Materials Refractory Metering Nozzle
Refractory tundish nozzles for continuous steel casting are made of zirconia and baddeleyite, formed by high tension and baked in high temperature when stablized by special technology. Different sizes and types of zirconia metering nozzles are designed and made according to users' different steel-making conditions and requirements.
The sizing nozzle is one of the key refractory materials for continuous casting of billet. It plays the role of controlling the flow rate of crystallization of molten steel and stabilizing the casting speed. The uniform and stable flow of molten steel through the sizing nozzle into the crystallizer is necessary to ensure the continuous casting. condition. Whether it is a zircon nozzle or a zirconium nozzle, it is often used in the process of expanding the diameter of the nozzle, bursting, falling off, and even some nozzles may be blocked, which may affect normal production.
Features of ladle collector nozzle for the bottom of steel ladle:
1.Low expansion, supprior resistance to erosion/corrosion and
thermal shock cycling.
2.Long and extended casting sequence times
3.Controlled and stable casting speed
4.Resistance to oxygen lancing
Our high purity and density ZrO2 tundish nozzle have the excellent
shock stability, strong errosion resistance, durable working time
etc features. Our tundish nozzles are different from the
one of Inida, UK, Germany, etc. origin. We have the high density of
5.4g/cm3, taking the special material and technology, automatic
production equipment, enough firing time, then excellent property
than them. For the tundish nozzle inserts, we have making testing
on 150tons ladle for 95% zirconia products, our tundish nozzle can
keep working 10-12 hours, even longer.
Our High performance 95% tundish Zirconia upper nozzle has the
high purity and density, excellent erosion, thermal shock
stability, crushing resistance, etc. feature. Tundish
nozzles are mainly control the steel liquid flowing amount
into the mould.
Physical & Chemical Index of Tundish Nozzle:
The structural principle of Tundish Nozzle:
The tundish nozzle is a combination of inner core and exterior. The inner core is made of stabilized zirconia and zircon sand, producing through molding machines and high-temperature calcination. The exterior is made of zirconium and corundum, producing through molding machines and low-temperature baking. Tundish nozzle is located at the bottom of the tundish, it's the channel of liquid steel to flow from the tundish into the crystallizer.
In casting steel tundish nozzle zirconia inserts are mainly used in successive-casting intermediary small square adobes, big square adobes, rectangle adobes and small board adobes.
