even the very complicated
calculations such as the
prediction of microstructure
and rolled steel properties and
the calculation for
cross-sectional temperature
distribution pass by pass
with finite differential method.
Roll Design - AutoForm
There are several pieces of software that allow rolling mill engineers to
perform roll pass design by simply filling in input parameters. No advanced
knowledge on roll pass is required to perform a design job. This set of
applications includes:
-
Round-Oval-Round -
2 pass combination, Round-Oval and Oval-Round passes.
-
Square-Diamond-Square
- 2 pass combination, Diamond-Square and Square-Diamond passes.
-
Billet-Box-Square-Oval-Round -
4-pass roughing train, to roll from square billet to round.
-
Billet-Box-Oval-Round - 3-pass
roughing train, to roll from square billet to round.
Roll Design - FreeForm
This set of programs gives roll pass designers full freedom in designing
groove and pass parameters and specify spread behavior of metal. High-quality
spread and forward slip models are provided as default. These powerful
packages also incorporate tension correction for spread and forward slip into
the metal deformation prediction. They can be used not only to design new
passes, but also to study and improve the existing ones. The applications
include:
-
Round-Oval-Round -
Round-Oval-Round sequence with unlimited number of passes.
-
Square-Diamond-Square
- Square-Diamond-Square sequence with unlimited number of passes.
Mill load
A list of programs are used to calculate roll separating force, torque and
power requirements during hot rolling of wire rod. They cover following passes
or pass sequences:
-
Round-Oval (1
pass)
-
Oval-Round (1 pass)
-
Round-Oval-Round (2 passes)
-
Square-Oval (1
pass)
-
Box-Box
(1 pass)
-
Square-Diamond
(1 pass)
-
Diamond-Square
(1 pass)
-
Square-Diamond-Square
(2 passes)
-
General Estimation (1 passes)
Temperature during rolling and controlled
cooling
This is a program developed with finite differential method. It is used to
predict the cross-sectional temperature profile during rolling and controlled
cooling (water-box cooling). Temperature profile in multiple
stages (rolling, air cooling and controlled cooling) can be determined.
Microstructure
This application, equipped with various microstructural models, allows average
engineering personnel to simulate very complicated microstructural processes,
by simply filling in several process parameters.
