Abstract
The utility model discloses a non-homoporous centrifugal pan for centrifuging glass fiber. Each hole in the side wall of the centrifugal pan is of a non-homoporous structure, and the diameter of each hole is gradually increased from bottom to top of the side wall of the centrifugal pan and is in a pyramid shape. High-temperature molten glass which rotates at a high speed in the centrifugal pan can be uniformly and gradiently thrown away along the holes in the side wall of the centrifugal pan in equilibrium to molten glass which is positioned on the side wall originally and has gradient temperature difference, so that the diameter of the glass fiber is distributed more uniformly and the fiber has better performance. In addition, the centrifugal pan has favorable high temperature resistance, oxidation resistance and mechanical performance under high temperature and long service life under high temperature.
