Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

Solidification rate of the casting affects greatly on the microstructure, quality as well as the mechanical properties of the casting. In centrifugal castings solidification rate is faster compared to gravity casting but still solidification depends on various process parameters like, die wall temperature, pouring temperature of the molten metal, wall thickness of the die and also rotational sp...

In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...

Heat transfer in the mold is the heart of the continuous casting process and its quantitative analysis was pioneered by Keith Brimacombe. With many different processes currently competing, it is appropriate to apply modeling to investigate the theoretical limits of continuous casting speed and productivity. The heat transfer rate during solidification processes drops with time so the shell thic...

Centrifugal casting is one of the advanced casting branches widely used in the metallurgical industry in which the centrifugal force helps strengthen the workpiece material. The present work attempt to study the effect of the horizontal and vertical centrifugal casting parameters included the centrifugal mold rotation speeds and G-factors values on the quality of the product. The work has been ...

A mathematical model of heat transfer in continuous casting copper slabs capable of producing experimental data has been constructed and validated against experimental data provided by the management of Copper Refineries Ltd., Townsville plant in Australia. It has been used to predict the effects of major casting variables; metal temperature, casting speed and metal conductivity. The results ca...

IntroductIon Solidification structure and macrosegregation have great influence on the quality of high carbon steels. Center segregation in high carbon steel results in a high concentrations of chemical components especially carbon element and has a great influence on the quality of wire rod [1-3]. Wire rod with center cementite network resulting from severe segregation not only shows low ducti...

Primljeno (Received): 2011-11-07 Prihvaćeno (Accepted): 2012-03-15 Original scientific paper Abstract: Pressure die casting is the method used for forcing molten metal into mould cavities under high pressure and at high speed (10 100 m.s). Pressure die casting is a highly productive method of casting parts with low dimensions tolerance and high surface quality. From the point of view of product...

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...
