Product Description

Product Description

Mono-Block Stoppers in conjunction with Sub Entry Nozzle or Tundish Nozzle allow the Metering of flow of Steel in mould thereby allowing only desired flow in mould . This requirement necessitates many types of configuration on Stopper head which deliver the optimized results for flow .

Made with Isostatic Alumina Carbon or Magnesia Carbon or Zirconia Carbon composites, we tailor-make monoblock stopper to suit specific customer requirements.
