[0002] In the process of optical fiber production, raw materials need to be smelted and processed, which is mainly to ensure the quality and performance of optical fiber. Through high-temperature smelting, metal particles and other impurities in quartz raw materials can be effectively removed, thereby improving the optical performance and mechanical strength of optical fiber. At the same time, defects such as bubbles and cracks that may exist in the raw materials can be eliminated during the smelting process, improving the uniformity and stability of the optical fiber. During the smelting process, the chemical composition of the optical fiber preform rod can be adjusted by precisely controlling the temperature, atmosphere and other process parameters, which is crucial for preparing optical fibers with specific refractive index and physical properties.

[0003] However, the existing optical fiber raw material needs to be put into the smelting furnace during the smelting process, but the existing smelting furnace inlet usually adopts an open structure, which leads to the splashing of molten metal when the raw material falls into the molten metal, which obviously has a great safety hazard.
