Linz Donawitz

Linz-Donawitz process See basic-oxygen PROCESS. 

L-D Process. A process for the production of steel by the oxygenblowing of molten iron held in a static vertical vessel. The latter is lined with tarred or fired dolomite refractories dead-burned magnesite is also sometimes added to the batch. The process was first used in 1952, at Linz, Austria, and L-D stands for Linzer Diisenverfahren, i.e. Linz Nozzle Process (not Linz-Donawitz, as is commonly believed).
