Ladle Refractories Ladle Upper Nozzle
Description
Ladle Upper Nozzles controls the flow and flow direction of liquid steel by adjusting its internal structure and shape to ensure the uniform distribution and fluency of liquid steel in the pouring process and avoid the problem of poor flow and unequal distribution of liquid steel.
Ladle Upper Nozzles maintains its structural stability and mechanical properties at high temperature, is not easy to deformation and damage, and ensures the stability and consistency of liquid steel in the pouring process.
Ladle Upper Nozzles resist the corrosion of acid, alkali and other chemical substances in liquid steel and extend its service life.
