PINHE Energy Efficient Single Chamber Horizontal Forced Convecion Tempered Glass Furnance Machine Line

1-1.Loading Section of the Horizontal Forced Convecion Tempered Glass Furnance Machine Line：

The loading section is composed of driving rubber rollers, loading drive motor, encoder, dual photoelectric sensor, universal wheel lifting platform, lighting device and tools table. The driving motor of loading section is driven by frequency converter, and the rubber roller is driven by the chain to transfer the placed glass to the photoelectric sensor of front furnace door, so as in ready-to-enter-furnace position.

During loading process of Horizontal Forced Convecion Tempered Glass Furnance Machine Line, the motor drives the rubber roller to move at low speed, and the encoder accurately records the glass total length in the furnace. During glass entering, the inverter drives the loading motor to make the loading section rollers and heating section ceramic rollers to move synchronously at high speed, then the glass will be transmitted into the furnace for heating. 

1-2.Heating Section of the Horizontal Forced Convecion Tempered Glass Furnance Machine Line：

This is one of the most important part of Tempered Glass Furnance Machine Line. The heating method is upper and lower zones heating. The upper and lower heating zones are divided into several small areas according to the furnace body size, and each area is equipped with a thermocouple to form an independent control loop. The Tempered Glass Furnance Machine Line heating element is made of high quality alloy material for longer life. The forced convection system composed of 4 sets convection blowers (with split design for high efficiency and energy saving, also easy maintenance), inlet and outlet pipes.

Above system makes the heating mode of glass upper surface in heating section is changed from only radiation type to radiation and convection together, while convection is the main type. In this way, the heat absorption rate of glass surface is improved, which makes the glass upper and lower surfaces are quickly heated to balance.

TheTempered Glass Furnance Machine Line heat balance system can be adjusted automatically according to glass thickness and types to ensure the furnace temperature uniformity and the tempered glass flatness. It is especially suitable for tempering low-E glass and coated glass with different heat absorption rates on both sides. 

Ceramic roller of the Tempered Glass Furnance Machine Line adopts high quality brands. The belt driving and frequency control are adopted in the Tempered Glass Furnance Machine Line to ensure the synchronization and stability of ceramic roller movement. During entering furnace, loading section rollers move synchronously with heating section rollers to enter the glass into furnace. 

In the heating process, the main drive motor drives the ceramic rollers to do reciprocating movement, so that the glass will be heated evenly. When the glass is out of furnace, the quenching section rollers move synchronously with the heating section rollers to transmit the glass into quenching section for tempering. The Tempered Glass Furnance Machine Line furnance rear door is equipped with automatic opening function when power and gas is off, so as to prevent heavy losses caused by glass being left longer time in the furnace in accidents.

1-3.Flat Tempering Passing Section of the Horizontal Forced Convecion Tempered Glass Furnance Machine Line：

The passing section is composed of transmission roller, upper and lower quenches, quench lifting mechanism and air inlet. 

The quench is trapezoidal combined shape, and the air nozzle is made of aluminum alloy. The transfer roller is a kind of steel roller twined with imported kevler belt. 

When the glass is about to come out of the of the Tempered Glass Furnance Machine Line furnace, the upper and lower quenches are close to form a gap. The rollers move synchronously with the heating furnace ceramic rollers to transmit the heated glass into quenching section for tempering.

1-4.Flat Tempering Cooling Section of the Horizontal Forced Convecion Tempered Glass Furnance Machine Line：

The cooling section is composed of transmission rollers, upper and lower quenches, quench open & close mechanism, air inlet, etc. 

The quench is trapezoidal combined shape, and air nozzle is made of aluminum alloy. The transfer roller is a kind of steel roller twined with imported kevler belt. In cooling process of of the Tempered Glass Furnance Machine Line, the glass will be moved back and forth on the rollers, so as to ensure smooth blowing. 

1-5.Unloading Section of the Horizontal Forced Convecion Tempered Glass Furnance Machine Line：

Unloading section structure is basically same as that of loading section of Tempered Glass Furnance Machine Line. When cooling glass is completed, it is automatically transmitted to unloading section, and glass will be stopped automatically on reaching unloading section end. The tempered glass is manually removed from unloading section. Then the process is finishedby the Tempered Glass Furnance Machine Line.
