The test strategy confirms the time for cooling a chromised nickel ball from 8850c approx. to 3540c. the point when extinguished in 200 ml. Of test liquid in a non-attractive metal measuring utencil at a prespecified temperature.
An advanced timer, (with a determination of 0.01seconds) records the time taken for the ball to cool to curie temperature.
The timer is initiated by a photocell triggered by the hot ball, and is halted when the ball gets attractive (Curie Point more or less 3540c), and is pulled in by a magnet, tripping a switch.
The outcomes got from this test serve as an aide for selecting oil concerning quenching speed aspects, and furnish a measure of quenching speed (cooling rate).
