6. Quality management system for new variety of development（1）

1. Quality management system and modification |
At present, various companies mainly use experience method to design manually in
the development of new steel grades and new products. A new product development
management software package that completely describes the design process,
combined with the existing mature models, can greatly optimize the design
process. Similar steel grades and similar production processes are the main
reference for new product design. Here, designers can be allowed to input their
own correction model to consider the performance difference caused by the
difference between steel grades and production processes, or the correction
model can be recommended by the management system to collect the research
results of researchers around the world on various steel grades and products.

2. Hot strength (flow stress) and cold strength (mechanical property of rolled
steel) |
In the process of steel forming, the thermal strength (Flow Stress) is directly
related to the final cold strength (product mechanical properties) through
chemical composition, phase structure and grain size. My Level 2 Model is famous
for its high precision, and the rolling force error is only 1 / 2 to 1 / 3 of
that of the western advanced Level 2 System, that is, the hard-and-thin products
of hot continuous rolling are less than 1%, and the hard-and-thin products of
reversible rolling of medium and heavy plates are less than 5%. At the same
time, the main problem in performance prediction is the limited accuracy.
Through the ingenious combination of the post rolling product performance
prediction model and the Level 2 Model, the quality of performance prediction
can be greatly improved by relying on the high precision brought by the
intelligent learning and continuous optimization of the Level 2 Model.
At present, the main reason for the low accuracy of product performance
prediction is that it is impossible to accurately calculate the grain size after
rolling. When the accuracy of the Level 2 Model is sufficient, the rolling force
model with high-quality metallurgic model can be used to calculate the grain
size and residual stress of each rolling pass, especially before cooling. |
