ON THE JUDGEMENT OF STEEL INGOTS.

Abstract

It is ascertained with hundreds of large steel ingots that the briskness of making sparks from specimens taken from molten steel by dipping iron wire at the ingot head, or microscopic dirtiners of specimens thus taken, may be an exact guidance for the judgement of the properties of the ingot.
In the same occasion of dipping iron wire, we may often find floating solidified steel which after having grasped slags, goes soon into the lower portion of the ingot and causes the origin of harmful type of inclusions.
In this paper are described such method for the judgement of steel ingots and its practical applications for the improvement of the manufacturing Process of steel.
