Section) melted material 121, there is the temperature and at least one of viscosity that suitably form glass (e.g., glass tape 103) to provide
Melten glass.In some embodiments, when melted material 121 flows through the melten glass housing region 165 of container 160
When, melted material 121 can cool down.For example, in some embodiments, flowing to the melting glass in melten glass housing region 165
The first temperature " T1 " of glass can be higher than the second temperature " T2 " of the melten glass flowed out from melten glass housing region 165.Therefore,
First temperature " T1 ", which is higher than second temperature " T2 ", can indicate when melted material 121 flows in melten glass housing region 165
Between time when time and melted material 121 are flowed out from melten glass housing region 165, heat is moved from melted material 121
It removes.Equally, the first temperature " T1 " is higher than second temperature " T2 " and can indicate to flow to melten glass housing region in melted material 121
Position in 165 and in melted material 121 between the position that melten glass housing region 165 is flowed out, heat is from melting material
Material 121 removes.
Any one or more of conduction heat transfer, convective heat transfer and radiant heat transmitting can be defined when heat is from melting
When material 121 is transmitted to container 160 (e.g., chamber wall inner surface 162), by chamber wall 161 (e.g., from chamber wall inner surface 162
To chamber wall outer surface 163) when, from container 160 (e.g., chamber wall outer surface 163) arrive 200 (e.g., housing wall inner surface of shell
203) when, by housing wall 201 (e.g., from housing wall inner surface 203 to housing wall outer surface 204), Shi Jicong shell 200 is (e.g.,
Housing wall outer surface 204) to environment 250 when, the cooling of melted material 121.In some embodiments, environment 250 may include
Shell 200 can be positioned on room therein and at least one positioning in the room and surround any one or more of shell 200
Object.
Therefore, can transmit and (e.g., remove) from melted material 121 can be at least partly with the heat for cooling down melted material 121
Based on can by heat from melted material 121, pass through chamber wall 161, pass through housing wall 201 and transmit reach environment 250 rate.
The output of method 100 of glass and defeated is handled with glass processing apparatus 101 in some embodiments it may be desirable to increase
Out, for example to increase the rate for producing glass tape 103.In some embodiments, glass is handled with glass processing apparatus 101
The increased output of method 100 and output can correspond to the increased stream of the melted material 121 by glass processing apparatus 101
Speed.When operating glass processing apparatus 101 in the increased situation of the flow velocity in melted material 121, it is possible to provide from melted material 121
The rate transmitted to the heat of environment 250 is increase accordingly, to maintain and increase the cold of (at least one therein) melted material 121
But rate (e.g., to provide melted material 121, have and suitably form the temperature of glass and at least one of viscosity).Therefore,
Disclosed method and equipment can provide the unobtainable melting of method from existing glass processing apparatus and processing glass
The cooling rate of material 121.In addition, disclosed method and equipment can increase the melted material 121 in glass processing apparatus 101
Cooling rate, without to processing glass method 100 significantly changed, and will not to glass processing apparatus 101 into
Row is apparent to be changed.
