通过分析熔体特性与槽膛内形的关系以及参数随时间变化的规律，将影响槽膛内形的诸多工艺参数分为静态影响因素和动态影响因素两类；详细分析了动态影响因素的影响作用，并给出了多个动态影响因素对槽膛内形的数值估算方法。在此基础上，提出了能初步应用于现场的槽膛内形在线动态仿真技术方案 By analyzing the relationship between the characteristics of the melt and the internal shape of the chamber and the law of the parameters changing with time, the process parameters that affect the internal shape of the chamber are divided into static and dynamic factors. The influence of the dynamic influencing factors And gives a method to estimate the numerical value of the internal shape of the groove by multiple dynamic influencing factors. On this basis, the on-line dynamic simulation technology of slot shape in the chamber can be preliminarily put forward
