Problems solved by technology

[0005] At present, on the one hand, in the process of basalt wire drawing production, the bushing is subjected to a temperature as high as 1300°C. Under the above-mentioned high temperature conditions, the alloy strength and elastic modulus of the wire drawing bushing are very low, and the creep tends to increase. In this case, the bushing is easily deformed, and the middle of the bushing deformed at high temperature is sunken. On the other hand, the bottom of the brushed bushing disclosed in the above-mentioned prior invention patent is provided with ribs. Since the ribs are inwardly protruding Structure, under high temperature conditions, there will be high-temperature accumulation in the groove formed by the ribs located on the outside of the bottom plate, and the ribs that have been in the high-temperature accumulation state for a long time will accelerate the deformation of the bottom plate of the wire drawing bushing, and the scrapping frequency of the bushing is high. The production cost increases; in addition, at present, the number of holes in wire drawing leakboards at home and abroad is mostly hundreds of holes, and it is difficult to reach thousands of holes, which seriously affects the production efficiency of basalt fiber. With the increase of leak nozzles on the bottom plate, the high temperature deformation trend and deformation also gradually increased, thus limiting the number of nozzles set on the bottom plate of the existing wire drawing nozzle, thereby limiting the production efficiency of basalt fiber
For the above problems, there is no better solution
