Book excerpt: Excerpt from The Library of the University of California Santa Barbara College Foundry work is the name applied to that branch of engineering which deals with melting metal and pouring it in liquid form into sand molds to shape it into castings of all descriptions. In the manufacture of modern machinery three classes of castings are employed, each one having its individual physical properties, such as strength, toughness, durability, etc. These castings are made from gray iron, copper alloys, i.e., brass, bronze, etc., and mild steel. By far the greatest number of castings made are of gray iron, that is, iron which may be machined directly as it comes from the mold without any further heat treatment. The main purpose of this book is to explain the underlying principles involved in making molds for gray iron castings, and the mixing and melting of the metals for such castings. There are two other forms of iron castings. These are chilled iron, used for rolling mill rolls, car wheels, etc., and malleable iron, used for certain lines of builders and manufacturers hardware. These are not dealt with in detail because they are rather specialities in the trade, whereas there are few towns of importance in this country in which there is no gray iron foundry. The chapters on brass founding and steel casting will emphasize only those features of the methods used which differ from iron foundry practice. The chapter on shop management is intended to set students thinking on this subject; because the whole trend of modern shop practice is toward specialization and system in handling every department of the work, in order to increase efficiency and reduce cost. Iron Molding There are four main branches in gray iron molding: green sand work, core work, dry sand molding, and loam work. Green sand molding is the cheapest, quickest method of making the general run of castings. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
