LD-Verfahren#

LD Process (Linz-Donawitz-process), one of the most important metallurgic developments of the 20th century for the production of steel out of pig iron by means of oxygen top blowing of technically pure oxygen (oxygen lance process). After years of preparatory work abroad, the VOeEST started a series of experiments in June 1949, headed by T. Suess, H. Trenkler, H. Hauttmann and R. Rinesch, which led to the opening of the first LD steel works in the world on November 27, 1952 (official opening on January 5, 1953). The world-wide acceptance of the LD process went hand in hand with the breakthrough in large-scale blast furnace technology and the transition from ingot casting to continuous casting. By 1990 about 60 % of raw steel world-wide was being produced by the LD process.
