Long Keter supplying a comprehensive range of zirconia inserts mainly used in continuous casting of steel billets.
The inserts ,which was known as LKZN series, is magnesia stabilised & high density,can impart excellent erosion resistance even in the most severe casting environments.
Consistent casting speeds are achieved and the products have a high resistance to oxygen lancing.
