LMM have been supplied to world’s top steel manufacturer Arcelormittal, TATA Steel, EZZ steel etc. We do OEM for Concast and Danieli for a long time

Adopting excellent white corundum,flake graphite etc,and produced with scientific process and strict technology, which has 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 intothe inner hole of stoppers
6.The head of stopper adopts compound materials, which has better anti-corrosion property.
