Special Features of Vacuum Ingot-Casting Process

Properties and Control of Fluxes for Ingot Casting and Continuous Casting

Present chemical-physical characteristics of ingot and continuous casting powders can be critically evaluated pointing out history of invention of these materials. In an original tone, pioneering nature of first developments of casting powders will be described, illustrating empirical know-how of casting powders technology, based on trial-and-error method. It will be originally emphasized that ...

A feasibility study of the partial squeeze and vacuum die casting process

A feasibility study of the partial squeeze and vacuum die casting process was performed to make defect-free casting products with excellent mechanical properties. The trial die casting process in this study was industrially implemented for producing a reaction shaft support made of a hyper eutectic Al±15%Si alloy. To combine the squeezing and vacuum effect, the plunger injection system was desi...

State of the Art in the Control of Inclusions during Steel Ingot Casting

This article extensively reviews published research on inclusions in ingot steel and defects on ingot products, methods to measure and detect inclusions in steel, the causes of exogenous inclusions, and the transport and entrapment of inclusions during fluid flow, segregation, and solidification of steel cast in ingot molds. Exogenous inclusions in ingots originate mainly from reoxidation of th...
