Glass Tempering Furnace

Horizontal Roller Hearth Flat Glass Tempering Furnace With Vortech Convection System

Loading and unloading tables  

The loading and unloading tables are similar in structure, and are composed of customized steel frame. 【 it is equipped with cylinder transmission mechanism lifting table, which can lift synchronously and stably, and is equipped with universal wheel.】The roller is composed of rubber roller and rope roller. High quality coating is used to ensure that the glass surface is not scratched. In terms of transmission control, the stepping time is adjustable, the conveying speed is adjustable, the furnace feeding interval is controllable, and the sensitive glass detection device is equipped.

Heating system

The structure of the heating section is of a double-layer box type covered with thermo-insulating 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, and the “Exposed Matrix Heating Design” is adopted. Compared with the traditional “radiant plate heating design”, this matrix system can improve thetemperature uniformity and heating efficiency in the furnace, and the heating elements are easy to replace. [The inside of the upper layer of the heating section is covered of 310S stainless steel with strong corrosion resistance.] The insulation layer is made of high-quality aluminum silicate plate. After scientific sorting and six side polishing, it has better heat storage capacity, can greatly improve the heat utilization efficiency. The heating section can open and close, and the upper heating section can be raised by the electric screw lifting device

Flat cooling section

The alloy sections and steel sheet that we are using are tempered metals to avoid any possible deformation due to heat welding. And this ensures effective air 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 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 in both sides, so as to ensure the flatness of tempered glass.

Electric control system

The control system includes the followings: Process parameters storage and recall, such as glass thickness, size, color, glass type and maybe 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.

Vortech convection system

Vortech convection system is our unique top convection system. The air is blown out from the Vortech Blower and heated by the heat circulation system and the waste heat in the furnace, and the hot air flow brings the heat directly to the glass surface. Combined with the “Exposed Matrix Heating Design” and refined diversion design, the production time of 6mm double silver Low-E glass can reach 280 ~ 300s / batch. A perfect convection system, with the lowest power consumption and maintenance cost when we compare it to other competitors. The convection system has mature design, stable structure, with convenient daily maintenance.
