However, surround supply pipe around electroforming brick by be integrally formed a component constitute in the case of, when
When the environment temperature of supply pipe rises in glass manufacture, electroforming brick produces rupture because of thermal deformation sometimes.In addition, by electroforming brick
In the case of being formed integrally as the shape surrounded around supply pipe, there are the processing difficulties of electroforming brick, expend very much and make
The problem of cost.
Therefore, in order to eliminate these problems, for example, it may be considered that combine the electroforming brick of the fairly simple shape such as tabular
And surround around supply pipe.
However, in this case, therefore electroforming brick only turns into unstable construction by simple combination.Therefore, if obstructed
Some way limitation electroforming brick is crossed, then there is the possibility that electroforming brick offsets and larger gap is formed between adjacent electroforming brick
Property.If forming such gap, easily become unstable in the temperature of the melten glass of the internal flow of supply pipe, can also lead
Cause bad as the system of the glass of final products.
On the other hand, the thermal conductivity of electroforming brick is higher, and the outer surface of electroforming brick turns into high temperature in glass manufacture.Therefore,
In the case where the outer surface directly contact of metalwork and electroforming brick is made to limit electroforming brick, exist metalwork produce thermal deformation and
The problem of electroforming brick cannot reliably be limited.
The content of the invention
The invention problem to be solved
In view of the foregoing, problem of the invention is reliably to limit to be combined in the way of surrounding around supply pipe
Electroforming brick, realize the stabilisation of glass manufacture.
Scheme for solving problem
The glass manufacturing apparatus involved in the present invention completed to solve above-mentioned problem are characterised by possessing：For
To the supply pipe of the noble metal of melten glass；The electroforming brick combined in the way of surrounding around supply pipe；And from outer
The limiting mechanism of lateral spacing electroforming brick, the contact site contacted with the outer surface of electroforming brick of limiting mechanism is formed by heat-resistant component.
According to this structure, the contact site of limiting mechanism is difficult that hot change occurs because of the heat of the electroforming brick as high temperature
Shape, the restriction state stabilization of electroforming brick.Therefore, it is possible to pass through limiting mechanism, in glass manufacture, also reliably lasting limitation is electric
Casting brick, additionally it is possible to contribute to the stabilisation of glass manufacture.
Preferably, in such a configuration, heat-resistant component has lower thermal conductivity compared with electroforming brick.
So, the heat of the electroforming brick as high temperature stopped by heat-resistant component, is difficult the contact site to limiting mechanism
Part transmission in addition.Therefore, it is possible to form the contact site of limiting mechanism for example, by the low cheap metalwork of heat resistance
Part in addition.
Preferably, in such a configuration, for an outer surface for electroforming brick, what is do not contacted with heat-resistant component exposes
The area of non-exposed area of the area in region than being contacted with heat-resistant component is big.
That is, the general thermal conductivity of electroforming brick is high, the heat release of the melten glass for promoting the internal flow in supply pipe.So
And, the situation that the thermal conductivity ratio electroforming brick of heat-resistant component is low is more, if covering the major part of electroforming brick by heat-resistant component, can
The heat release of melten glass is hindered, there is the viscosity possibility for being difficult to maintain desired.It is preferred, therefore, that as described above, adopting
It is bigger than the area of non-exposed area with the area for making the exposed area in an outer surface for electroforming brick, so as to be difficult because of heat-resisting structure
Structure as the heat release of part obstruction melten glass.
In such a configuration, it is also possible on an outer surface for electroforming brick, it is spaced with along the circumferentially spaced of supply pipe
Mode be configured with heat-resistant component.
So, the area that heat-resistant component is contacted with the outer surface of electroforming brick can be reduced, and easily by heat-resisting structure
Part is configured in the optimal position needed for the limitation for carrying out electroforming brick.
In such a configuration, electroforming brick can also be combined into square tube shape, and limiting mechanism is from corresponding with each face of square tube shape
Four direction limitation electroforming brick.
So, can reliably be limited from different four directions (for example, upper and lower and left and right) and be combined into square tube
The complete cycle of the electroforming brick of shape.
In such a configuration, glass manufacturing apparatus can also be configured with what is set in the way of surrounding around electroforming brick
Encasing, limiting mechanism fixes electroforming brick relative to encasing.
So, electroforming brick can simply and reliably be limited.
In such a configuration, encasing can have multiple opening portions.
So, the gas of the inner space of encasing is efficiently arranged by opening portion to the exterior space of encasing
Go out.Therefore, even if being configured with encasing, it is not easy to heat release of the obstruction in the melten glass of the internal flow of supply pipe.
In such a configuration, heat-resistant component can be covered at least a portion for the seam formed between electroforming brick.
That is, the seam portion in electroforming brick produces position skew, if therefore by heat-resistant part covering joints part and leading to
Cross limiting mechanism to be limited, then can reliably prevent the position of electroforming brick from offseting.
Preferably, in such a configuration, heat-resistant component is burned brick.
That is, the general low thermal conductivity than electroforming brick of thermal conductivity of burned brick.Therefore, by being made up of heat-resisting structure burned brick
Part, the heat-resistant component low thus, it is possible to inexpensively obtain thermal conductivity ratio electroforming brick.
In such a configuration, it is also possible to which the space between supply pipe and electroforming brick is filled with glass.
Here, glass can be melten glass, or glass dust.That is, even if in the case where being glass dust, also can
Heat during due to glass manufacture and melt, so as to the space filling melten glass between supply pipe and electroforming brick.Therefore, if
To the space filling glass between supply pipe and electroforming brick, then in glass manufacture, the outer surface of supply pipe is tight with melten glass
Paste, and the inner surface of electroforming brick is close to melten glass.The thermal conductivity of melten glass is of a relatively high, therefore in supply pipe
The heat of the melten glass of portion's flowing is easily transmitted to supply pipe, melten glass, electroforming brick successively, to the sky in the outside of electroforming brick
Between heat release.
In such a configuration, it is also possible to which the space between supply pipe and electroforming brick is provided with other electroforming bricks, and
And in the gap being arranged between the electroforming brick in space and supply pipe, glass is provided with the way of the outer surface for covering supply pipe
Layer.
So, supply pipe is close to electroforming brick via glassy layer.The thermal conductivity of glassy layer is of a relatively high, therefore is supplying
To the internal flow of pipe melten glass heat easily successively to supply pipe, glassy layer, electroforming brick (the electroforming brick of combination and
It is provided at its inner portion the electroforming brick in space) transmission, to the space heat release in the outside of electroforming brick.
The glass-making processes involved in the present invention completed to solve above-mentioned problem are characterised by, using appropriate
Possess the glass manufacturing apparatus of said structure to manufacture glass.

The electroforming brick 11 of square tube shape.
In detail, limiting mechanism 14 possesses the burned brick as heat-resistant component contacted with the outer surface of electroforming brick 11
15 and the fixed mechanism 16 of fixed burned brick 15.
The thermal conductivity ratio electroforming brick 11 of burned brick 15 is low.In detail, the electroforming brick at 1200~1350 DEG C of temperature in use
11 thermal conductivity is, for example, 4~6W/ (mK), and the thermal conductivity of the burned brick 15 at 1200~1350 DEG C of temperature in use is, for example, 1
~2W/ (mK).As burned brick 15, for example, can use alumina series, zircon system, aluminum oxide-zircon system, silica
System, mullite system, the burned brick of clayey system.As electroforming brick 11, for example can using alumina series, AZS systems (aluminum oxide-
Zircon-silica-based) electroforming brick.It should be noted that as heat-resistant component, in addition to burned brick, it is possible to use resistance to
Thermometal (for example, INCONEL (registration mark) of Special Metals company systems, SUS310S (JIS specifications)), heat-resisting glass
Glass (for example, quartz glass), heat stable resin etc..
Here, as heat-resistant component, thermal conductivity ratio electroforming brick 11 heating resisting metal high is used in substitution burned brick 15
In the case of, preferably encasing 13 is also made up of heating resisting metal.
Fixed mechanism 16 possesses the abutting plate 16a that is abutted with burned brick 15 and will abut plate 16a to the side of burned brick 15

Brigadier abuts the mechanism that plate 16a is pressed to the side of burned brick 15, is not particularly limited.For example, as pressing mechanism 16b, can
To use working cylinder, linkage etc..
As shown in Figure 3, burned brick 15 is more long on the direction orthogonal with the length direction of supply pipe 8.Along supply
In the case that the length direction of pipe 8 is observed, the exposed area not contacted with burned brick 15 in an outer surface for electroforming brick 11
Non- exposed area of the total length A than being contacted with burned brick 15 total length B+C it is big.Thus, in an outer surface for electroforming brick 11
The area of exposed area is bigger than the area of non-exposed area.For example, it is preferable to the area of exposed area is the area of non-exposed area
5~10 times.It should be noted that burned brick 15 can also in the way of the length direction along supply pipe 8 is formed as strip with
The outer surface contact of electroforming brick 11.

Multiple opening portion 13a.Thus, prevent from hindering the melten glass G in the internal flow of supply pipe 8 to put due to encasing 13
Heat.It should be noted that forming air-flow by the space between encasing 13 and electroforming brick 11, it is also possible to obtain same effect
Really.In the case where air-flow is formed like this, opening portion 13a can be set in encasing 13, it is also possible to be not provided with opening portion
13a。
This structure according to more than, limiting mechanism 14 is via the burned brick 15 as heat-resistant component and the appearance of electroforming brick 11
Face contacts, therefore, it is possible to prevent from making connecing for the limiting mechanism 14 contacted with the outer surface of electroforming brick 11 because of the heat of electroforming brick 11
There is the situation of thermal deformation in contact portion.Therefore, by limiting mechanism 14, the restriction state stabilization of electroforming brick 11 can be made, is contributed to
The stabilisation of glass manufacture.
In addition, the thermal conductivity ratio electroforming brick 11 of burned brick 15 is low, therefore the heat of electroforming brick 11 not easily passs through burned brick 15
Transmitted to fixed mechanism 16, encasing 13.Therefore, fixed mechanism 16, encasing 13 can use the low cheap gold of heat resistance
Category part.
Additionally, the area ratio of the exposed area not contacted with burned brick 15 in an outer surface for electroforming brick 11 with fire
The area of the non-exposed area of the contact of brick 15 is big, therefore is difficult to hinder supplying because of the low burned brick 15 of thermal conductivity ratio electroforming brick 11
To the heat release of the melten glass G of the internal flow of pipe 8.Therefore, even if increasing the flow of melten glass G, supply pipe 8 is led to
Electrical heating etc., it is also possible to be easily desired viscosity by melten glass G management.Will even if present inventor etc. confirms
The flow of melten glass G is set to degree as about 1000kg/h~1200kg/h, it is also possible to by melten glass G management to be wished
The viscosity of prestige.
