Shin′gling.
(Iron-working.) The operation of removing slag, etc., from puddled iron. It is performed in a strong squeezer, or under the trip-hammer. Its object is to press out as perfectly as practicable the liquid cinder which the ball still contains; it also forms the ball into shape for the puddlerolls. A heavy hammer effects this object most thoroughly, but not so cheaply as the squeezer. The ball receives from 15 to 20 blows of a hammer, being turned from time to time as required; it is now termed a bloom, and is ready to be rolled or hammered; or the ball is passed once through the squeezer, and is still hot enough to be passed through the puddle-rolls. See trip-hammer; squeezer; steam-hammer.
