Every, transversely arranged thermocouple, furnace wall is penetrated by forming furnace both sides, fixed insertion reaches measurement glass not in contact with glass plate
The purpose of plate temperature.
The device of above-mentioned measurement glass sheet temperatures specifically has the disadvantage that：
First, the temperature that fixed thermocouple mode is detected, is not glass plate actual temperature, because process operation requirement or bar
Part is limited, and there is certain space length thermocouple test side away from glass plate, and the temperature of detection is forming furnace local temperature, non-reality
Glass sheet temperatures.Georeferencing temperature when the temperature of fixed thermocouple detection only reflects that glass plate flows through forming furnace.
Furthermore, due to forming furnace process structure, the space temperature of body of heater central Glass plate both sides has differences.Than
Certain side such as furnace wall lowers the temperature because of glass plate and needs, and is connected with cooling water pipe, causes the temperature of the fixed thermocouple detection in furnace wall both sides
Angle value difference is present；Or, when shaping furnace interior cooling water pipe is changed so that forming furnace each point thermocouple is detected and passes through meter
Calculation machine calculate, display comprehensive furnace temperature achieved reliability it is not high because detected value non-glass plate actual temperature, for reference can
It is not high by property.
Therefore, glass plate actual temperature device in a kind of detection forming furnace how is designed, is the technology that we need to solve
Problem.
