Thermal Imaging Systems Of Mould3D Simulation

The continuous Steel Casting which is one of the most important modern steelmaking technologies greatly promotes metallurgical industry, but the breakout brings huge losses to the production using this technology. Many domestic and foreign experts have devoted a great deal of energy and material to the study of breakout forecast system and made great achievements in breakout forecast through getting the temperature detected by thermocouple on the mould. However, this system only pays attention to breakout forecast but ignores the overall situation of the temperature field. Technicians and operators cannot grasp the temperature distribution of the whole copper mould. Thus they can not efficiently monitor the whole temperature field of the copper mould from all angles and can not provide more effective online auxiliary judgment method for breakout forecast system. The accuracy of breakout forecast becomes poor.Mould is the key component of continuous casting machinery. Its temperature distribution associates with breakout closely. It can improve the accuracy of breakout forecast to combine three-dimensional thermal imaging and traditional breakout forecast system.Experimental data in this paper are derived from historical data in Baoshan Iron and Steel (Co.Ltd.) Group Corporation’s breakout forecast system. Results of simulating thermal imaging indicate that the realization of three-dimensional temperature field provides breakout forecast with more evidence and visual guidance for practical operation.The content as follows:1.By analying working principle of continuous casting and binder breakout,it is known that mould temperature monitoring system for breakout forecast is important.by contrasting the method of numerical analysis we select the method of finite element analysis.2.The temperature field model was established and the boundary condition was given by consulting relevant books.3.Discrete equations for programming were deduced by using finite element method and the mathematical model.4.Color image was received by Ansys and some conclusions about effects of parameters were draw by analysis of the image. These conclusions play guiding roles in the continuous casting.It is useful for mould Parameter optimization.
