High-performance Zirconia Insert Nozzle
Description:
The company developed tundish nozzle, sizing nozzle specially used in small billet caster tundish no plug stem gating system,and it is more suitable for small billet cc,tundish nozzle, sizing nozzle adopt the Special high-quality selection of raw materials, reasonable structure,strong erosion resistance, small change of the nozzle diameter and stable speed in the casting process, according to the customers' request, we can supply inlaying,compound and different types of nozzle products. Tundish nozzle, sizing nozzle.
Based on functions, tundish nozzle,submerged nozzle manufactured by our company are classified into plug-in type, hanging type and fast renewal type; and based on material quality, nozzles mainly classified into aluminum carbon, zirconium carbon and magnesia carbon. Tundish nozzle, submerged nozzle enjoys performances of purifying liquid steel, prevent liquid steel oxidation, with good liquid steel washing resistance and erosion resistance. Tundish nozzle, submerged nozzle
Sizing nozzle can be divided into two types according to dimensions: one is mosaic sizing nozzle series according to national standard sizes; the other one is heterosexual tundish upper nozzle series based on the drawings offered by the use of factory. After long-term production and actual use, this product has good thermal shock resistance, corrosion resistance, and low expanding rate, without bias, casual flow, burst, and drift tube phenomenon. The product types in high-middle and low range of different levels can meet the needs of different users.
Advantage:
The Tundish Nozzle has the properties of high refractoriness,good resistance to shock,good resistance to erosion,bearing rushing scour , high flow-controlling stability and long life etc.
Application:
They are mainly used in the basic zones of small billet,big billet, rectangular billet.etc.
