| Abstract: | The damage of the stopper caused by free-cutting steel includes the erosion for the material by element Mn and O in the molten steel besides eroding. Taking fused magnesia, flake graphite and nitride as main raw materials, adding composite high temperature antioxidant and preventing the oxidation of carbon by stages protecting, the refractory for stopper with excellent high temperature oxidation resistance was developed. Applications showed that the monolithic stopper was used continuously for six heats in casting free-cutting steel 12L14 and the longest casting time was 6.5 hours. |
