Iron and Steel Industry - Intelligent Use of Alloys Brings Big Demand for High-Quality, Low-Cost Product

THE year 1936 has been an eventful one in the iron and steel industry. Renewed industrial activity has brought with it many new problems. These problems have generally involved the question of increasing capacity without sacrifice of economies and quality developed in the less active previous years. The nature of the iron ore used and the effect of its porosity and other physical characteristics on the capacity of the blast furnace has been reviewed by the U. S. Bureau of Mines. The whole question of handling raw materials and methods of charging furnaces has been intensively studied, with the result that capacity has been in- creased without affecting the quality of
