Ladle Shroud long nozzle Chinese steelmaking

Product Description:

Description: 

Steelmaking long nozzle /refractory materials/refractory nozzles

steelmaking zircon nozzle   Zr content 94-95% , and nozzle with metal shell ,

can protect nozzle burst.the casting temperature normally at 1520-1580  ℃.

our zirconia cores temperature resistance up to 2000℃, density is 4.2g/cm3 .

Steelmaking tundish nozzle zircon core  contact face made a little big than other,effectively protect the nozzle using life.

tundish zirconia nozzles materials is alumina-zirconia-carbon .composed by Alumina-Carbon Shell, and zirconia core.

Graphic illustration:

1.Argon injection structure depending on customer specifications.
2.Ceramic glaze layer to prevent the material oxidation effectively.
3.Ceramic fiber blanket to prevent heat lost during casting.
4.High quality Al-C materials having high corrosion and thermal shock resistance.
5.High quality Zr-based composite to provide high corrosion resistance at the slag line.
6.Non-graphite based mased materials to meet the requirements of producing low carbon steel,silicon steel and high purity steel.

Manufacturing and QC

1.Raw materials blending

Independent raw materials blending center to assurestrict control of materials quality.

2.Shaping

Isostatic pressing technoloty,with as 1000 tons of pressure to assure the homogenous bulk density of each product.

3.Machining

To assure the uniform shape,dimension and dimension tolerance of each product.

4.X-ray defect inspection

To assure all products supplied to our customers without any defect and to prevent the un-countable feconomic loss for our customers.

5.Physical and chemistry analysis

To assure all products meet the physical and chemistry characteristics.

6.Packaging

The world-class for packaging to assure the safety transportation.
