Abstract

ABSTRACT This paper targets at the calculation of in-service deformation of a flange in a billet continuous casting machine due to thermal loading. In this regard, first, the thermal analyses of the mould will be thoroughly and accurately conducted. Henceforth, the heat flux profile from the melt to the mould is derived from the literature and, based on the limited temperature measurements, it is calibrated for the understudy mould. Moreover, for the upper part of the meniscus, the effect of radiation is considered as a heat flux profile with an exponential function. Subsequently, the thermo-mechanical analysis is conducted by applying the thermal load, as a temperature distribution, on the corresponding finite element (FE) model. The results of the analysis for the critical flange showed that the calculated deformation at the critical point, 1.08 mm, is close to the value reported by the manufacturer which is 1.25 mm.

基于有限温度测量的小方坯连铸机法兰热力学分析

本文针对方坯连铸机法兰在役热载荷变形进行了计算。在这方面，首先，将彻底准确地进行模具的热分析。从那时起，从熔体到模具的热通量分布从文献中推导出来，并基于有限的温度测量值，对其进行了校准。此外，对于弯液面的上部，辐射的影响被认为是具有指数函数的热通量分布。随后，通过在相应的有限元（FE）模型上施加作为温度分布的热载荷来进行热机械分析。临界翼缘的分析结果表明，临界点的计算变形为1.08 mm，接近制造商报告的1.25 毫米。
