Application of physical simulation and mathematical modelling to predict the occurrence of defects during continuous casting of steel

摘要

In the paper the usability of the mathematical modelling and physical simulation for design and correction of continuous casting of steel characterized by substantial susceptibility to heat cracking has been presented. It was shown that the best solution is the application of both these methods where the simulation is used for generation of material characteristics which allow to draw conclusions about occurring of cracks on edges and surface of concast ingots. The fundamental data obtained during the physical simulation comprise the dependence of narrowing and tensile strength from the temperature. The usability of these methods to describe the phenomena occurring in concast ingot has been shown on the example of continuous casting of 18G2A steel.
