At the basis of advanced technology we built our new production line for black con-casting refractory products with advanced equipments, the capacity is over 5000 tons/ year. We have experienced technicians and strong R&D team, excellent after-sale service. Our products are supplied to many domestic steel plants and exported to USA, Canada, Japan, Egypt, Turkey and etc.. Main products are as follows:
Ladle shroud：
a: Long service life and Non-preheating LS;
b: Ladle shroud with argon/ without argon;
c: Big bell canopy shroud.
