Focus on refractory production
Refractory for tundish
The long nozzle is a refractory material that connects the big bag and the tundish. The long nozzle has the functions of stabilizing the flow of the molten steel, preventing the oxidation of the molten steel, and preventing the splash of the molten steel. The CD series high-grade non-baked long nozzle successfully developed by Cheng Ding has the advantages of good thermal shock resistance, strong resistance to molten steel scouring and good slag resistance. At the same time, it is easy to operate and greatly improve working conditions. Can be promoted.
