| Abstract: | A mathematic model to predict the microstructure of Nb-Ti micro-alloyed slab in the heating process of hot rolling was developed based on thermo-mechanical simulation tests.This paper describes the microstructure transition of micro-alloyed slab during heating,gives the austenite grain coarsening temperature and analyzes the suitable heating temperatures for control rolling and control cooling. |
