RH真空处理过程优化及控制
|
摘要
随着RH真空处理设备和工艺技术的不断进步，RH真空处理已在众多炉外精炼中起着不可替代的重要作用。RH真空处理的主要任务是：
●脱气
●脱氧
●脱碳
●脱硫、脱磷
●精确成分调整
●均匀钢水成分
●提高钢水纯净度
●温度均匀与调整
在RH处理过程中，采用过程计算机与过程控制数学模型对RH生产过程进行优化控制，对进一步稳定提高钢质量，实现高效、低耗生产具有重要意义。
本文分析了RH真空处理的基本原理，对RH真空处理的脱气模型、脱氧模型、脱碳模型、合金计算模型、温度计算模型作了详细的介绍，同时对这些模型在RH过程计算机系统的实现作了详细论述。
With the continuous development of RH vacuum degassing technology, it has been becoming more and more important. The main task of RH is:
degassing
deoxidation
decarburization
desulfurization, dephosphor
exactly chemical tuning
steel homogenisation
increase steel purity
temperature tuning
It improve the quality of liquid steel, increase yield and reduce energy consumption to adopt process computer and mathematical model in RH vacuum refining process.
This dissertation states the principles of RH degassing, the degassing model, the deoxidation model, the decarburisation model, the alloying model, and the temperature calculation model. Expatiates in detail on the realization of these models.
