Specific embodiment
Upper segment 1 is equipped on front side of annealing furnace, rear portion is equipped with lower segment 4, and heating is equipped between upper segment and lower segment
Section 2 and tempering section 3；
Live-roller 6 is housed on tempering furnace body, the driving wheel of live-roller is passed by belt with the wheel of driving motor 5 that lower part is arranged in
Dynamic connection, the power as glass run；
Be equipped in the heater box of bringing-up section between the upper and lower every heater 7, heater is to wind heating wire on ceramic tube 7.1
7.2 matrix composition, is respectively arranged with temperature sensor 0 in each ceramic tube, ceramic tube is forward arranged, and passes through heating module control
Glass heating temperature processed is at 650~1000 DEG C；
It is provided in tempering section between the upper and lower every two layers of air grid 8, air grid is made of the air grid pipe 8.1 for being separated by arrangement, each air grid pipe
One side be equipped with several blowholes 8.2, each air grid Guan Junyu plenum chamber 11 is connected to, and one to multiple is equipped on plenum chamber
Blower 10, the blower are frequency control, and air grid pipe is laterally arranged, is provided with wind pressure sensor 01 in plenum chamber, passes through blowing
Module controls blow pressure in 12000~20000 pas；
Power module 9.1, power module and 9.2 circuit connection of transmission module, and and heating module are equipped in PLC controller 9
9.3 and 9.4 circuit connection of blow-off module.
The power module is external power supply and derailing switch, and the transmission module is the derailing switch of driving motor, transmission speed
Degree can prior program setting, heating module is heater power transmission and power-off switch device, and according to the data of temperature sensor into

Block includes blower motor frequency converter and wind pressure sensor.
PLC uses multiple spot relay control type, and has the input of control program, storage and control function.
The course of work:
Glass to be toughened is placed in upper segment, is transmitted by live-roller to the intracorporal bringing-up section of furnace, is heated in bringing-up section,
Glass swing while heating reaches setting by temperature sensor sensor heater temperature and adds so that glass is evenly heated
After hot temperature, the glass after heating is transported to by tempering section by live-roller, tempering section glass also carries out swing, using blowing
Wind module controls blow pressure, and the glass after tempering is transported to bottom sheet after reaching tempering blow-time, then through live-roller
Duan Shang is removed from lower segment, and the transmission of glass is realized with the transmission module swung by PLC controller.
The technical principle of flame resistant glass tempering:
Glass tempering is to form compressive stress layer, internal formation tensile stress layer in glass surface；When glass is by external force, pressure
Stressor layers can offset part tensile stress, avoid glass breaking, to achieve the purpose that improve strength of glass.Moreover, glass
The micro-crack on glass surface becomes subtleer under this compression, also improves the intensity of glass to a certain extent, and
With a degree of fire line.But when heating temperature is lower, when blowing tempering pressure is lower, complete tempering cannot be reached
Effect, so fire resistance period is short, refractory temperature is low, and inside glass is there is also tensile stress, when proposing glass heating temperature
Gao Shi can thoroughly eliminate tensile stress in glass, under conditions of higher temperature, immediately in the case where guaranteeing infusible situation
Rapid cooling is blowed with higher wind pressure, glass tensile stress can be made to improve, achieved the effect that complete tempering, so with
When flame resistant glass, can fire resistance period it is long, refractory temperature is high, and will not rupture.
Advantage:
Traditional tempered glass heating temperature is at 650 DEG C, and blow pressure is in 1000~12000 pas, so the glass fire line of tempering
It can be poor.And this furnace glass heating temperature, at 650~1000 DEG C, blow pressure is in 12000~20000 pas, therefore the glass after tempering
Glass fire resistance period is long, and does not rupture, and safety is big.
Feature:
Be experimentally confirmed, ordinary glass fire resistance period at 15 minutes or so, the glass of present apparatus tempering can fire resisting exist
It 30 minutes or more, will not be chipping glass melting trickling.
