EVALUATION OF PRESSURE EFFECT ON HEAT TRANSFER COEFFICIENT AT THE METAL- MOLD INTERFACE FOR CASTING OF A356 AL ALLOY
Abstract: During solidification and casting in metallic molds, the heat flow is controlled by the thermal resistance at the casting-mold interface. Thus heat transfer coefficient at the metal- mold interface has a predominant effect on the rate of heat transfer. In some processes such as low pressure and die-casting, the effect of pressure on molten metal will affect the rate of heat transfer a...
متن کاملGating Design Optimization for Improvement in Yield of Casting
Casting has many process variations depending upon the material, the type of pattern, mould and the pouring technique like sand casting, investment casting, die casting, squeeze casting and lost foam casting. Sand casting is the most widely used process which can be used to produce intricate parts in almost every metal that can be melted. Casting defects analysis is process of finding the root ...
متن کاملAn Investigation into the Effective Heat Transfer Coefficient in the Casting of Aluminum in a Green-Sand Mold
This study commences by performing an experimental investigation to measure the temperature distribution within a casting system comprising a cylindrical aluminum casting and a green-sand mold. The experimental temperature measurements are then used to compute the effective heat transfer coefficient at the mold/metal interface using four different formulae. In the temperature measurement, a sym...
متن کاملReal-time Embedded Sensing for Process Monitoring and Quality Control in the Lost Foam Casting Process
The Lost Foam Casting (LFC) process employs a sacrificial foam replica of the desired casting that is supported by an unbonded sand mold through an overhead raining and flask vibration stage. Generally, the raining and vibration is programmed to a pattern-specific schedule to adequately promote fluidized sand flow into pattern cavities and produce proper densification. Currently, a lengthy tria...
متن کاملNumerical Investigation on the Effect of Mold Design on Shrinkage of Sand Casted Multistage BB3-6×6 Pump Casing (RESEARCH NOTE)
Design and manufacturing technology of high pressure multistage pumps which are commonly utilized in oil and gas industries, used to be imported from foreign companies. Due to international sanctions against I. R. Iran, it started to be designed and launched domestically. Nowadays all production lines including design, manufacturing and testing of these pumps have been performed by Iranian expe...
