A Capacitance Probe for Measurement of Bubbles in Molten Metals.

Noncontact electrical resistivity measurement technique for molten metals

A noncontact technique of measuring the changes in electrical conductivity ~or resistivity! of conducting liquids is reported. The technique is based on a conducting drop that is levitated by the high-temperature electrostatic levitator in a high vacuum. This technique, which utilizes the principle of the asynchronous induction motor, measures the relative changes in torque as a function of tem...

Characterization of Gas Bubbles Injected into Molten Metals Under Laminar Flow Conditions

Veloci ty and volume m e a s u r e m e n t s of gas bubbles in jec ted into l iquid me ta l s under l a m i na r flow condit ions (at the or i f ice) have been achieved. A novel e x p e r i m e n t a l approach u t i l i z ing no i ses genera ted by bubbles was used to col lec t the n e c e s s a r y data. Argon gas was bubbled through t in, lead, and copper mel t s , and gas bubble fo rma t io...
