3. Plate shape and other shape quality parameters |
The residual stress is the key parameter of plate shape control. Other models
considered for predicting the mechanical properties of steel, are such as phase
decomposition model, precipitation model and mechanical property calculation
during accelerated cooling. Other quality parameters, such as plate shape,
center wave, edge wave, camber, etc., can also be predicted by the quality
management system. Due to the limited resources in the rolling process, it is to
make effective use of resources for machine learning.
At the same time, I have collected the rolling process parameters of large
number pieces of steel from companies in a large number of projects in the past,
and each piece of steel has several dozen of data, including plate shape data.
These data have significance in guiding the production process and optimizing
the plate shape. For example, I personally witnessed the strange shape in some
companies' hard-and-thin products after water curtain cooling. Therefore,
combined with all kinds of data, a set of models for optimizing the production
process and specifically for the plate type of hard-and-thin products were
produced. At the same time, it can also be effectively optimized for making full
use of the roll bending device and reducing camber by realizing uniform
reduction on the left- and right-hand sides.

4. Field case data and application |
I have collected and optimized the data from millions of pieces of steel in
previous projects. Based on the microstructure model and intelligent learning of
the New-Generation Level 2 System, combined with the existing uniform
deformation technology and referring to a large number of existing data, a
complete set of optimization from rolling process stability, performance
prediction to plate shape control can be achieved.
All models are suitable for reversible rolling, hot continuous rolling and other
types of flat rolling. Although my business field in intelligent manufacturing
has been extended to all new materials, new energy and high-end equipment in
manufacturing industry. My model development in metal material rolling for more
than 30 years is still the core field. |
