Modeling the Formation of Transverse Weld during Billet-on-Billet Extrusion
A comprehensive mathematical model of the hot extrusion process for aluminum alloys has been developed and validated. The plasticity module was developed using a commercial finite element package, DEFORM-2D, a transient Lagrangian model which couples the thermal and deformation phenomena. Validation of the model against industrial data indicated that it gave excellent predictions of the pressur...
متن کاملUne grammaire formelle du créole martiniquais pour la génération automatique
Nous présenterons dans cette communication les premiers travaux de modélisation informatique d’une grammaire de la langue créole martiniquaise, en nous inspirant des descriptions fonctionnelles de Damoiseau (1984) ainsi que du manuel de Pinalie & Bernabé (1999). Prenant appui sur des travaux antérieurs en génération de texte (Vaillant, 1997), nous utilisons un formalisme de grammaires d’unifica...
متن کاملAn Estimation of a Billet Temperature during Reheating Furnace Operation
Reheating furnace is an essential facility of a rod mill plant where a billet is heated to the required rolling temperature so that it can be milled to produce wire. Although it is very important to obtain information on billet temperatures, it is not feasible during furnace operation. Consequently, a billet temperature profile should be estimated. Moreover, this estimation should be done withi...
متن کاملPrediction of coefficient of friction for Aluminum Billet
In the metal forming process, a realistic frictional coefficient must be specified at the die/work piece interface. Several methods are developed to evaluate friction coefficient in large deformation processes. This paper presents the concept of friction calibration map to determine different frictional conditions between interfaces of die and billet in the upsetting process. One such map is ge...
متن کاملDefects Detection of Billet Surface Using Optimized Gabor Filters
This paper deals with a defects detection algorithm for billet surface. To get good performance, detection algorithm has to solve several difficult problems such as shape of a billet, many kinds of defects, much scale. Especially, the scale, that is a metallic oxide on steel surface, makes worse severely the performance of detection. To solve above problems, this paper presents a new effective ...
