Recently, a new method of a press casting using greensand mold was proposed by our group as a means of ferrous casting. This method has advantages in terms of energy savings and cost because a sprue cup and runner channel are not needed. Still, it is important to pour accurately and quickly in this method. Therefore, a feedforward outflow control is presented by using a mathematical model and inverse dynamics. The outflow is measured by ...

67th World Foundry Congress

Shrinkage defect in an alloy steel casting for marine engine cylinder cover was estimated by numerical analysis with reference to casting variables such as riser and chiller. Retained melt modulus was employed as a prediction parameter in this study. Shrinkage defects were developed at the final solidification region. This is associated with hot spots, which could be controlled more effectively by adjusting the height of riser and by att...

Nonlinear modeling with Hydrodynamics and flow control using inverse pouring dynamics of tilting-ladle-type automatic pouring process Yoshiyuki Noda*, and Kazuhiko Terashima*,
* Department of Production Systems Engineering, Toyohashi University of Technology
67th World Foundry Congress

This paper is concerned with the pouring control of tilting-ladle-type automatic pouring systems in casting industries. A new approach to the modeling and control system of the pouring process is proposed. In the approach, the flow rate model is described by a nonlinear system with hydrodynamics. The flow rate control system is built by a feedfoward control using the inverse dynamics of the flow rate model. In this control system, contro...

67th World Foundry Congress

Metal matrix composites are engineered materials formed by the combination of two or more dissimilar materials (at least one of which is a metal) to obtain enhanced properties. In the present investigation Al-4.5%Cu alloy was used as the matrix and fly ash & silicon carbide (SiC) as filler material. The composite was produced using conventional foundry techniques. The particulates were added in 5%, 10% and 15% by weight to the molten...

67th World Foundry Congress

In the present investigation, Aluminium based particulate composites containing 15 weight percentages of two types of flyash particulates as reinforcement were synthesized using stir-casting method and their properties are compared. The properties like density, sliding wear, hardness, slurry erosive wear and corrosion resistance of the composites were investigated and their properties are compared. The results of wear studies have shown ...
