Supply pipe 21 supplies melten glass G2 to molten metal bath 311.Supply pipe 21 by such as platinum and platinum alloy extremely
Few one it is rectangular at.It is able to suppress reacting for supply pipe 21 and melten glass G2.Add moreover, can carry out being powered to supply pipe 21
Heat.
Supply pipe 21 has supply pipe main body 211 and protrudes outward from the end of downstream side of supply pipe main body 211 to diameter
Quadrangular ring-shaped flange.Upper wall 212, lower wall 213, left side wall 214 and the right side wall 215 for constituting flange respectively can be with confessions
It is integrally formed to pipe main body 211, it can also be individually formed and link with supply pipe main body 211.In the latter case, it supplies
Pipe 21 can also be formed by different multiple materials.Flange is preferably with platinum for main constituent material.But the composition material of flange
Material is not limited to this, is also possible to rhodium, iridium, molybdenum, tungsten, nickel, palladium, copper and their alloy etc..
Supply pipe main body 211 transfers melten glass G2.The downstream side opening portion of supply pipe main body 211 is located at than melting chamber
The position of the liquid level of melten glass G2 in 11a on the lower.Melten glass G2 is filled due to the pressure difference that gravity generates from fusing
10 are set to be transferred via melten glass handling device 20 to forming device 30.
Upper wall 212 protrudes upwards from the end of downstream side of supply pipe main body 211.It is able to suppress the upward of melten glass G2
The leakage of side.The up and down direction of upper wall 212 is having a size of such as 20~150mm.Upper wall 212 is than the melten glass in melting chamber 11a
The liquid level of G2 protrudes upwards.Upper wall 212 is formed as such as tabular.It should be noted that the shape of upper wall 212 is not special
It limits.
Lower wall 213 protrudes downwards from the end of downstream side of supply pipe main body 211.The up and down direction of lower wall 213 having a size of
Such as 20~150mm.Lower wall 213 is formed as such as tabular.It should be noted that the shape of lower wall 213 is not particularly limited.
Left side wall 214 and right side wall 215 are from the end of downstream side of supply pipe main body 211 in the horizontal direction each other to opposite side
It is prominent.It is able to suppress the leakage in the lateral direction of melten glass G2.The horizontal direction size and right side wall 215 of left side wall 214
Horizontal direction size be respectively such as 20~150mm.Left side wall 214 and right side wall 215 are respectively formed as such as tabular.It needs
It is noted that the shape of left side wall 214 and the shape of right side wall 215 are not particularly limited.

214 and right side wall 215, as long as but at least upper wall 212 among them.Moreover, upper wall 212, lower wall 213, a left side
The wall arbitrarily combined in side wall 214 and right side wall 215 can also be divided each other by crack.
Gate 22 adjusts the supply amount of melten glass G2 by going up and down in the downstream side of supply pipe 21.Gate 22 can also be with
The contact surface contacted with melten glass G2 is coated using platinum or platinum alloy.It is able to suppress the anti-of gate 22 and melten glass G2
It answers.
However, gate 22 due to relative to supply pipe 21 go up and down, form gap between supply pipe 21, to avoid
It is contacted with supply pipe 21.Due to forming the gap, thermal insulation is locally reduced.
Therefore, heating device 23 heats upper wall 212.Thereby, it is possible to inhibit between supply pipe 21 and gate 22
The solidification of melten glass G2 due to caused by the reduction of thermal insulation, can be such that gate 22 swimmingly goes up and down.Therefore, lock can be prevented
The breakage of door 22.
Moreover, being heated by heating device 23 to upper wall 212, it can be ensured that between upper wall 212 and gate 22
The mobility of gap and its neighbouring melten glass G2, is able to suppress the delay of melten glass G2, therefore is able to suppress melten glass
Heterogeneousization of G2, the generation for the disadvantages of being able to suppress brush line (striped).Its effect is especially in the alkali-free glass of LCD glass substrate
It is significant in the case where glass.This is because the alkali-free glass of LCD glass substrate is the high aluminium borosilicate glass of melting temperature,
For example, the gas componants such as boric acid are volatilized.
Heating device 23 has the electrode that electrified regulation is carried out to upper wall 212.Made using Joule heat and melten glass G2
The upper wall 212 of contact generates heat, therefore good to the transmission efficiency of the heat of melten glass G2 from heater, and melten glass G2's adds
The thermal efficiency is good.
