Study and Application of Computer Simulation of Secondary Cooling in Slab Continuous Casting Process

The Computer simulation of secondary cooling in slab continuous casting is a very important way,which can accurately forecast and analyze the effect of technological parameter on the casting.Based on the concept of finite thin section along the direction of casting speed,the mathematical model of heat transfer in slab continuous casting process has been established,and the computer simulation software of secondary cooling in slab continuous casting was developed by Visual Basic 6.0,which could be used to simulate the temperature field and solidification of continuous casting process,and optimize the technology of secondary cooling zones.The slab surface temperature was measured by the infrared temperature measurement gauge,and measurement results were basically in accordance with the simulation result,it shows that the computer simulation software of secondary cooling in slab continuous casting is reliable.
