Ferro Silicon Calcium Cored Wire: Chemical Composition of Casi Powder
Product Description
Calcium Silicide cored wire is souce of Calcium for steel industries, which is
used for Deoxidation, Desulphurization and Inclusion modification. 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
equipment. The encapsulated Calcium Silicide in steel sheath (called cored
wire) is injected into the steel melt with help of wire injection system with the
purpose of high recovery of Ca in steel than the virgin Ca / CaSi lumps
addition into the ladle. The powder specification of Calcium siliside, which is
used in cored wire, strip specification, & wire characteristics, is given below:

Packing
Packing in flipping cage and mounted on
wooden / mild steel pallet and strapped with
pallet horizontally or vertically. All coils are
wrapped in stretch film & palletized
Coil Identification
All coils are colour coded and fixed with a detailed
sticker clearly displaying details such as coil no.,
powder content, strip weight, gross weight density &
length. A fluorescent sticker displays the name of the
product in bold letters on the outer diameter of the
coil.
Handling
No metal sling, chain or rod is to be used across the
ID of the coil for handling as it may damage the coil.
Use only polyester, synthetic slings, fork lift/tractor
to handle the coil. The pallet is an integral part of the
coil and it is to be removed till the coil is consumed.
Shelf Life
Follow the shelf life period specified by MINEX
