| Abstract: | The thesis studies the basis of the investigations on the theory of controlled cooling in residual heat treatment of high strength reinforcement and the phase transformation of low carbon steel,the mathematical model of cooling is set up.The investigations show that the model is feasible,and the cooling intensity can be modulated to produce steady and coincident bars by logical analysis and deducing the technical parameters as the composition,end-rolling velocity and temperature,self-tempering temperature.The cooling program is adaptive as the varieties of process. |
