Zirconia ceramic products e.g. atomizing nozzles

zirconia ceramic products

A range of zirconia ceramic based products are offered by Anderman Ceramics, which are manufactured to exacting standards with unique properties, putting our product at the forefront of performance.

Metering nozzles (flow control nozzles) are used for the continuous casting of steel as well as zircon atomizing nozzles for use in the Powder Metallurgy industry.

We also offer a range of crucibles based upon stabilised Zirconia. The properties of the finished product are determined by both the manufacturing method and the choice of the stabilising media.

Zirconia ceramic metering nozzles for continuous casting

Zirconia ceramics products e.g. atomizing nozzlesWe manufacture a comprehensive range of zirconia ceramic metering nozzles (flow control nozzles) used for the continuous casting of steel. Nozzles can be supplied in zirconia or zircon, either as solid nozzles or enclosed within a co-moulded outer body.

The composite nozzle method of manufacture allows a nozzle to be manufactured without the use of cement jointing. This system allows the use of a high performance zirconia ceramic insert with a lower grade outer material.

We offer ZPZ, ultra high performance zirconia nozzles. The performance of this type of nozzle is in some instances exceptional with many casting sequence records achieved. Advanced forming methods endow the nozzles with both high and uniform densities.

Properties of zirconia ceramic ZPZ nozzles

  • Long and Extended Casting Sequence Times
  • Controlled and Stable Casting Speed
  • Resistance to Oxygen lancing
  • Consistent Re-stranding
  • High performance
  • Wide range of products
  • Composite nozzles available
  • Quick change nozzle systems
  • Excellent erosion resistence

Atomizing nozzles

A range of zirconia / zircon atomizing nozzles are manufactured for use in the Powder Metallurgy industry. Atomizing nozzles are available in a wide range of shape and size, many to the requirements of individual customers.

Applications include the casting and atomization of Ferrous and Non Ferrous melts.

One of the principle features of Zircon / Zirconia atomizing nozzles are their close dimensional accuracy which promotes stable flow characteristics under the most arduous of conditions.

The addition of specially selected stabilising oxides provide high strength, excellent erosion resistance and minimise cracking due to thermal shock / rapid cooling.

Material grades for atomizing nozzles include

  • Yttria stabilised zirconia with excellent erosion properties. High temperature resistant, suitable for super alloy and nickel based alloys.
  • Ceria and magnesia stabilised zirconia with excellent thermal shock resistance. High temperature resistant, suitable for super alloy and nickel based alloys.
  • Zircon nozzle's with zirconia ceramic enhancement for low temperature, gas and water atomization of aluminium and copper alloys.
