Continuous Casting Refractory | Total Tundish Management

Continuous Casting Refractory (CCR)

Continuous Casting is a process in which Molten Steel (chemical composition has been adjusted by secondary refining) is solidified in water cooled copper mould.

In the Continuous Casting of Steels, Tundish is a Buffer Refractory Lined Vessel, which is located between the ladle and the CC mould. The Tundish serves the purpose of a reservoir and a distribution vessel. Over the years, innovative changes have taken place in CC Tundish.

We started manufacturing Continuous Casting Refractory (CCR) from the year 2003, which includes viz., Ladle Shroud (LS), Submerged Entry Nozzle (SEN), Monoblock Stopper (MBS), Tundish Nozzle (TN) etc.
We also carry out Total Tundish Management (TTM) wherein we are required to supply all the items involved in a Tundish, including technical services and applications at site.

SPECIAL FEATURES:
o Refractory having Antioxidant properties.
o Design and size as per customer’s requirement.
o Clogging free casting for long sequence of casting.
o Argon Gas purging facilities to prevent alumina clogging (optional).
o Slag zone immersed part reinforcement with special material for long life.
o Argon sealing purging arrangement can be provided on customer’s request.
o Wide range of formulation for withstanding oxidation and long sequence casting.
o Different assembly methods for assured security even in long sequence casting.
o We manufacture Silica free Oxy-bore ladle shroud for less corrosion and long
sequence casting.
