Tempered Glass Testing Oven; Tempered Glass Testing Machine Furnace

Product Description

Heat Soak Furnace
This furnace is the accessory equipment for the production of tempered glass. After tempering process, the tempered glass could be put into the heat soak furnace for hot dipping process, this process could make the tempered glass which has the self- explosion fault breaks during this process to avoid any self-explosion during installation or using.

3. Electric control system
The control system adopts industrial control computer with user-friendly operation, displaying by monitor and opered by keyboard. The setting for temperature and temperature-keeping time could be set at will according to the process requirements. The temperature adjustment adopts PID control with 12 points tempering-control detector and 20 points soft-wire temperature-measuring detector for glass surface. There is multipath curve displaying and printing. The temperature curve history record could be checked. The electric elements adopts the imported famous brand.
4. The configuration for electric control system (according to CE standard)
4.1. Computer: Advantech
4.2. Monitor: 15″
4.3. Temperature collecting: Advantech Module with 8 channels
4.4. Communication system: Advantech communication module
4.5.Data line: SC-09 from Mitsubishi
4.6. Control software: Mingte
4.7. Temperature sensor: WZPK with 12 points
4.8. Glass temperature sensor: Heat-resistant thermal couple with 20 points

5. Electric control system principle
After start computer, set the temperature-rising time,temperature upper limit, Homogenizing time, temperature-reduction time, temperature-reduction over time, etc. press the heating-star button, the whole control process could be finished automatically according to the set curve. The temperature-collecting module would collect and create the real-time temperature curve and histrory temperature curve. The history temperature curve could be checked and inprited with inputing the random time.

6. Main function
6.1. Real-time temperature curve automatically creating function
6.2. History temperature curve automatically creating function
6.3. Temperature curve automatically checked and printed function (the printing is optional)
6.4. Recording system working situation automatically, such as starting up, quit system, etc.
6.5. Adopting PID control, the temperature curve could be set according to requirements.
