摘要
针对两种铸钢材料ZG0Cr13Ni4Mo和ZG230-450,详细地研究了其保温冒口计算模型及计算软件,以指导保温冒口工艺的设计。文中采用了数学分析、数值计算、浇注实验和无损检测等多种研究方法,比较和分析了三次方程法、周界商法及Q参数法三种解析法的特点及适用性。结果表明三次方程法更适合做保温冒口的计算模型,并以此开发了相应的计算软件。研究方法和结果对其他种类铸钢件保温冒口设计和计算有借鉴和指导作用。
The calculating model and calculating software for insulating risers were researched in detail on two kinds of cast steels ZGOCr13Ni4Mo and ZG230-450 in order to guide the technological design of insulating risers. By means of various research methods such as mathematical analysis, numerical calculation, casting experiment and nondestructive testing, the characteristics and applicability of mathematical analytic methods using Cubic Equation, Perimetrischen Quotient or Q-number were compared and analyzed. It was found that the Cubic Equation method is suitably used as the calculating model for insulating risers. In addition, the corresponding calculating software is developed. The research methods and results can be reference for the technological design and calculation of insulating risers used for other kinds of cast steels.
