Molten metal cleanliness when casting aluminium slabs

Molten metal cleanliness when casting aluminium slabs – the basics! Molten metal cleanliness is one of the key challenges for most casthouses. They must produce a slab with a sufficiently low level of hydrogen, alkali metals (mainly sodium) and inclusions to make the finished product suitable for its

Molten Light Metal Processing: Part One :: Total Materia

Generally, the historic practices of fluxing, metal refining, deoxidation, degassing, and grain refining have been used, and they apply to virtually all nonferrous metal systems. In addition, molten metal pumping and filtration are two somewhat newer but now commonly practiced technologies in nonferrous molten metal processing.

ALP80 Hydrogen Detector

ALP80 Clamshell Type Copper/AL Melt Hydrogen Detector ALP80 Main Application ALP80 is designed mainly to test gas content in copper melt. Built with high temperature resistance, it is also suitable for AL melt.This model can rapidly, within 5 minutes, complete a qualitative test on hydrogen/gas content status of copper or aluminum melt

Miniature Vacuum Degassing System

We report on the development and testing of a miniature vacuum degassing system designed for use in ladles, troughs, and furnaces. The system also generates an inert gas flow that can blanket the molten metal surface, thus degassing and preventing the reintroduction of hydrogen into the newly refined metal.
