IN order to remain competitive in the worldwide market for continuously cast steel, steel producers are finding it increasingly important to implement process control improvements. Through superior production process monitoring and control, producers are improving steel quality and are meeting customers’ requirements for steel size, grade, quantity, and properties at the lowest cost. Computer m...

Aluminium disc wheels intended for normal use in passenger cars are commonly produced by gravity casting. If the cooling process and the initial temperature of the mould are not well controlled, shrinkage cavity will occur after solidification, causing leakage in the disc wheel. In this research, a casting simulation software is used to simulate the casting process of aluminium wheels. The cast...

This study deals with the experimental measurements and numerical predictions of alloy shrinkage factors (SFs) related to the investment casting process. The dimensions of the A356 aluminum alloy casting were determined from the numerical simulation results of solidification, heat transfer, fluid dynamics, and deformation phenomena. The investment casting process was carried out using wax patte...

AS COMPUTATIONAL MODELS MATURE, their practical benefit to improving casting processes is growing. Accurate calculation of fluid velocities, temperature, microstructure, and stress evolution is just the first step. Achieving tangible improvements to casting processes requires the accurate prediction of actual casting defects and product properties. Defects that form during solidification are im...

Purpose: The aim of the work is presents the influence of casting method and anodic treatment parameters on properties, thickness and structure of an anodic layer formed on aluminium casting alloys. Design/methodology/approach: Investigations were carried out on the laser profile measurement gauge MicroProf from company FRT, abrasive wear test was made with using ABR-8251 equipment delivered by...

Serial casting aims to improve an equinus gait pattern in children with spastic cerebral palsy (SCP). We evaluated the effect of short-term stretch casting on gait in children with SCP, compared to the natural history. A crossover trial, consisting of a control phase and a casting phase, was conducted with children randomised into two groups. Both groups were assessed clinically, and using 3D g...

Thin slab casting and rolling was originally developed as a low cost alternative to a conventional casting and rolling process route. However, due to the technological restrictions of the first generation plants, only limited quality and productivity goals could be achieved, questioning its further application to more advanced applications. This paper describes the original contributions that D...

The twin-roll strip casting process is a typical steel-strip production method which combines continuous casting and hot rolling process. The production line from molten liquid steel to the final steel-strip is shortened and the production cost is reduced significantly compared to the conventional continuous casting. The twin-roll strip casting process can produce 1-5 mm thin steel strip direct...

There are about 33 processes commercially available for the production of aluminium castings. About 70% of the castings are produced using conventional high-pressure die-casting process. It’s main drawbacks are 1) Air and gas blow holes 2) Unable to weld 3) unable to heat treat to enhance mechanical properties. To overcome these, many modern processes have been invented. A few of them are 1) Hi...
