RI 5120 Special Pig Irons For The Pacific Northwest ? Summary

Because of the absence of an iron-producing industry, the Pacific Northwest is working under an economic handicap. This is particularly apparent in the gray-iron-foundry industry because of the high price of pig iron imported from foreign sources or shipped in from producing ?areas within the United States. The high prices and sometimes short supply of ferrous metal products has put a brake on industrialization, which has been only partly compensated by the availability of cheap electric power. The economic condition of the gray-iron-foundry industry could be improved by establishing a small iron-producing industry based on the locally available ores. Moreover, establishing a local iron smelter would create a market for resources now dormant. Low-grade ores of manganese, chromium, and nickel would become usable in industry when combined with the iron ore from Scappoose. Pig iron produced in even limited quantities would level out the fluctuation in supply. The ore deposits, being small, would not supply enough pig iron to satisfy the entire demand. This condition necessitates designing special pig irons that will carry abnormally high proportions of scrap in the cupola charge.
