Description

TECHNICAL FIELD

[0001] The utility model relates to glass fiber primary twist yarn technical field, especially a bushing correction tool. BACKGROUND

[0002] The bushing is one of main devices in glass fiber production, and is a groove type container. In the drawing process, the molten glass flows into the bushing, the bushing adjusts the glass liquid to the suitable temperature through the heating of two electrodes, and then flows out through the bushing mouth on the bottom plate and is stretched into continuous glass fibers by the high-speed rotating drawing machine at the outlet. The bushing is composed of PtRh10%, PtRh5% and Pt components, and adopts zirconium dispersion reinforcement.

[0003] The bushing mainly has seven structural components, the plug affects the temperature distribution of the bushing, and ensures the uniformity of the temperature of different regions of the bushing. The reinforcing rib improves the bearing capacity of the bushing, the bottom plate is distributed with the bushing mouth, and the flatness of the bottom plate determines the quality of the drawing. The inner diameter of the bushing mouth is directly proportional to the flow of the drawing production, the length of the bushing mouth is inversely proportional to the flow of the drawing production, and the inner diameter and the length of the bushing mouth jointly determine the drawing production efficiency. The flange and the side wall play a sealing role on the glass liquid and seal the gap between the bushing and the bottom plate brick.

[0004] The bushing temperature is a key factor affecting the drawing operation, and the fiber forming temperature has a certain range. The operation cannot be stabilized when being higher or lower than the range.

[0005] Main problems and defects:

[0006] 1. 80% of the bushings used in the present production are pure platinum (Pt) bushings, and the hardness of the bushing is relatively low. After the bushing is used for a long time, the abnormal situation of bushing deformation (i.e. the part of the bushing protrudes downward) may occur. Such phenomenon will cause the temperature of the bushing to be uneven, and affect the operation stability. INVENTION CONTENTS
