Summary
[edit]DescriptionAmerican Society of Mechanical Engineers 1985 Plaque.jpg |
English: American Society of Mechanical Engineers 1985 Plaque. Oxygen-Process Steel-Making Vessel McLouth Steel Products Corporation. Trenton, Michigan 1955 Inscription: This is one of the three original 60-ton vessels by which the basic oxygen process of steel making was introduced into this country from Austria, where it was invented. It heralded the first new technology in fifty years that became the basis of a major process for steel production throughout the world. In this process a water-cooled lance injects a jet of high-purity oxygen into the bath of molten iron. Various chemical reactions take place to produce a quality, low-nitrogen steel at a ton-per-hour rate nearly three times that of the open-hearth furnace. |
