LIJIANG Glass LJ6030-A Automatic Tempering Glass Equipment heats the flat glass and then quenches it, so that the surface layer of the cooled glass forms compressive stress and the inside of the glass form tensile stress, to improve the strength of the glass and make ordinary annealed glass into tempered glass.
Description of the Equipment
1. Brief introduction
This tempering line includes a loading table, heating section with forced convection, passing section, quenching and cooling section, unloading table, and control system. It is used to produce flat tempered glass for furniture, home appliances, structural, architectural glass and Low-E glass, etc…
2. Loading Table
The loading table is made of rubber-covered Kevlar-rope rollers. When the glass is put onto the rollers, the glass will be conveyed automatically to the entrance of the furnace where it will be in the ready-to-enter position, and the rollers will then stop moving. It will send the glass into the furnace once the computer control system gives enter command.
1.3 Heating Section
The structure of the heating section is of a double-layer box type covered with the insulating glass material. Inside this section, there is a conveyor system with high temperature-resistant ceramic rollers, which are imported from well-known manufacturers. Heating elements are installed on the upper layer and lower layer of this section. The upper layer radiation plate is a special heat resistant and anti-corrosion cast material. The heating element is of an integrated part with spiral-type resistance erected on the ceramic part, and it is easy to replace. When the glass is going to enter the furnace, the front door of the heating section opens, and the rollers of the loading table and heating section move at the same time. When the glass is in the furnace, the front door will close and the glass on the rollers will oscillate back and forth at a distance calculated automatically by the control system, such that the glass will be heated evenly. The heating elements are in a matrix layout.
1.4 Convection heating system
Our unique convection system consists of a compressed air system.
The air is compressed into a spiral shape tube inside the heating chambers (top and bottom), where air temperature reaches the temperature of the furnace before being blown into the glass. A perfect convection system, with the lowest power consumption and maintenance, cost when we compare it to other competitors.
1.5 Passing Section
The Passing technique is used to produce 4-6 mm. When used, the passing section can save power and reduce energy consumption. It’s no need to open the bigger blower after the passing section. It can almost save 60% of the energy of the quenching.
1.6 Flat Quenching Section
The alloy sections and steel sheets that we are using are tempered metals to avoid any possible deformation due to heat welding. And this ensures effective air flat distribution. Rational nozzle aperture and arrangement of air hole guarantee the glass even cooling. The upper and lower quenches are linked and combined with individual drives, which can actually control the accurate height for the air nozzle of quenches.
Matched with balance control of upper and lower air amount, the top and bottom of the glass can get the best air pressure on both sides, so as to ensure the flatness of tempered glass.
The 1.7 Unloading Table
The unloading table is similar to the loading table. When the glass is transported to the end of the conveyor, the rollers will stop, and the glass can be taken away by hand, or by a robot if it is available at the customer’s factory.
1.8 Control System
The control system includes the followings:
Process parameters storage and recall, such as glass thickness, size, color, glass type, and may be different sources of float glass and etc. Whenever you temper a new order for different thickness, size, color, type, source and etc., you just enter the process parameters, and the system will save these process data. Next time, when you have the same order, you can re-call the data, and the machine will automatically use the stored processing data to produce.

Specifications for the correct use of tempering furnaces
1. Before heating the heating furnace, the electric furnace wire, main drive, and related components must be checked, and the heating can be performed only after the confirmation. There must be someone watching over the heating process.
2. The process parameters of the tempering unit must be adjusted by the operator according to the process requirements, and it is strictly forbidden for others to adjust them randomly.
3. The size of the glass that needs to be processed in the furnace should be in line with the processing capacity of the tempering unit, and it is strictly forbidden to be too large or too small to avoid damage to the equipment.
4. When adjusting the radian in the production of bending and tempering, people must direct and operate the computer to avoid misoperation and cause personal injury.
5. When lifting the upper wind grille, you must be extra careful to prevent the chain from breaking and damage to people. After the upper wind grille is raised, if you need to enter the wind grille for operation, you must insert the iron pin into the safety hole before entering to ensure safety.
6. When it is necessary to adjust the chain, sprocket, and other similar parts or remove the sundries on the surface, it must be stopped before work. It is strictly forbidden to operate by hand when the above parts are rotated to avoid accidents.
7. After the transmission stops due to sudden power failure, computer crash, etc., the glass in the furnace must be shaken out of the furnace by the hand crank mechanism quickly, and the ceramic roller table should keep rotating when the furnace temperature is above 300 degrees, to avoid causing Roller deformation.
8. During the operation of the equipment, it is necessary to frequently check the operation of the power distribution cabinet, the main drive, the forming section, the upper and lower sections, etc., to discover hidden dangers in time.
Daily maintenance and maintenance of tempering furnace
1. Clean the surface of the equipment (including the console and the electric control cabinet), especially the photoelectric sensors and the glass of the instrument should be clean and dust-free.
2. Bearing lubrication, tempering furnace main drive bearing, ceramic roller bearing, furnace door bearing, furnace roof lift drive shaft bearing, and furnace roof lift trapezoidal spiral bearing, need regular inspection and refueling. The lubricant used is lithium-based grease. Generally speaking, the lubrication cycle is half a year for ceramic roller bearings, and the other is annual.
3. The daily inspection of each component, and check the work of each moving component (such as air grille, furnace door, valve, etc.) should be flexible and free from sticking.
4. Replacement of parts. Thermocouples, heating elements and other parts should be replaced in time if there is a problem.
