An integrated mathematical model for forecasting final microstructure and mechanical properties has been
developed. The model provide an important tool to improve the quality of long products, and to develop the
new products.
A simulating software has been programmed. The calculated results by software are in good agreement
with measured data. The software can analyze temperature field and microstructures evolution of the rolled
steels in the high speed wire rods. The integrated mathematical model can also predict the interlamellar space
of pearlite and mechanical properties of rolled steels. It can be used to investigate the microstructures and
properties of high carbon wire rods and to provide the guidance to industry production.
The integrated mathematical model has been applied to get optimal range of the rolling parameters for the
desired mechanical properties. It is also useful for the development of new steel grades and the development of
optimized thermomechanical processing routes
