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 50℃) to limit requirements temperature (290℃±10℃) 60 min-120 min;

●Keep the top limit temperature (290℃±10℃) 120 min-480 min;;

●Temperature to cooling temperature (70℃)120min--480min;Themaximum temperature is able to adjust

●±10℃ Empty furnace :the biggest difference temperature: ±10℃

●±10℃ Full furnace temperature: the biggest temperature difference is :±10℃；

●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；

Heat soak time/temperature rules

To implementation of the equipment acceptance work to achieve EN14179-1:2005.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℃

t2 Time of last piece of glass to 280℃

1 The first piece of glass temperature to 280℃

2 The last piece of glass temperature to 280℃

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.
