DESCRIPTION
High flow tundish lower nozzles are designed to allow a larger volume of molten steel to flow through the nozzle at a faster rate. These nozzles are commonly used in the production of larger steel castings, where a high flow rate is necessary to fill the mold quickly and efficiently.
One way to increase the flow rate of a tundish lower nozzle is to increase its diameter. By using a larger diameter nozzle, a greater volume of molten steel can pass through the nozzle at once, which allows for a faster flow rate. However, it is important to ensure that the nozzle diameter is not too large, as this can lead to issues with turbulence and inconsistent flow rates.
Another approach to increasing the flow rate of a tundish lower nozzle is to optimize the shape of the nozzle. By carefully designing the shape of the nozzle, it is possible to reduce turbulence and improve the flow rate of the molten steel. This can be achieved by using computer simulations to model the flow of the molten steel through the nozzle and iteratively refining the design until optimal performance is achieved.
It is also important to consider the material used to construct the high flow tundish lower nozzle. The material must be able to withstand the high temperatures and corrosive nature of the molten steel, while also allowing for a smooth flow of the molten steel through the nozzle. Alumina graphite and zirconia are commonly used materials for high flow tundish lower nozzles due to their high strength, thermal conductivity, and corrosion resistance.
Buy low cost high quality tundish nozzle. The tundish nozzle is used on the bottom of tundish, in conjunction with mono block stopper it controls the molten steel flow rate, stop the molten steel and adjust the flow direction. MGM Tundish nozzle has properties of good resistance to rushing scour, strong resistance to erosion, high flow-controlling stability.
