Anti-Swirling Tundish Nozzle for Vortex-Free Molten Steel Casting

Product Description

Anti-Swirling Tundish Nozzle for Vortex-Free Molten Steel Casting
 

Product Description

Shandong Sinorefractory New Materials Co., Ltd manufactures a comprehensive range of high performance Zirconia Tundish Metering Nozzles, 
used mainly in the continuous casting machine of steel billets.
Tundish Nozzles usually comprise a zirconia inner nozzle (often referred to as a "zirconia insert") with a lower grade outer body such as Alumina Bauxite, often called Outer Alumina Carbon material.
TUNDISH NOZZLE is used for continuous steel casting. 

SNREF Products used in Tundish can be offered to you as follows:

Tundish metering nozzle
Non swirling tundish nozzle
Tundish upper nozzle
Tundish lower nozzle
Tundish slide plate
Quick-exchange tundish nozzle
Ladle shroud
Subentry nozzle/ submerged entry nozzle
Monoblock stopper
This product is suitable for continuous cast tundish open cast steel.
The zirconium insert is made of high-purity zirconia, which is formed by high-pressure molding and sintering at high temperature.
The outer is made of corundum and high-quality aluminum vanadium.
It is formed by high pressure molding and baked at low temperature.
The two are bonded with corundum mud, and the product's corrosion resistance and thermal shock stability have reached the domestic advanced level, which can fully meet the needs of various billet continuous casting.

Application

SINOREFRACTORY Tundish upper nozzle .It is located within the tundish lining and conveys steel to the controlling exchangeable nozzle, which determines the steel flow.
The stationary nozzle must be capable of withstanding long sequence times.

SNREF Upper nozzle that incorporates a ultra-high insert.

The insert provides excellent erosion resistance and can provide extended casting sequence times.
The lower surface of the stationary nozzle is ground to exacting tolerances to ensure maximum surface contact between the two nozzle components. Tundish lower nozzle It is located within an assembly that is fixed to the bottom of the tundish.

The design of the exchangeable nozzle can vary according to the system manufacturer.

We supplying a range of zirconia inserts and composite nozzle designs for the exchangeable metering of steel.

Zirconia inserts can be supplied for on-site assembly into metallic holding blocks where cementing, grinding, size banding and on site drying are required prior to use.

It was manufactured by both cast process of fine grained alumina method or presse process. 

About Us

  Shandong Sinorefractory New Materials Co., Ltd (SinoRefractory) has beenfocusing on international marketing of flow control refractories in iron and steelindustry for 18 years.

  Started in year 2007, SinoRefractory is the second generation of refractoriesexport enterprise developed from Emei group, supported by one of China's largestproduction bases in functional refractory materials.

  Through years of development in the field of functional refractory materials,SinoRefractory aims at researching, marketing and exporting premium quality slideplates, nozzles, well blocks, purge plugs, nozzle filling sand, refractory castables,slide gate mechanism, tundish refractories to global markets.

  In 2021, SinoRefractory was spun off from Emei group.

  In 2022, in order to expand into broader product areas and commit to becominga high-end refractory materials supplier, SinoRefractory became an affiliated enter-prise of Sinosteel Luoyang Institute of Refractory Research.

  Following the establishment of this strategic collaboration, SinoRefractory hasachieved significant advancements in new product area development, technical su-pport and market expansion.
