This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ..."pile," or " faggot," which, if large, is tied by iron wire. The size of the pile depends on the size of the bars, etc., to be produced. It is raised to a full welding heat in the reheating or millfurnace, which somewhat resembles a puddling furnace, but is without a flue-bridge. Reheating furnaces working with gas, and provided with regenerators, are now commonly employed. When fully hot, the piles are withdrawn, and the bars welded together under the hammer or in a blooming-mill, the pile being afterwards reduced to a size suitable for rolling. It then passes to the mill train, which consists; as before, of two sets of rolls--roughing and finishing. The pile is cogged down to the required extent in the roughing rolls, and then passes to the finishing rolls to be converted into rounds. squares, angles, or any other form (section) required. The finishing train has chilled iron rolls, and the grooves are turned with great accuracy. Sometimes, instead of at once finishing, the billet, after rolling down, is cut up, and piled, reheated, and again rolled. It then forms No. 3, or best iron, while, if this is again piled and reheated, best best iron results. The oxide of iron formed in the reheating combines with the sand of which the bed is made and forms a slag, which flows out of the flue towards which the bed inclines. It. is known as flue cinder and mill-furnace slag. It consists of ferrous silicate, with a large excess of oxide of iron, and has a lustrous crystalline fracture. Light work is guided into the rolls by various devices, and is consequently known as guide iron. In rolling plates, plain rolls are employed. The billet is passed in one direction until the required width has been obtained, and then turned at...
