Quality Prediction of Cast Ingots

This paper shows how the quality of a cast ingot can be predicted using simulation. Emphasis is laid on those casting defects that will affect the quality of the forged end-product. The simulation of ingot casting starts with tapping a steel melt of a given chemistry from a ladle. The teeming, solidification and cooling of the ingot are...

Improved ingot casting by using numerical simulation

This paper concentrates on the influence of the heat flow through the mould walls on casting quality. The determination of heat transfer coefficients by reverse engineering is described. Normally, due to missing knowledge, a heat transfer coefficient between the solidifying shell and the mould surface which is invariant from the ingot bottom to...

Material combinations in lightweight casting components

Aluminum und magnesium castings play a major role in light-weight casting. These fields of application are being extended continually, and the specific demands on materials are increasing. More often the mechanical and tribological properties of the casting materials are insufficient, the operating temperatures are too high, or the environment...

Real-World Application of Core Simulation for Process Optimization

The making of cores still creates surprises for tool and corebox makers. Core related defects are a significant cost factor of casting production. The layout of coreboxes traditionally follows an experienced-based trial and error process until a satisfactory core quality is achieved. The ramp-up of new tools for production usually requires...

Simulation of the entire core production process

The simulation of the core making process can significantly improve the predictability of the entire casting production process. The technical and economic feasibility of sand cores can be predetermined prior to production as designers evaluate the feasibility of their designs and consider...
