The vacuum granulation technology improves the homogeneity and compact ability of materials, and enhances the products’ stability in use.
The use of Al2O3-C stopper tip has a superior performance in corrosion resistance to plain carbon steel and aluminum killed steel.
ZrO2 stopper tip with special surface treatment technology has strong adaptability of high-manganese and high-oxygen content of steel.
MgO-C stopper is dedicated to cast steel with Ca(Ca%≥20ppm).
ZrO2-C slag line has a superior performance in corrosion resistance
High standard Al2O3-C body materials have good thermal shock stability in use.
