Features of each section:
  1. Loading tables, heating chamber,flat quenching section and unloading table are installed with independent drive systems, and their own running speed can be automatically controlled by computer. Every mode also can be changed automatically.
  2. Heating chamber: On/ off switch is electric control. Up/down quenching section and air pressure balance adjustment : electric control. Overall air pressure adjustment: Computer system control. Blower: converter start-up and control.
  3. Function Feature: If sudden power off, emergency glass expelled can be manually operated on the main driving. If under voltage or malfunction, there is automatic alarm.
4.1 Loading table
The loading table is composed by transmission rollers, driving system and iron frame.
The rollers are made of rubber, with stable transmission and preventing scratching during transportation. Transmission is controlled by converter motor. Inching,stepping or running with ceramic rollers can be optional. Glass length detection device is designed in the table, which can be achieved overall process under monitored. Besides, there is a set of pneumatic lifting device for big size glass. It is convenience to load this big glass from sideways.
4.2 Heating chamber
The structure of heating chamber:
The shell of heating chamber is composed by section steel and steel plate, both ending are installed with heat-resistant stainless steel chamber door and on/off by pneumatic. For the convenient maintenance, the heating chamber is vertical type up/down structure, with 1 set electric up/down device. The interior chamber is made of aluminum silicate plate and thickness is 230mm. Heating elements: SHOUGANG 0Cr21A6Nb. Space indicated points set in the chamber which exposes each area working status.
Driving and transmission:
The heating chamber transmission adopts double round belt, orthogonal setting, which can ensure the stable running. High quality ceramic rollers are installed inside, which has good resistance on fast temperature changing. The glass will run reciprocate on the ceramic rollers inside the heating chamber, its travel range and reciprocate period can be automatically adjusted by length testing detection device of the control system, which ensure the heat inside chamber is absorbed by glass evenly.
Heating elements and temperature control:
Heating elements and temperature testing elements are installed inside the chamber. They are separated to many regions, each region controlled by computer independent. The heat-resistant alloyed heating elements are fixed by heat-resistant support which can increase its service life and easy to replace.
Blower convection system:
The convection system is composed by: 6 sets of convection blowers on top. There are many spray booth on the air pipes. Air is transmitted through by the blower convection, and then spray on the glass surface from air pipe. The flow and time of this high temperature air could be controlled, to satisfy different heating parameters. According to the real requirement, the air pressure is also controlled sectionally (The convection motors are controlled by frequency converter).
4.3 Flat quenching section:
4.3.1 Loading glass with set dimension size and it will through into heating chamber. After the glass absorb enough heat for tempering, it will come out from chamber quickly and transferred to quenching section with oscillating traverse for cooling. Air pressure need to be adjusted as requirement for producing different thickness. Glass will be transferred to unloading table and unload after cooling.
4.3.2 Pass Section
Pass section is design for 4mm glass, use 2 blower for cooling glass. When 4mm glass come out from heating chamber, big blower will open to quenching glass in pass section, after few second, big blower switch off and small blower on, glass transfer to cooling section for cooling. Advantage of pass section is 4mm glass can be full loading area, so production will be 50% higher than only use one bigger blower but half loading area. What is more, this design can be lower installation power and 60% energy saving for quenching. Quenching and cooling section lift system independently can automatically adjust the distance between upper side and down side as best effect for glass.
4.4 Unloading table
Unload table is similar with loading table and its rollers with twining aramid fiber and rubber rollers. Beside, for heavy glass. Consult heavy glass convenience, iron frame can rise and fall by pneumatic device, so operator can load glass by side easily.
4.5 Blower system
The blower mouth is connected by soft pipe with air collecting box (plenum box), which can vibration isolation. In air box, air pressure and flow being well distributed. Air will be transfer to up and down air grid, come out form nozzle to temper and cooling glass.
4.6 Electric control system
  1. This system is composed by HMI control cabinet, PLC, Frequency converter, Solid state relay control cabinet and Blower control cabinet.
  2. All technological parameters such as chamber temperature, air pressure and blowing rate can be set, saved and applied as an order by computer.
  3. Every action of the production flow is achieved by PLC, Monitor Device and Executive Device.
  4. There is stepping function on loading table, so moving distance can be set by length of glass.
  5. When glass transferred into chamber, the system will be detect the length to decide the oscillating distance inside the chamber and quenching section.
  6. Every main transmission status will dynamic shown on screen.
  7. The air pressure of blower system is adjusted by frequency converter, manual also optional on the equipment.
  8. The heating chamber can be open/close on the vertical direction. Quench up/down can be adjusted to different position as require.
  9. The equipment is set will automatic/manual emergency device when power failure, the glass can be transferred outside automatic/manual and prevent ceramic rollers from damage automatically.
4.7 Alarm system
Monitor the equipment running status. If there is something wrong, the furnace will alarm automatically. Besides, we could also monitor all the motors working status. If the motors damaged or power off, it will alarm (Including up/down motor of heating chamber,up/down motor of quenching section, blower cooling fan etc). Also for monitoring computer working status. For example: it will alarm if the computer shut down. Same as the heating fuses: if the fuses are abnormal, automatic alarm will remind and cut off the power.
Flat Glass Tempering Furnace with Blower Motor Convection&Pass Section
Application: On-line, off-line single silver and double silver Low-E glass, high grade instrumenta-tion, electrical appliances, interiors decoration, solar glass, furniture, decorative, architecture,building laminated glass,etc.

Glass tempering furnaces are designed to make finished pieces of glass both stronger and safer in the event that they break. Glass tempering furnaces heat up a piece of glass to a very high temperature, usually over 600° Celsius, and then rapidly cool it uniformly using air jets, a process called quenching. The rapid cooling causing the surface of the glass to undergo extreme compression, making it much stronger against impacts and heat shock. Additionally, due to the intense pressures within the glass, if the glass fails, it shatters into several tiny and relatively spherical pieces, making it much less likely for people to become injured from the shards.

Characteristics

Matrix radiation heating combined with upper forced convection, equip with high temperature resistance convection fan and stainless air pipe, hot-air spray to the surface of glass verticality,speed up the heating for glass evenly. Internal recycle construction will not cause heat loss for energy-saving.lnner cleading structure of upper part heating chamber could effectively fix thermal insulation and reduce quantity of the dust inside chamber.Adopt the latest high pressure pass quenching section for 2.85-4mm glass tempering, which owns outstanding energy-saving feature.Furthermore, it can achieve the best performance for graininess, flatness and optical effects.Power-ful control system ensure automated production, friendly man-machine interface, convenient operation, and data security and reliability. Every step be controlled accurately by high precision, real time response and low interference system.
