Tundish Upper Nozzle For Multiple Heats
The CNC quick-change nozzle,the service life is 45-108heats.The long-term service life if the product can reduce the labor intensity of the workers and improve the efficiency of steel drawing.The CNC upper nozzle can be customized according to your drawings.
Products Description
The Tundish Upper Nozzle for Multiple Heats is a high-performance zirconia refractory nozzle designed for continuous steel casting and long-sequence casting operations. It is developed for CNC quick-change tundish systems and is suitable for applications requiring stable steel flow, extended service life, and reduced nozzle replacement frequency.
With a service life of approximately 45–108 heats, depending on operating conditions, steel grade, casting parameters, and nozzle specifications, this long-life upper nozzle can help steel plants reduce maintenance requirements, lower labor intensity, and improve continuous casting efficiency.
The nozzle can also be customized according to customer drawings and specific tundish requirements.
Products Description
Key Features
1. Designed for Multiple Heats
The nozzle is specifically designed for long-duration continuous casting applications where extended service life is required. Its long operating life helps reduce the frequency of nozzle replacement and supports more efficient steelmaking operations.
2. High-Purity Zirconia Material
The working part of the nozzle is manufactured using high-purity zirconia-based refractory material. Zirconia provides excellent resistance to molten-steel erosion and is suitable for demanding continuous casting environments.
3. Press-Formed Composite Construction
The product can be manufactured as a composite nozzle with a high-alumina outer jacket.Compared with traditional cement-connected composite nozzles, the press-formed composite structure uses a zirconia insert together with a pressed outer jacket without cement pointing between the inner and outer components.
4. CNC Quick-Change Design
The CNC quick-change nozzle is designed for quick replacement applications in continuous casting tundishes. The quick-change configuration helps reduce maintenance time and labor requirements while supporting efficient continuous casting operations.The CNC upper nozzle can be manufactured according to the customer's drawings, dimensions, and equipment requirements.
Technical Specifications
The above values are the listed reference specifications. Product composition and grade selection can be discussed according to the customer's actual operating requirements.
