This paper presents a detection system for wheel billet end face angular deviation based on laser ranging method. Using three parallel lasers Irradiate the checking surface at the same time, the distance between the wheel billet end face and the laser sensors can be obtained, then the angle between the checking face and the reference plane is calculated by using the geometric theory and the sta...

In continuous casting, it is very important to predict and detect the internal cracks of billet in time for ensuring continuous production, improving product quality and reducing production costs. Clustering analysis (CA) method is adopted to do feature extraction and classification for on-site data, by which ladder parameter tables of processing parameters and defect grades of internal cracks ...

Metal forming process simulation requires a very high cost including the cost for dies, machine and material and tight process control since the process involve very huge pressure. A physical modeling technique is developed and initiates a new era of educational tool of simulating the process effectively. Several publications and findings have shown a potential of the techniques else where. The...

Ternary Mg–Y–Zn alloys have attracted considerable attention due to their excellent mechanical properties and unique microstructures. Microstructural variation and the resulting mechanical properties can be affected by various processing routes, particularly those involving severe plastic deformation of a cast billet. The following approach was used in this work to perform a comparative study: ...

The main objective of this paper is to study the effect of extrusion parameters (extrusion stresses and temperature) and die geometry, i.e. extrusion radius, on the extruded aluminum quality using FEM Simulation Technique. For this purpose, the general FEA Software ABAQUS was used to set up the finite element model of the warm aluminum extrusion in two dimensions (2D). Aluminum alloy Al-2014 wa...

Two decades of operating experience have shown that reducing the corner radius from 12–16 mm to 3 or 4 mm A finite element thermal stress model to compute is beneficial in reducing longitudinal corner cracking.4 In the thermomechanical state of the solidifying shell addition to lessening crack frequency, decreasing the corner during continuous casting of steel in a square billet radius also ten...

Johnny Carson as long time host of the Tonight show often appeared in the spoof role of Carnac the Magni cent, a mentalist who could magically read the contents of a sealed envelope. This is in fact a well known stock-in-trade trick of the mentalist's craft, known as billet reading . Here we propose a cryptographic solution to the problem of billet reading, apparently allowing a ciphertext to b...

There are a wide range of physical defects which occur during metal forming processes. These defects, which may occur on the surface or be internal, are undesirable not only because of the surface appearance, but because they may adversely affect the strength, formability and other manufacturing characteristics of the material. Some physical defects in metal forming processes such as rolling an...

Firstly, this text is introducing the traditional technology of vertical billet. Secondly, describing technological process and equipment principle about first second generation billet machine. Thirdly, illustrating machine’s superiorities by contrasting. Finally, we have put forward thought optimal to
