2 The main technical performance:
The tempering glass heat soak furnaces is made as the Europe standard which is strengthen safety of glasses. Adopting solid state relay. The computer can record and control the parameters intelligently. Temperature control mode is auto completed by electronic control system, which based on PLC and Kingview. The temperature and the result can be record and print automatically each time. The air circulating system is made up by12 blowers. There are six convection fans on the top , at the same time add Control of cooling by 2 cooling fans. There are 20 thermocouples in the heat furnace body, can monitor temperature on surface of glasses from every area. 6 thermocouples distributed on the top of the furnace can monitor the air temperature in the furnace3 Process parameters:
According to EN14179-1:2005 standards, it can achieve the following temperature and wind cycling by computer logic control
Normal heating temperature(Below 50ºC) to limit requirements temperature (290 ºC ±10 degrees) 60 min-120 min;
Keep the top limit temperature (290 ±10 degrees) 120 min-480 min;;
Temperature to cooling temperature (70 degrees) 120 min--480 min; The maximum temperature is able to adjust
±10ºC Empty furnace :the biggest difference temperature: ±10 degrees;
±10ºC Full furnace temperature: the biggest temperature difference is :±10 degrees;
Constant temperature: normal temperature to 320 degree, can be set in a random;
Constant temperature and time limit alarm temperature can be set in a random;
Attachment One
Heat soak time/temperature rules
To implementation of the equipment acceptance work to achieve EN14179.The following requirements for process and control, as below:
1, calibration standard:
Homogeneous system must follow the picture 1. The system must be able to achieve the load of 100% and 10%.
Picture 1 Standard Homogeneous time/Temperature rules
T Any pints of glass temperature.
t Time hour
t1 Time of first piece of glass to 280 ºC
t2 Time of last piece of glass to 280 ºC
1 The first piece of glass temperature to 280 ºC
2 The last piece of glass temperature to 280 ºC
3 Glass temperature
a Heating period
b Constant temperature period
c Cooling period
d Ambient temperature
Note 1: full load depends on the size , the thickness of the glass and furnace volume. General base on 6 mm or 8 mm thickness, the distance between the glass depends on the location, type of glass and interal things shape decision.
Note 2: The minimum distance is 20 mm.
2. the collection of temperature
Inner furnace is no less than 6 points fixed temperature gathering and glass surface is more than 20 point temperature gathering, this some points is under the standards of the EN14179-1:2005 of installation, put, calibration .
Note 1: the furnace and glass surface temperature can be tested in full load .
Note 2: the furnace temperature can control unit monitoring at the air outlet. Glass surface temperature is measured of the hot good contact thermocouple in the glass surface.
3,Test procedure, content
a, At the beginning, the air temperature of inside the furnace should be more than 50 ºC.
b. During the heating, should be heated to the last piece of glass temperature to 280 ºC.
c. During the heating, any glass surface temperature should not exceed 320 ºC.
d. During heating, the following parameters must record automatically:
a. Tc any time the temperature of the monitors
b. t1 Time of first piece of glass to 280 ºC
c. Tc1 monitors time
d. t2 Time of last piece of glass to 280 ºC
e. Tcmax The highest temperature of monitors
f. tcmax The time of the highest temperature
g. Tglass Any time glass surface temperature
U keep period from in the time t2 to two hours. Glass surface temperature is in the range of 290 ºC ±10 ºC. Tc Monitor temperature need to record down.
U cooling section begin in t2 + 2 h Monitor temperature Tc need to record. When Tc to 70 ºC furnace can open .
U Each phase of the time requirements (100% load) : warming period :120min≤a≤480min,can be adjusted continuously; Constant temperature period:60min≤b≤480min , can be adjusted continuously; Cooling period: 60min≤c≤240min, can be adjusted continuously.
