Excerpt from Proceedings of the Eighteenth Annual Meeting Held at Atlantic City, New Jersey, June 22 26, 1915, Vol. 15: Part II. Technical Papers Steel specimens ranging in size from 12-in. Round to 2-in. Round were brought to four furnace temperatures, 1000, 1200, 1400 and 1600 Degrees F. Continuous records were kept showing the rates Of heating Of the various specimens and the relation in temperature between the furnace gases, the surface of the specimen, and various points in its interior. It was found that the specimens assumed the furnace temperature in less time as the temperatures increased (except when the furnace temperature was slightly above the transformation point); that the tempera tures throughout the interior Of the specimens equalized them selves rapidly; that a contact thermocouple may be used to show when the specimen has reached the furnace temperature throughout its mass; and that a contact couple may be used to show when the specimen passes through its transformation point.
