By the mid-1930's, Germany had become the leader in steel technology; in 1950, Austria developed the basic oxygen furnace.

In the third step, the iron is dumped into an oxygen furnace and combined with a small portion of scrap steel.

The molten iron then goes through a process similar to the oxygen furnace in conventional steel plants.

Basic oxygen furnaces and electric arc furnaces have largely replaced all previous ones.

Today's basic oxygen furnaces produce steel at a much faster rate than old style open hearth furnaces.

A modern method for decarburizing the pig iron and refining it into steel is basic oxygen furnace.

However, most modern steel plants use what's called a basic oxygen furnace to create steel.

It requires further treatment in a bessemer converter or basic oxygen furnace to produce steel or wrought iron.

Silicon carbide, dissolved in a basic oxygen furnace used for making steel, acts as a fuel.

A modern converter called basic oxygen furnace uses pure oxygen instead of air.
