Product Description

 OLIVASTRI FK RGC

Roller kiln type FK Rcg 18/1200 for bending

of thermal glass

 temperature of 950 ° C

Useful dimensions of the bending chamber 1200x1200x600

Maximum dimensions of the sheets to be bent 1100x1100x4 mm

Minimum dimensions of the plates to be bent

300x300x4 mm

Heating and bending cycle

15 minutes

= Production 1 pack every 7 min. 30 sec.

Cold-cold cycle about 70 min.

Annealing cycle 7.5 min.

Cooling cycle 47.5 min.

Total length of the oven 17 meters

2 meter kiln entrance roller conveyor, advancement operation

fast intermittent

Preheat 1.4 meters, fast forward operation

slow

Heating 1.4 meters, slow and fast forward operation

1.4 m curvature, fast forward operation

slow fast

1.4 mt annealing, fast slow forward operation

rapid

Cooling 11.20 meters, feed operation

slow

- A movable diaphragm divides annealing from cooling

- Rolls diameter 60, center distance 120 ceramic,

(for fused silica only i in the heating and bending area + 5%)

- Mixed heating: electricity, gas

- n. 4 burners of 20,000 Kg / cal. with automatic ignition and flame control

- n. 2 self-regulated gas zones

- 0.75 kW combustion fan

- 0.75 kW smoke suction fan

- 20 kW bending resistors

Lower drilling template consisting of shaped cordirite plates inserted between the rollers and

resting on a plate that will be raised by means of a pneumatic piston having

a maximum stroke of 500 mm

Upper template with wings that close in case of particularly closed curvature.

A lifter keeps 1 glasses lifted from the rollers

curved in the annealing zone over time

of curvature, after which the diaphragm is raised and while

the newly curved glasses come

transferred in annealing, those from annealing are transferred

1n cooling.

The movement of the rollers is controlled by 2 gearmotors controlled by inverters.

The 1st pulls the first six modules and has 2 tow speeds:

1 °) the normal slow forward speed

2nd) transfer speed to the next section in fast 8 - 10 times higher than the 1st

- 2 meters of kiln feeding roller conveyor with operating drive motor reducer

intermittent

- 4 m of kiln unloading roller conveyor pulled by the 2nd kiln towing gearmotor
