摘　　要：In this paper,glass fibers were prepared by centrifugal-spinneret-blow(CSB) process.The molten glass got different flow rate from 390 kg/h to 270 kg/h by adjusting the electric current of platinum/10 rhodium alloy bushing.The diameter and microstructure of glass fibers have been investigated by scanning electron microscopy(SEM) and vertical optical microscope(VOM).The results indicated that the flow rate of molten glass was proportional to the diameter of glass fibers when the molten glass got main flow rate of 330 kg/h.The lower the flow rate was,the finer the average diameter was.In this paper, glass fibers were prepared by centrifugal-spinneret-blow （CSB） process. The molten glass got different flow rate from 390 kg/h to 270 kg/h by adjusting the electric current of platinurn/10 rhodium alloy bushing. The diameter and microstructure of glass fibers have been investigated by scanning electron microscopy （SEM） and vertical optical microscope （VOM）. The results indicated that the flow rate of molten glass was proportional to the diameter of glass fibers when the molten glass got main flow rate of 330 kg/h. The lower the flow rate was, the finer the average diameter was.
