Purging and Shape Refractory
Monolithic Lances
We manufacture monolithic lances for different applications,
such as Oxygen Lance, Argon Lance, Gas Stirring Lance and
Desulphurization Lance having the following properties:
o Ingredients homogeneousness, stable quality
o Superior corrosion and erosion resistance from metal and slag
o Excellent thermal shock properties
Monolithic Lances
Purging Plugs
VVEL offers pre-cast directional purging plugs equivalent to
IPV, GP II and GP III systems.
Slag Arresting Dart
Bulk density of this item is so designed that success rate is high and thus effectively arrest slag from going into the ladle during tapping of steel. Hence makes possible to tap Clean Steel and increases the useful capacity of steel ladle.
Purging Plugs, Darts & Tundish Nozzles
Purging Plug Housing Block and Ladle Well Block
Housing blocks are perfectly designed to suit actual shape and size of plug. We offers wide range of shapes / sizes of Ladle Well Blocks as per the requirement of customer with AI2 O3 percentage ranging from 45% to 90%.
Tundish Flow Modifier
Suitably designed as per Tundish configuration to reduce splashing and turbulence, minimizes slag emulsification and inclusion of non metallics.
Precast Blocks
Tundish Nozzles
These are highly suitable for open casting. We offer two types of Tundish Nozzles as mentioned below:
o Alumina-carbon Tundish Nozzle and Zirconia Insert
o Fully Zirconia Nozzles of different designs
These Zirconia Nozzles are very dense having AP < 5%, Bulk Density > 5.4g/cc and allows a steady flow of metal stream to the mould. Capable of withstanding a casting duration of 12 hours.
