Hisarna process is a smelting reduction process for producing liquid iron directly from iron ore fines iof and coal.It represents a new, potentially more efficient way of making iron and is being developed for substantial reduction of carbon emissions from the ironmaking process.Itis an initiative of ulcos ultra low co2 steelmaking consortium of.
The iron and steel industry has undergone a technological revolution in the last 40 years.In a relatively short time, the north american industry has observed the complete disappearance of basic open hearth processing, as well as the wide spread adoption of continuous casting and the near complete shift of long product production to the electric arc furnace sector.
Charge materials the ld vessel charge consist of molten metal, cold pig iron, steel scrap, calcined lime and dolomite, iron ore, fluorspar and pure oxygen of 99 purity.Hot metal ld process is often used to make soft steels for flat products with general requirements for extra low sulphur specification necessitated a constant reduction in sulphur contents of the final steel product.
