low coiling temperatures
Abstract
In order to meet the needs of their customers, steel makers are striving to make a variety of
new grades of steel with higher strengths and more complex microstructures. Advanced High
Strength Steels (AHSS) are required to meet new applications. Steel companies need to be
able to develop these new steels in a cost-effective way and get them to market as fast as they
can while manufacturing them within the constraints of their mill configuration. Lake Erie
Steel (A Stelco Company) was able to successfully develop an AHSS with the aid of the INTEG
Hot Strip Mill Model (HSMM). The HSMM effectively modeled the low coiling temperatures
required for Hot Rolled Dual Phase steel. The HSMM enabled Lake Erie Steel to develop an
initial rolling mill schedule, including the spray bank set-up for the run out table, and reduce
the number of trials needed and correspondingly the cost of mill time.
