Description of High Quality Refractories Tundish Monoblock Stopper Rod For Continuous Casting:
The monoblock stopper rod is a functional material made of refractory material, which is mainly used in the tundish. Monoblock 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 . The use of the stopper rod can reduce the occurrence of incidents and improve the quality of the billet. An argon blowing hole can also be designed in the integral stopper to blow argon to the submerged nozzle to prevent the nozzle from being blocked. 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 composites, we tailor-make monoblock stopper to suit specific customer requirements.

Product Features of Monoblock Stoppers
1.The vacuum granulation technology improves the homogeneity and compact ability of materials, and enhances the products’ stability in use.
2.The use of Al2O3-C stopper tip has a superior performance in corrosion resistance to plain carbon steel and aluminum killed steel.
3.MgO-C stopper is dedicated to cast steel with Ca(Ca%≥20ppm).
4.High standard Al2O3-C body materials have good thermal shock stability in use

Product Advantages of Tundish Monoblock Stopper Rod
The monoblock stopper rod has the advantages of good erosion resistance and erosion resistance, stable flow control during casting, tight closure after casting, etc..

Function of Tundish Monoblock Stopper Rod
1.Control the steel flow from tundish to mold.
2.In conjunction with a slide gate as an shut off device and to prevent slag vortexing at low tundish level.
3.To introduce argon into the pouring channel to prevent build up of clogging materials.
