Title:
SYSTEM FOR DETECTING INCLUSIONS IN MOLTEN METALS
Document Type and Number:
WIPO Patent Application WO2001075183
Kind Code:
A3
Abstract:
The present invention relates to systems of methods of detecting and measuring inclusions in liquid metals. More particularly, non-metallic inclusions having a conductivity level different from the liquid metal melt are forced to migrate and are collected on a measurement surface using electromagnetic Lorentz forces. The inclusions and their concentrations are detected at the measurement surface using either an electrostatic detection system or an optical detection system.
