A practical treatise of foundry irons

A PRACTICAL TREATISE ON FOUNDRY IRONS: COMPRISING PIG IRON, AND FRACTURE GRADING OF PIG AND SCRAP IRONS ; SCRAP IRONS ; MIXING IRONS ; ELEMENTS AND METALLOIDS ; GRADING IRON BY ANALYSIS ; CHEMICAL STANDARDS FOR IRON CASTINGS ; TESTING CAST IRON ; SEMI- STEEL ; MALLEABLE IRON ; ETC., ETC. Preface: This volume has been prepared at the earnest request of many founders seeking practical information on FOUNDRY Irons and their manipulation in the production of the various lines of castings. It has been the aim of the author to present, in a condensed form, only such matter as is of practical value to the founder and to eliminate as far as possible all theories that have not been established as principles and all laboratory experimental work that has not been fully demonstrated to be useful in actual foundry practice.
