The requirements for permanent layer, working layer, slag barrier wall, impact bucket and other types of intermediate ladle used in continuous casting vary depending on the usage location. Our company has the overall contracting capability for intermediate ladle and can develop and produce various amorphous refractory materials for intermediate ladle based on the smelting steel grade, smelting process and usage location. This can effectively extend the smelting time, reduce steel inclusions, and serve efficient and clean production.
Integrated contracting of refractory materials for intermediate packaging
Refractory materials for steelmaking
