Apparatus for the detection and measurement of suspended particulates in a molten metal |
摘要 |
An apparatus and method for the detection and measurement in a molten metal sample of suspended particulates comprises a container having a composite wall including concentric electrically conducting outer and inner walls (10) and (12) and a disc (14) of refractory material having a passage (16) of predetermined size therethrough providing communication between the inside and outside of the container. In use, molten metal is pumped through the passage (16) so as to establish a current path from the inner wall through the passage to the out wall. A current is passed along the current path, and voltage changes are measured as indicating passage of suspended particulates through the passage.
