Mono Block Stopper
Monoblock Stopper is used mainly for flow control on Molten Steel poured from tundish to mould. Monolithic Stopper is installed in the Tundish above the Sub Entry Nozzle and the gap between stopper head and Nozzle decide the throughput requirement of Molten Steel inside the Mould.
Argon can be blown into the tundish through argon inlet to prevent nozzle from Clogging ( specially designed feature wherever it is required we design and customise accordingly)
SPECIAL FEATURES:
o Facility for gas purging
o Anti oxidant properties
o Design and size as per customer’s requirement
o Clogging free casting for long sequence of casting
o Gas purging facilities to prevent alumina clogging (optional)
o Slag zone immersed part re-inforcement 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
