Description
Technical field
The invention belongs to the manufacturing technology field of glass discharge nozzle, and in particular to a kind of glass discharge nozzle drawing module, glass
Glass discharging pipe manufacturing method and glass discharge nozzle.
Background technology
Frit forms melten glass, the stream of melten glass by the effect such as kiln, depositing reservoir, stirring pool, discharge nozzle
Go out by discharge nozzle to complete, because liquid level and the unloading position of melten glass have certain drop Δ h, this drop is formed
Gravitional force become melten glass outflow power.Melten glass held stationary in discharge nozzle flows at appropriate temperature
State, to obtain suitable flow.In the case of discharge nozzle is fixed, improves temperature and result in bigger flow；Typically
The temperature for improving melten glass is heated by electrode loop, and the effect of melten glass heating is generally by the thickness deviation of discharge nozzle
Determine, its regularity flowed is determined by the inwall quality of discharge nozzle.In production process, the limitation to melten glass temperature is to want
Ensure that the property of glass does not change, that is, ensure that split-phase or crystallization do not occur for glass；Regular limit is flowed to melten glass
System is to avoid producing shaping striped.
At present, the material of manufacture smelting glass discharge nozzle is preferably platinum, platinum-rhodium alloy, platinum yellow alloy, the yellow alloy of platinum rhodium
Have fusing point high Deng, manufactured discharge nozzle, creep resisting ability is strong, stable chemical performance, the features such as resistance to corrosion is strong.But by
Limited in the equipment and manufacturing process of manufacture, manufactured existing glass discharging bore and the precision of external diameter be not high, i.e. glass
The thickness deviation of discharge nozzle is big, and the inwall of glass discharge nozzle is second-rate；Therefore, glass is produced using existing glass discharge nozzle
During glass product, not only need frequently with the expects pipe that swaps out, and be easily caused glass phase-separating or crystallization, the glass product striped produced
A lot, yields is low.
The content of the invention
The invention provides a kind of glass discharge nozzle drawing module, it is intended to solves how to produce the precision of internal diameter and external diameter
The problem of higher and inwall better quality glass discharge nozzle.
The technical solution adopted for the present invention to solve the technical problems is：Glass discharge nozzle drawing module, including outside trombone slide
Mould and short core pull head；
It is the outer forming part of trombone slide, institute that the trombone slide external mold, which is provided with the minimum part of diameter on trombone slide hole, the trombone slide hole,
