Electrical capacitance tomography (ECT) is used to image the permittivity distribution of an object by measuring the mutual electrical capacitance between sets of electrodes mounted on its periphery. Reconstruction of the cross-section images in ECT system from the capacitance measurements is a nonlinear and illposed inverse problem. However, there are many algorithms to solve the inverse probl...
Casting had symbolic significance and was strictly controlled in the Shang dynasty of ancient China. Vessel casting was mainly distributed around the Shang capital, Yin Ruins, which indicates a rigorous centralization of authority. Thus, for a casting mold to be excavated far from the capital region is rare. In addition to some bronze vessel molds excavated at the Buyao Village site, another ke...
A three-dimensional mathematical and physical model coupling with the heat transfer and the flow of molten metal in the centrifugal casting of the high speed steel roll was established by using CFD software FLUENT. It can be used to analyze the distribution of the temperature filed and the flow filed in the centrifugal casting under the gravity, the electromagnetic stirring force and the centri...
An Optimization Study on Maximizing the Earning Power of Casting Industry for Management through TPI
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...
We present a novel algorithm for visibility approximation that is substantially faster than ray casting based algorithms. The algorithm does not require extensive preprocessing or specialized hardware as most other algorithms do. We test this algorithm in several settings: rural, mountainous and urban areas, with different view ranges and grid cell sizes. By changing the size of the grid cells ...
Foundries for the metal-casting industry plays a vital role to generate byproducts such as used foundry sand. Metal foundries use large amounts of the metal casting process. Foundries successfully recycle and reuse the sand many times in a foundry but by using repeated usage of Used foundry-sand vary due to the type of equipment used for foundry processing, the types of additives, the number of...
