What is Linz-Donawitz process?

In metallurgy: Ferrous metals. The Linz-Donawitz process, invented in Austria shortly after World War II, used oxygen supplied as a gas from a tonnage oxygen plant, blowing it at supersonic velocity into the top of the molten iron in a converter vessel.

What are the processes of manufacture of steel?

Today there are two major commercial processes for making steel, namely basic oxygen steelmaking, which has liquid pig-iron from the blast furnace and scrap steel as the main feed materials, and electric arc furnace (EAF) steelmaking, which uses scrap steel or direct reduced iron (DRI) as the main feed materials.

What kind of steel is a LD converter made of?

3.    LD converter is a welded construction of non-ageing steel plates (8mm), the height of the vessel varies from 7-10m. L.D converter has a basic lining of magnesite bricks (permanent lining) and Dolomite bricks (working lining).

What do you need to know about LD process?

LD process is a refining process which is carried out in a LD vessel (or LD converter/BOF). 3.    LD converter is a welded construction of non-ageing steel plates (8mm), the height of the vessel varies from 7-10m. L.D converter has a basic lining of magnesite bricks (permanent lining) and Dolomite bricks (working lining).

How is the hot metal converted into steel?

The hot metal is converted into steel through a steelmaking process called the LD process. The steel is cast into slabs, which are then rolled into hot rolled coils in the Hot Strip Mill & Thin Slab Caster. Some of the hot rolled coils are further rolled into cold rolled and galvanisedcoils in the Cold Rolling Mill.
