A full-automatic-Jominy test apparatus has been developed, the characteristics of which are as follows :
(1) Adoption of the smaller test specimen (conventional : 25 mm new-type : 10 mm), which enables application of Jominy test method to the thinner products so far extremely difficult.
(2) Adoption of induction heating method, resulting in rapid heating rate so far unattainable.
(3) Adoption of the present control system, by which desired heating pattern simulating the actual heating conditions can be obtained.
(4) Adoption of the full-automatic sequence control system, by which end-quench test for harden-ability of steel can be carried out without an operator.
In this article, the details of development and characteristics of the new-type Jominy test apparatus are shown.
