Numerical simulation of billet heating

Chen Guanjun

Strategic Study of CAE 2010, Volume 12, Issue 2, Pages 57-61

Abstract:

According to the case of billet heating in a regenerative type heatingfurnace, the temperature distributing of billet about upper surface, undersurface and center surfacelength and width is studied by computational fluid dynamics (CFD)in this article, and the questions of billetThe relation of different thick billet and the heating time is simulated and studied, the result of simulationThe above result of study can offer foundation for the establishment and optimizing of billet heating

Original Position Statistic Distribution Analysis (OPA) Study on the Quality of Billet

Wang Haizhou,Li Meiling,Chen Jiwen,Wu Chao

Strategic Study of CAE 2003, Volume 5, Issue 10, Pages 34-42

Abstract: The weight ratio of carbon content at each original position of billet was suggested to express the degreeratio of median value (K) at 95 % of confidence limit of weight ratio, were provided for practical billetThe quality differences among the billet samples were explained reasonably by above method.Thus, this technique can be used to judge the quality of billet samples.

Robust optimization of the billet for isothermal local loading transitional region of a Ti-alloy rib-web

Ke WEI, Xiaoguang FAN, Mei ZHAN, Miao MENG

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 3, Pages 376-384 doi: 10.1007/s11465-018-0500-3

Abstract:

Billet optimization can greatly improve the forming quality of the transitional region in the isothermalmay be deteriorated by uncontrollable factors, such as the manufacturing tolerance of the preforming billetThus, a dual-response surface method (RSM)-based robust optimization of the billet was proposed to addressmean and standard deviation of the die underfilling rate by considering the size parameters of the billetSubsequently, an optimum solution was derived to achieve the robust optimization of the billet.

Original position statistic distribution analysis (OPA) on the quality of mould steel billet

Wang Haizhou,Li Meiling,Zhang Xiuxin,Wu Chao

Strategic Study of CAE 2009, Volume 11, Issue 10, Pages 39-47

Abstract:

Through the analysis of mould steel from different sources by the original position statistic distribution analysis (OPA), new information on the position, state and content distribution of each chemical component in the cross section of mould steel was obtained in a relatively wide range. As a result, the differences among the parameters of mould steel from different sources were uantitatively characterized, including the biggest segregation, the statistic degree of segregation, statistic degree of accord with contents (statistic degree of homogeneity), the statistic density as well as the content, variety and statistic size distribution of the inclusions. The experimental results could be used as reference for analyzing the quality variance of mould steel from different sources.
