The Pickling Process CSI's pickling line started up in late 1994, and typically processes two out of every three coils produced at the Hot Mill. Its primary function is to remove the thin layer of oxidized iron, or scale, that forms on the surface of the steel at the temperatures employed during hot rolling.
Lime also has important uses in secondary refining of steel and in the manufacture of steel products. Electric Arc Furnaces. In electric arc furnaces, scrap iron and steel, scrap substitutes such as DRI and HBI, pig iron, iron ore, and beneficiated iron ore are placed in a furnace and melted by the use of heat from an electric current.
Continuous casting has several advantages but it is also a process that needs distinct resources. This is the reason why this process is employed only in industries that require high yield of steel cast. The metal is first liquefied and poured into a tundish, which is a container that leads to the mold that will cast the steel.
Ladle refining of liquid metal is a proven technology to produce high quality steel. A Ladle Refining Furnace is used to raise the temperature and adjust the chemical composition of molten metal. Without LRFs, higher tap temperatures are normally required from steel making furnaces due to heat losses during refining with conventional ladles.
Steel Making / Technology / Projects Products and services span the entire lifecycle of the steelmaking process from the frontend phase of a project to production, implementation and .
Feb 18, 2015· Once the desired steel composition and temperature have been achieved in the furnace, the tap hole is opened, the furnace is tilted, and the steel is poured into a teeming ladle for transfer to the secondary steel making unit. During the tapping process, ferro alloy additions are made based on the bath analysis and the desired steel grade.
