Product Description

Product Description

 CNC tundish nozzle quick change plate for steel continuous casting process

I. The CNC tundish nozzle plate is a crucial component on the tundish during the continuous casting process.
It is manufactured by computer numerical control (CNC) technology and has nozzles installed on it, which are used to control parameters such as the flow rate, flow velocity, and flow direction of molten steel from the tundish to the mold.

II. Main Structures and Components Plate body:
t is usually made of special alloy steel or ceramic materials that are resistant to high temperatures and abrasion to withstand the high temperature and scouring of molten steel. It has a certain thickness and strength to ensure that it will not deform or be damaged during use.
Nozzles: The nozzle is the core component installed on the nozzle plate. The material is generally refractory materials, such as zirconium-based or aluminum-carbon-based materials. The shape, size, and number of nozzles are designed according to different continuous casting process requirements. There are nozzles of different shapes such as circular, elliptical, and rectangular, and they can have single-hole or multi-hole structures.

III. Important Functions Flow control: By adjusting the aperture size, number, and open/closed state of the nozzles, the flow rate of molten steel from the tundish to the mold can be accurately controlled. This is crucial for ensuring the quality of the cast slab and the stability of the continuous casting process. Uniform distribution of molten steel: Ensure that the molten steel is evenly distributed within the mold, avoiding local overheating or uneven flow of molten steel. This can reduce defects in the cast slab, such as cracks and segregation. Prevention of molten steel oxidation and inclusion entrainment: A reasonably designed nozzle plate can minimize the contact of molten steel with air during the outflow process, thereby reducing the possibility of molten steel oxidation. At the same time, it can also reduce the chance of inclusions entering the mold and improve the purity of the cast slab.

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, quick changer cnc slide plate
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

 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.
