High borosilicate glass tempering furnace: What are the preparations for tempering furnace operation?

A tempering furnace is equipment for tempering glass and producing tempered glass. Operating a tempering furnace requires rigorous training. So, high borosilicate glass tempering furnace: What are the preparations for tempering furnace operation?

High borosilicate glass tempering furnace: What are the preparations for tempering furnace operation?

1. Before starting work, wear personal protective equipment and check if the air compressor, fan, reheating furnace transmission, gas path system, and lubrication system are functioning normally.

2. Check if other related processes (edge grinding, drilling) are qualified, and the preparation for glass sheet arrangement and collection.

3. Understand the production content of the shift and prepare the necessary shelves, packaging paper labels, cork pads, etc.

4. Check the preparation of the tempered glass. If there are quality problems such as cracks in unground glass, glass that may cause furnace explosions is not allowed to enter the furnace.

What does the heating section of the tempering furnace consist of?

1. The heating section mainly consists of the heating furnace body, transmission system, and lifting system.

2. The heating furnace body frame is welded using high-quality steel and steel plates according to national standards. It has high strength, good rigidity, and a compact and sturdy structure. The furnace body is divided into upper and lower parts. The upper part of the furnace body can be remotely raised and lowered, which facilitates the installation, replacement, maintenance, and cleaning of the roller track. The furnace lining uses high-quality silicon aluminum refractory fiber compression plates, which have the characteristics of low thermal conductivity, good insulation effect, low density, and small heat storage loss. Using unique pre-tightening anchoring technology significantly reduces furnace body heat dissipation and thermal short circuits, effectively lowering the furnace body surface temperature, and improving thermal efficiency.

3. The furnace's ceramic roller track uses world-renowned products. The transmission mechanism uses a circular transmission belt and a linkage synchronous transmission belt, which greatly improves transmission accuracy, reduces the impact of transmission system vibration on the ceramic roller track, eliminates deviation, and minimizes scratches caused by asynchronous transmission. The furnace has high-performance patented heaters, more heating zones, and a more uniform furnace temperature; the surface energy of the heating element is low, it has good thermal shock resistance, and a long service life.

4. When the glass enters the furnace, the furnace door opens, and the internal fragment feeding roller and ceramic roller are synchronously driven to send the glass into the furnace; after that, the furnace door is closed. The glass is driven by the roller track inside the furnace body and swings back and forth within the set effective range. The glass is heated evenly, and the heating quality is better; at the same time, it ensures that the ceramic roller track does not deform or bend, and the overall life of the furnace is long.

What does the flat tempering section of the tempering furnace consist of?

1. The flat tempering section consists of a cooling air grate, a conveying roller track, and an air collecting box.

2. The nozzles of the air grate are made of alloy. The cooling air grate is divided into upper and lower parts, respectively connected to the air distribution center. Intelligent control, according to the different thickness of the glass, automatically adjusts the distance between the air grate and the glass, so that the spraying distance is always at the peak value. Therefore, the cooling effect is good. The upper and lower air grates are connected in parallel by several air distribution grates. Cold air is sprayed from the spray holes of the air grate, sprayed at high speed onto the glass, and then quickly and steadily diffused. By changing the frequency of the fan motor through a frequency converter, the air flow rate and pressure can be adjusted to the values required for tempering different glasses. At the same time, the glass is still swinging back and forth on the roller track, greatly improving cooling efficiency and significantly improving the problem of glass wind spots.
