The control system of PWM converter in hydraulic drive structure of the mold oscillation mechanism is used for prevent distortions of the mold movement. It is based on collecting data from accelerometers. This system can be useful for many metallurgical plants of Ukraine and overseas where continuous casting technology is used.

Freckle defects usually appear on the surface of castings and industrial ingots during the directional solidification process and most of them are located near the interface between the shell mold and superalloys. Ceramic cores create more interfaces in the directionally solidified (DS) and single crystal (SX) hollow turbine blades. In order to investigate the location of freckle occurrence in ...

The Vickers hardness of the cross-sectioned area of titanium castings made from an experimental resin-bonded calcia investment and three commercial investments was evaluated. The microstructure and element distribution of the surface zone were analyzed using an EPMA. The results showed that the high hardness of the casting surface could be decreased using the experimental investment. The hardne...

As computer power increases, computational models are able to contribute more to the understanding and design of complex processes such as the continuous casting of steel. Fluid flow models can now include phenomena such as transient behavior during steady casting, including particle transport, capture and removal. Heat flow models can include interfacial slag layer heat, mass and momentum bala...

The quality of continuous-cast steel is greatly influenced by fluid flow in the mold, particularly at the meniscus. Recent examples of computational model applications at the University of Illinois are presented to investigate the formation of several different types of defects related to flow phenomena. The amount of gas injection into the tundish nozzle to avoid air aspiration is quantified b...

Casting has various processes like Pre casting Processes, pattern making, core making, molding and mold assembly making, Casting Processes, furnace charging, melting, holding and pouring, and Post casting Processes, shakeout, inspection and dispatch etc. In India there are many foundry have followed conventional and manual operations. Today’s competitive environment has, lower manufacturing cos...

In the present work it has been shown that FEA software like ANSYS may play an important role in predicting cast defect before the actual casting. Transient thermal analysis and Couple-Field analysis in ANSYS can predict temperature distribution and thermal stress distribution in the casting after solidification very accurately. This fact has been proved by validating a transient thermal analys...

The attachment probability of inclusions on a bubble surface is investigated based on fundamental fluid flow simulations, incorporating the inclusion trajectory and sliding time of each individual inclusion along the bubble surface as a function of particle and bubble size. Then, the turbulent fluid flow in a typical continuous casting mold, trajectories of bubbles and their path length in the ...
