The continuous roll casting process (CRC), consisting of continuous strip casting between rolls, is now well known. It was introduced by the SCAL Company (Pechiney Ugine Kuhlmann Group) 60 years ago 1 . The process consists of solidifying aluminum or aluminum alloys between the water-cooled rolls of a duo rolling mill. From the moment when solidification is completed to the moment when the stri...

The present work analyses different parameters of pressure die casting to minimize the casting defects. Pressure diecasting is usually applied for casting of aluminium alloys. Good surface finish with required tolerances and dimensional accuracy can be achieved by optimization of controllable process parameters such as solidification time, molten temperature, filling time, injection pressure an...

aluminum anodes have been widely used in the cathodic protection of marine structures. however there are conditions in which these anodes become passivated or face some localized or unwanted corrosion, which influences their efficiency. addition of alloying elements such as zn and in not only have improved the efficiency of the anodes but also the effect of casting parameters such as ultra melt...

Components for engineering systems, such as gas turbines and jet engines operating at high temperature are usually produced in superalloys. The investment casting process is most widely used for manufacturing these components due to the ability of the process to produce parts with complex geometries to close dimensional tolerances. Other processing routes are less advantageous due to high mecha...

The aim of this work is to improve the quality of castings by minimizing defects and scrap through the analysis of the data generated by High Pressure Die Casting (HPDC) Machines using computational intelligence techniques. Casting is a complex process· that is affected by the interdependence of die casting process parameters on each other such that changes in one parameter results in changes i...

The use of aluminum alloys are of significant use in industry. Studying of design parameters of such products is important as not much work has been done for optimizing it. The generic formulation involves the flow, velocity, continuity fluid dynamics and shape related issues. The time for filling the mould and shape factor also play major role in performance of the casting process. In this pap...

In today’s world a casting production without any defect is almost impossible. After the application of various optimization techniques and process we still are not able to get the defect free castings. So it is critically important to analyze the root cause of casting defect with in the process itself, so that any changes which can hamper the defect intensity can be invoked at the time of manu...

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...

important activities of die-casting die design. In normal practice, determine therunner and gating designparameters. These parameters are simulations on a computer and dry runs on adie-casting machine These iterative activities increase the manufacturing lead time and makes A system which could reduce the iterations and make the presentsa computer-aided system for runner and gating system gener...
