Microstructure Simulation Of Thin Slab Continuous Casting And Continuous Rolling(CSP)Process

The technology of continuous casting and rolling is one of the most revolutionary in iron and steel industry nowadays, thin slab continuous casting and rolling process has been developed rapidly now, It has lead to the innovation of producing technique and equipment components. It has also provided opportunities of productive structure adjustment and enterprise technical renovation for our iron and steel industry, the representative of which is the type of CSP,This paper firstly has discussed the essence of the near net shape continuous casting rolling technology, Its press feature and pivotal techniques and reviews the six principal processes and introduces its specialty of metallurgy. Then, Temperature field of thin slab continuous casting and continuous rolling section is analyzed by endogenous hot transient state finite elements method, Have set up the finite element equation of rolling a two-dimentional section and Rational temperature border condition, Solve the temperature field of Lean towards differential equation by MATLAB toolbox., Get the temperature profile in the section of different moments, After referring to a large number of national and international articles , Physical metallurgy models were selected , and models which used to simulate the rolling of microstructural evolution were established during rolling and programmed ,The results of the calculation showed that using MATLAB Lean towards differential equation toolbox calculated section temperature field and temperature changing of roll ones, and modelling program simulated microstructural,evolution during rolling and can get satisfied results.
