Description
Product Description
Quick Change Plate Tunidsh Nozzle with Zirconium core CNC SYS120 SNREF
Shandong Sinorefractory New Materials Co.,Ltd manufactures a comprehensive range of high performance Zirconia Tundish Metering Nozzles ,
used mainly in the continuous casting 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 be called Outer Alumina Carbon material.
TUNDISH NOZZLE used for the continuous casting of steel.
SNREF Products used in Tundish can be offered to you as follow:
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
2. Zirconia insert
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.
SinoRefractory is the second generation of refractories export enterprise developed out of EMEI Group.Supported by one of China's largest production bases in functional refractory materials.

Lower Nozzles
(also referred to as: exchangeable nozzles, flying nozzles, shooting nozzles, quick-change nozzles, outer nozzles, inferior nozzles)
The lower nozzle is located within an assembly that is fixed to the bottom of the Tundish.
Once the nozzle wears out or the casting speed needs to be reduced the lower nozzle can be exchanged with either a new lower nozzle or a blank nozzle to shut the strand off entirely.
Lower nozzles must be erosion resistant to enable long casting sequences.
In addition to this lower must be able to withstand cold start practises or oxygen lancing.
Therefore a balance of erosion resistance and thermal shock resistance must be achieved.

Upper Nozzles
(also referred to as: Stationary nozzles, Superior Nozzles, Inner Nozzles)
As upper nozzles are located within the tundish lining, these nozzles are fixed and must be able to withstand long sequence times.
Therefore it is recommend that an ultra-high density zirconia
insert is used.
The zirconia insert provides excellent erosion resistance, allowing extended casting sequences.

Blank Nozzles
Nozzle blanks consist of a metal can and an Alumina body. No Zirconia inserts are used.
Blank nozzles are used to stop the flow of metal for a given tundish strand. Shutting the flow of metal to a certain strand will reduce the flow rate, slowing down the production and allowing other areas of the steel plant to catch up.
The blank can also be used as a safety mechanism; if the steel casting finds one strand to be problematic the strand can be shut almost instantly.
The strand can then be restarted by exchanging the blank with a new lower nozzle.
