The Latest High-Precision Forced Convection Tempered Glass Manufacturing Machine

Product Description

GLASS TEMPERING FURNACE

Product Description

Machine structure and working principle
This machine is consisted of Loading section, Heating section, Flat Tempering section, Unloading section, Blower System and Control System. The glass sheet enters into heating oven from loading table, and tempered & cooled in flat quench & cooling section after heating. It goes to unloading table to finish process.
3.1 Loading section
Loading section is consisted of compound steel structure frame, transmission system, photo-electric switch and universal ball elevating table etc..
Drive motor of loading section is drove by inverter, transporting the fixed glass sheet to the photoelectric sensor of front door of the heating section and ready for enter the furnace.
When glass is entering the furnace, rollers in loading section are ran in high speed through motor driven by inverter, transporting the fixed glass to the heating furnace for heating. Encoder will exactly measure and record the total length of the glass. Moving distance of loaded glass sheets can be changeable through man-computer interface according to glass size.
Universal ball frame with pneumatic actuator will be manual controlled elevating, which is suitable for bigger size glass sheets loading.
3.2 Heating section
The heating section includes the roof lifting mechanism, heating system, fast cooling system, thermal balance system, ceramic rollers, the length measuring and temperature measuring devices.
The heating furnace is divided into upper and lower parts. The upper part can freely move up and down by the roof lifting mechanism for easy maintenance. Latest heat-insulation material is chosen for heating oven body, the connection of which is also specially handled for further better heat preservation.
The fast cooling system is for fast cooling when the heating oven is needed to reduce temperature.
The heating structure is lattice type. Upper and lower parts of the furnace are heated independently in each heating zone. Upper heating area and lower heating area will be divided into several small areas according to furnace size. Each heating zone has its thermocouple forming independent control loop. The heater is good quality alloy material to service more years.
