The present article deals with a composite casting process that allows to produce bilayer AlSn6-Al strips based on the technique of horizontal continuous casting. In the first part experimental investigations on the production of a single layer AlSn6 strip are described. Afterwards essential results of basic compound casting trials using simple test specimen are presented to define the thermal ...

A full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (SEN) was constructed. On the basis of the dimensionless Reynolds and Froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. In order to determine the optimum ope...

Foundries represent an important sector of the manufacturing industry and these foundry industries in developing countries suffer from poor quality and productivity due to number of process parameters involved in the casting process. Even in a completely controlled process, defects in casting are observed and hence casting process is also known as process of uncertainty which challenges explana...

Casting solidification brings to the shrinkage in the liquid state, solidification shrinkage and shrinkage in the solid state. Recently, technologies of die and gravity casting have increased the number of highly functional castings, which have been characterized with the very complex geometry. due to the different wall thickness in these castings, as well as the high solidification rates, prem...

Abstract This paper presents an improved ray casting algorithm, in order to solve the problems of powerful computing capacity and slow rendering velocity. In the course of ray casting volume rendering, an algorithm of ICT slice images original data field 2D maximum entropy threshold segmentation prior preprocessing is proposed. It is used to define the extent of threshold, and research the opti...

A concept for the casting of metallic fuels pins containing low vapor pressure materials is presented and discussed. The important physics of this concept include the mass transport of americium from the melt, the induction heating and stirring of the melt, plus the casting of long slender fuel rods. This paper discusses and presents preliminary modeling results for the casting of long, slender...

The effect of squeeze casting process parameters on wear behavior of AC2A aluminium alloy was primarily investigated in this experimental study. Five process parameters, namely squeeze pressure, pouring temperature, die temperature, die material and compression time, each at four levels were chosen and sixteen experimental runs based on L16 orthogonal array were performed. From analysis of vari...
