Tundish Covering Compound DAFEX 21
Product In Brief-
This compound is Specially formulated for use as a ladle insulating cover in conventional casting . It acts as best insulator and is specially recommended for duplex board. Being a neutral cover, it can be used for Supersilica as well as Magnesite board also.
DA FEX-21 ( SP ). IS an extremely efficient insulator, as soon as it is poured on molten metal, it expands almost five times and spreads immediately. If covers entire metal surface of the ladle and Tundish within few seconds. It prevents hard crest formation on the ladle wall and reduces skulling near nozzles. The heat losses are negligible. Ladle dumps out clean metal, with no metal adhering to the refractory lining. There is no need to superheat metal prior to handling, thus extending furnace and, ladle refractory life, while contributing to overall operating efficiency and improved metallurgical properties. The exothermicity is maintained throughout the process.
It is recommended to use this compound 2 kgs. per ton of molten metal.
The material is packed in 10 kgs. HDPE woven sack.
DAFEX-ZI is also an Alumina based neutral cover, recommended for duplex board & also it may be used in Super Silica d: Magnesite boards. This product doesn't have any expansion property but it also spreads immediately.
