Tundish Nozzle Introduction: Tundish nozzles usually comprise a zirconia inner nozzle (often referred to as a “zirconia insert”) with a lower grade outer body such as Alumina, Zircon or Bauxite. Tundish Nozzles are an integral part of Continuous Steel Casting process. The design of tundish nozzles vary according to the system manufacturer or the individual needs of the steel plant. Tundish nozzle is a combination of inner core and exterior. The inner core is made of stabilized zirconia and zircon sand, producing through molding machines and high-temperature calcination. The exterior is made of zirconium and corundum, producing through molding machines and low-temperature baking. Tundish nozzle is located at the bottom of the tundish, it's the channel of liquid steel to flow from the tundish into the crystallizer.  Tundish Nozzle Advantages: 1. Fast sliding, accurate, no bias current, steel leakage;2. Good corrosion resistance, no obvious expanding, long service life, no bias current and dissipation;3.

Tundish Dry Vibration Mix Introduction: The tundish dry vibration mix is composed of refractory aggregate, powder, sintering agent and admixture. Without the addition of water or liquid binder, only by vibration, a dense and uniform monolithic refractory raw material can be formed. When heated, tundish dry vibration mix is made tough by a thermosetting binder or a ceramic sintering agent. Tundish dry material is an unshaped refractory material (tundish working lining) made by vibration molding without adding water and liquid binder. The dry material is dense and uniform, and the demoulding strength is generated after low temperature heating.  Tundish dry vibration mix's characteristics are: This kind of material is easy to flow under the action of vibration force, and the powder can fill the tiny pores between particle accumulations even under the action of very small vibration force, and obtain a dense body with higher filling density. In use, it is heated to form a working surface with a certain strength. However, part of the non-working face is still unsintered and presents the original densely packed structure. This structure helps to reduce the stress caused by expansion or contraction; helps to hinder the spread and extension of cracks; helps prevent the intrusion of molten metal, and facilitates unpacking and cleaning. This material is constructed on the construction site by vibration method, which is easy to construct, short in construction period, does not require maintenance and baking, and can directly raise the temperature quickly to make the working layer sintered and put into use.  Tundish Dry Vibration Mix Advantages: Strong resistance to molten steel and slag, convenient construction, long service life, waterless construction reduces the chance of secondary oxidation of molten steel in the tundish. The tundish working lining made of tundish dry vibration mix has been widely used in major steel plants because of its convenient construction, short baking time, good slag resistance, good insulation effect, low energy consumption, and simple construction equipment. Advantages of dry vibrating material construction:(1) The construction process is convenient and fast(2) Reduced labor intensity(3) Improved construction environment(4) No dust, no irritating gas, no pollution to the environment

The nozzle brand can be set according to the different steelmaking environment and use requirements of users. The service life and performance of the sizing nozzle refractories are very critical. Zirconia sizing nozzle is widely used in billet continuous casting tundish. The performance of the nozzle directly affects the length of continuous casting time. The sizing nozzle is the nozzle brick in the sliding nozzle device adopted by the steel mill when casting the billet. Zirconia nozzles are highly corrosive to molten steel and molten slag. The nozzles are usually made of higher purity zircon, CaO stabilized ZrO2 and industrial zirconia. Zirconium Sizing Nozzle Advantages: Zirconium sizing nozzle is mainly used for continuous casting of tundish billets, blooms, rectangular billets, and small slabs. Sizing nozzle is mainly used for continuous casting of tundish billets, blooms, rectangular billet and small plate, which is with following characteristic: 1.High refractoriness 2.Good thermal shock performance3.Erosion stability 4.Small diameter expansion5.Long service life Zirconium Sizing Nozzle Effect:The sizing nozzle, as the key refractory material for billet continuous casting, plays a role in controlling the flow of molten steel, determines the drawing speed of the billet in continuous casting, and is a necessary condition to ensure the normal operation of continuous casting. It is called continuous casting function. Refractory materials. In addition to preventing pouring bursting, blockage and falling off, the sizing nozzle must not be expanded too fast to meet the requirements of long-term casting. The production process of the sizing nozzle plays a vital role in its performance. The process parameters such as the particle gradation of raw materials, mixing time, molding pressure, drying method and firing system will all affect the performance of the nozzle.

Long Nozzle Introduction: With a special clamping device, the long nozzle is fixed between the ladle and the tundish to isolate the contact between the molten steel and the air to reduce the secondary oxidation of the molten steel, improve the purity of the molten steel, and prevent the steel from splashing. The use of a non-preheated long nozzle has the advantage that it can be directly installed and used without preheating, thereby saving fuel costs and reducing the labor intensity. Long Nozzle Advantages： The long nozzle has strong adaptability to steel grade and good corrosion resistance. The new designed long nozzle structure realizes the immersion pouring, which effectively alleviates the serious entrapment and air suction during pouring. The invention of long nozzle started from the demand for the protection of molten steel pouring. Its use played a good role in preventing the secondary oxidation and slag entrapment of molten steel, and played an important role in the development of molten steel continuous casting. For continuous casting operations, the long nozzle is of great significance, not only related to its steel-forming efficiency, but also related to the yield. Therefore, for the shape of the long nozzle, the choice of material is equally important. Compared with the submerged entry nozzle, the long nozzle also needs to have many advantages such as crack resistance and corrosion resistance.
