Our carolina activity of calcium carbonate production of stainless steel

Steel - Essential Chemical Industry


Lime (as calcium oxide or calcium carbonate), fluorspar (which helps to keep the hot slag as a fluid) and iron ore are added and these combine with impurities to form a slag. When the steel has reached the correct composition the slag is poured off and the steel tapped from the furnace.

Calcium carbonate - Wikipedia


Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid, but excessive consumption can be hazardous.
