Ladle upper nozzle
For the steel mill, the service life of the water inlet will have an impact on the service life of the bottom, and the service life of the bottom directly affects the comprehensive age. According to the above situation, our company adopts the latest matrix optimization technology and the closest packing. The theory has successfully developed the longevity life ladle upper nozzle. The product has excellent thermal shock stability, outstanding anti-oxidation ability and strong anti-scour ability.
