Description

Technical Field

[0001] The utility model belongs to the technical field of split-type nozzle installation, and more specifically, relates to an installation device for a heated split-type nozzle. Background Art

[0002] The development of a split nozzle with mobile heating stems primarily from the urgent need to improve production efficiency and reduce costs in modern continuous casting operations in the iron and steel industry. In the continuous casting process, the submerged nozzle, a key component connecting the tundish and mold, has a lifespan that directly impacts the continuity of continuous casting and the quality of the molten steel. To extend the nozzle's lifespan and reduce the frequency of tundish changes, split nozzle technology has emerged. However, split nozzles require heating before use, primarily to ensure stable operation in the high-temperature, high-velocity molten steel environment. Heating not only maintains the nozzle's optimum temperature, preventing blockage caused by cooling and solidification of the molten steel, but also ensures the toughness and strength of the nozzle material, reducing material fatigue and damage caused by temperature fluctuations. Heating also helps maintain temperature uniformity within the nozzle, preventing deformation or damage caused by temperature variations. These measures collectively improve the continuity and efficiency of continuous casting, ensuring smooth molten steel flow and consistent product quality. To achieve these effects, the nozzle is typically heated to 350-400°C, or even higher. Currently, the nozzle is usually placed vertically during the heating process. After heating, the nozzle temperature is high, and the nozzle itself weighs dozens or hundreds of kilograms. At the same time, it is restricted by the baking device, making it very difficult to move, affecting the efficiency and continuity of continuous casting production. Therefore, there is an urgent need for a device that can move the split nozzle after heating.

[0003] In the prior art, Figure 1 As shown, the nozzle fork consists of a handle 1 and a fork head 2, with a total length between 1-1.5m. Figure 2 As shown, a baking oven 3 and nozzle 4 are commonly used. The nozzle 4 is inserted into the baking oven 3 for baking and heating. After heating, the nozzle 4 is removed by a nozzle fork. The heated nozzle 4 is usually removed manually using a nozzle fork and transported to the application area. Specifically, the fork head 2 of the nozzle fork is inserted into the gap between the bowl 5 of the nozzle 4 and the baking oven 3, that is, the fork is inserted into the neck 6 of the nozzle 4. The nozzle fork is then lifted horizontally upward with force to remove the nozzle 4 and move it to the intermediate tank area.

[0004] In the prior art, the nozzle fork is manually operated to move and install the heated split nozzle. To prevent the nozzle temperature from being too low, the split nozzle is often manually removed without closing the baking oven, which is a dangerous process. At the same time, it consumes a lot of manpower and has low efficiency in nozzle movement and installation. Moreover, the nozzle is easily damaged or destroyed due to uncertain factors such as manual operation techniques and physical strength. Utility Model Content
