...Bogota, Sir William P. Hildred, 71, who has served as I.A.T.A. director general for 18 years, announced that he will retire after next year. His replacement: Swedish Diplomat Knut Hammarskjöld, 42, a nephew of the late U.N. Secretary-General. Sir William had a word or two about the SST. "I hope," he said, "that I shall not live to see the damned things...
Austria's famed LD process, for example, has enabled U.S. steelmakers to make steel more quickly and at a lower cost by lacing their furnaces with liquid oxygen. Last week U.S. Steel, the biggest U.S. steelmaker, announced that it is borrowing yet another technique from Europe-one that may revolutionize the U.S. steel industry...
Stora has built so many specialized machines and invented so many processes that it derives a substantial income from 120 licensing agreements with foreign countries. Its most notable recent achievement was the development of the Kaldo steelmaking process, which rivals Austria's famous LD process for making high-grade steel more quickly and efficiently...
...LD process, a water-cooled, 30-ft.-long steel lance is lowered through the top of the furnace, like a narrow straw into a thick-walled cream pot, and sprays compressed oxygen at supersonic speeds over the bubbling mix. With a roar that would drown out a brace of jet fighters, the oxygen burns off the sulphur, carbon and other impurities in the white mass. Because it takes barely half an hour to cook a batch of LD steel, v. eight hours in the conventional, open-hearth furnace, the oxygen process melts the costs of labor, power and fuel. Production...
Today a majority of the world's basic oxygen furnaces employ the LD process under license deals that furnish much of Austria's foreign exchange. And tomorrow, say steelmen, every new steel furnace will use some kind of oxygen process...
