2013/11/29· Deoxidation, desulphurisation and inclusion modifiion are some of the essential features in secondary steel refining through injection of calcium alloy in the form of a cored wire. It is imperative that the filling material must be consumed by the melt to the maximum extent in order to make this cored wire alloy addition cost effective and efficient.
Granulometry data is presented for various types of Calcium products found in the supply chain. Data has been collated from companies, which use Calcium for a variety of appliions, including: production of calcium injection wire; production of alloys; deoxidation and desulfurisation of steel, iron and, non-ferrous metals; and the like.
Calcium Silicide cored wire is source of Calcium for steel industries, which is used for Deoxidation, Desulphurization and Inclusion modifiion. Cored wire is prepared by, high grade of CaSi granules or powder, which is filled in U shaped steel sheath (Made of high quality of cold rolled steel strip), and this U shapes steel sheath is closed tightly, so called overlapping craft, with help of
