Adopting excellent white corundum, flake graphite etc,andproduced with scientific process and strict technology, whichhas perfect anti-thermal shock,anti-corrosion，anti-erosionand anti-oxidation properties.
1.Gasket
2.Steel nuts connection prevents the stoppers from coming off.
3.The monolithic body is Al-C materials with perfect anti-thermal shock property.
4.Anti-oxidation coating prevents the products from oxidation .
5.Porous plug, even ventilation, to stop the molten steel into the inner hole of stoppers
6.The head of stopper adopts compound materials, which has better anti-corrosion property.
