根据微波烧结的特点、传热学原理和有限元求解方法,建立了浸入式水口导流装置三维温度场的数学模型。给出了导流装置的边界条件和初始条件,使用ANSYS软件,得出了浸入式水口导流装置的X方向温度梯度分布云图,以及导流装置上任意选定点的温度-时间曲线分布。结果表明,微波烧结法时间短,而且所形成的温度梯度小,能够节省能源,为浸入式水口的发展提供有效的参考,也为高效连铸生产提供依据。
According to the characteristics of microwave sintering, heat transfer theory and finite element method, a mathematical model of three-dimensional temperature field of submerged nozzle guide was established. The boundary conditions and initial conditions of the deflector are given. Using the software ANSYS, the X-directional temperature gradient distribution of the submerged nozzle deflector is obtained, and the temperature-time curve distribution of any selected point on the deflector is obtained. The results show that the microwave sintering method has short time and small temperature gradient, which can save energy, provide an effective reference for the development of submerged nozzle, and provide the basis for high efficiency continuous casting.
