Detailed Product Description

Loading Section

The passing type flat glass tempering furnaces (toughening machine) uses plastic rollers; half-cross belt drives, is individual motor driven, able to step forward by single step operation and is also able to be synchronized with the heating section. The photocells are mounted on the loading section to be matched with the encoder on the body for measuring the length of glass and controlling the position and swing amplitude of the glass inside the furnace.

Heating Section

The heating section is insulated with qualified refractory aluminum silicate sheet, driven by hi-grade quartz ceramic rollers, matrix arrangement of heating elements, non-contact fuzzy control and automatic power compensation function, which satisfy the different requirements of heating power for different thickness of glass. The heating system for the upper and lower furnace is followed with control to enable the temperature inside the heating chamber to form a necessary gradient distribution, which can perform uniform heating for the glass surface and reduce glass distortion to a minimum. The unequal swing control is used for reducing wave distortion during the glass heating. Roller friction is effectively reduced and the quality of the glass surface is further improved with the stability of the half-cross belt drive, leading-in compressed air and sulphur dioxide and enhancing the thermal balance inside the furnace. 

 Quenching Section

  The alloy sections and steel sheet are cold riveted to avoid deformation by heat welding, effectively ensuring the entire flatness at the air face of the quench. Rational nozzle aperture and the arrangement of air holes guarantee the glass an even cooling. The upper and lower quenches are combined with linkage and individual drives, which can control the rational height for the air nozzle of the quenches. Matched with balanced control of the upper and lower air amount, the top and bottom of the glass can reach optimum heat radiation, so as to ensure the flatness of tempering glass.

 Unloading Section

  This uses aramid fiber roller and half-cross belt drives. The unloading can be done by single step operation. The glass can be directly unloaded from the unloading table. The loading and unloading tables are equipped with pneumatic elevation and side rollers for easy glass side unloading.

 Air Supply System

  This is composed of a high-efficiency high-pressure centrifugal fan, pipeline system and static pressure box. According to requirements, the pipeline system and static pressure box are mounted with gate valve, air adjusting and distribution units to ensure leading-in the cooling air with required pressure and in strict proportion to the upper and lower quenches. The hi-efficiency hi-pressure fan uses an integrated stand with shock dampers mounted on the floor, which effectively prevent vibration spread and are quick and easy for installation construction and maintenance.

 Electric Control System

  This system uses world famous brand-Japan Omro inverter, PLC, encoder and photocell and Shimaden solid-state relay, which allows stable and reliable running. The whole technological data can be stored with order type. This system has perfect safe system and alarm functions. The distance operation, trouble-diagnosis and troubleshooting can be carried out.
