Excessively, the inadequate phenomenon of the heated dynamics of remainder occurs, to ensure that performance of the glass tube before spraying plating meets spraying plating standard.Its
In, it is in the wind between pipe and wire netting upper surface and is provided with flow-stopping plate, and be provided with flow-stopping plate multiple pod apertures so that upcast ventilation pipe
Pod apertures downward radiation of the high temperature air of middle effusion along internal diameter size gradual change, to realize the purpose of scattered thermal current, it is to avoid
Glass tube upper surface is directly heated again on the premise of carrying more heat transfer in itself, reduces glass tube scrapping in heating chamber several
Rate.
The present invention compared with prior art, has the following advantages and advantages：
A kind of softening method of electrothermal film glass tube of the present invention, in heating chamber, is concentrated to glass tube by multiple lower air conduits
Lower surface heated, and helped supplemented by upcast ventilation pipe so that the temperature in whole heating chamber reaches the softening temperature of glass tube
Degree, while ensureing that each several part of glass tube is heated evenly, it is to avoid local heating occur excessively, remainder dynamics of being heated is inadequate
Phenomenon occurs, to ensure that performance of the glass tube before spraying plating meets spraying plating standard；
