Long Keter supplying a comprehensive range of zirconia inserts mainly used in continuous casting of steel billets. Zirconia inserts are also well known as zirconia nozzles.
The inserts ,which is known as zirconia nozzle 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.
Besides zirconia inserts, LONG KETER is also supplying a comprehensive rang of Atomising Nozzle to Powder metallurgy. In the atomisation process, nozzles controlling the flow of molten metal from the crucible while being bombarded with a high pressure jet of air, inert gas or water.A principle feature of all the nozzles is their close dimensional accuracy, which promotes stable flow characteristics under the most arduous conditions.
Key Features of zirconia nozzle series are
• Extended casting sequences
• Controlled and consistent casting speeds
• High resistance to oxygen lancing
• More consistent re-stranding
