Analysis of Temperature Field and Verification Tests on Electro slag Induct Continuous Unidirectional Solidification Process
【摘要】 自行研制了电渣感应连续定向凝固系统,该系统保证金属液能连续供给,结晶器能连续加热及结晶器轴向存在一定的温度梯度。本系统可用红外线测温仪控制结晶器出口的温度,用热电偶控制结晶器内的温度,用位移传感器控制拉伸速度,实现了对系统主要工艺参数进行监控。本文对此系统的传热过程进行了数值模拟并进行了实验验证,结果表明:所得试样的轴向温度分布与固液界面位置的理论计算值与实验值基本吻合。这样可以利用计算结果来预定工艺参数的范围,为指导电渣感应连续定向凝固的生产奠定了基础
【Abstract】 The equipment of continuous directional solidification using electroslag melting and induced heating of freezer is researched .There are three functions of this equipment,i.e.melting metal can be continuous supplied,freezer can continuous heat and there is an axial temperature gradient in freezer.The outlet temperature of freezer is controlled by infrared thermosistor,the inside temperature of freezer is controlled by thermocouple and the drawing velocity is controlled through displacement sensor.In this paper ,heat transfer of sample is simulated by computer and experiment is carried out in this equipment.The results show that the theoretical value of axial temperature and place of solid liquid interface are consistent with the experiment value.
