The main components of molding sand used in casting are sand, clay and water. composition the has a great influence on properties casting. In order to obtain high-quality castings, it is important manage that affect such as especially green compression strength compactability. this work, compactability predicted through machine learning technique using processing data obtained from foundry inpu...

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 failures of alloys in dental technology should be the exception, not the rule. They have to be detected in time and associated with possible causes. For the experimental part base metal alloys single tooth restorations were achieved using the conventional lost wax process for casting in order to be evaluated. Some casting defects obtained during the experimental part are exemplified: in...

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...

During continuous casting, argon blowing from tundish cover (ABTC) can greatly prevent the flow of remaining air and decrease reoxidation molten steel in tundish. In current study, a numerical model based on two-strand slab casting machine was established to investigate feasibility evaluate protective effect ABTC process. The influence operation parameters, including sealing schemes holes rate ...

OBJECTIVE Assessment of surgical outcomes of biceps tendon lengthening (BTL) surgery in obstetric brachial plexus injury (OBPI) patients with elbow flexion contractures, who had unsuccessful serial casting. BACKGROUND Serial casting and splinting have been shown to be effective in correcting elbow flexion contractures in OBPI. However, the possibilities of radial head dislocations and other c...

The objectives in this work were to develop, calibrate, and apply a model to predict ideal taper profiles down the narrow faces of the SIDERAR slab casting mold for several different casting speeds, steel grades, flux powder compositions, and widths. A significant amount of original research was undertaken for this challenging problem. A finite difference model of transient 1-D heat conduction ...

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...

The 3D sand printing (3DSP), by binder jetting technology for rapid casting, has a pivotal role in promoting the development of traditional casting industry as result producing high-quality and economical molds. This work presents an approach monitoring analyzing powder sand-bed images to serve realtime control system 3DSP machine. A deep residual network (ResNet) is used classify defects occur...

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...
