Ladle Shroud
Ladle Shroud
The function of tundish ladle shrouds is to connect the ladle and the tundish, to transport the molten steel from the ladle to the tundish, and to fulfill the purpose of protecting the casting and preventing secondary oxidation of the molten steel.
According to customers’ requirements, preheating or non-preheating related ladle shrouds can be customized, with the characteristics of high temperature resistance, corrosion resistance, long service life, etc.
