Rules And Installation Precautions for Glass Tempering Furnace Loading

The main function of a glass tempering furnace is to use physical methods to temper glass raw materials. It utilizes the stress and tension generated by the rapid cooling of the glass surface after heating to enhance the strength of the glass. In the production process, in order to ensure that each tempered glass can meet the quality requirements, special attention needs to be paid to each production process. The entry of the glass is the starting step of tempering. Below, we will introduce the rules for the glass tempering furnace to be applied. We hope this will be helpful to everyone.

1. Glass tempering furnace loading rules

1.1. Equipment inspection: Before loading, the feeding roller table should be inspected and cleaned to maintain the cleanliness of the roller surface and prevent dirt from getting on the original glass sheet, which will affect the tempering effect and glass quality.

1.2. Check the original glass: In addition to the tempering furnace, there are also glass original pieces that affect the quality of tempered glass. The quality of glass original pieces directly affects the quality of tempered glass products. If there are defects such as burrs, poor grinding quality, etc., products cannot be processed in the furnace, otherwise it is easy to cause furnace explosion or pitting of glass.

1.3. Loading: During loading, the equipment should be paused and the glass room should be placed steadily at the front end of the loading roller to ensure that the position of the original glass sheet is correct. At the same time, pay attention to using the method of cross positioning and loading to avoid the phenomenon of "hot edge" caused by long-term high temperature and low temperature on both sides of the roller conveyor.

1.4. Turn on the device: Press the start button and wait for the glass to reach a step length before continuing to place the next piece of glass. The direct distance between glass sheets should not be less than 40mm, and the distance from the inner wall of the furnace should not be less than 50mm. The total length and swing amplitude should not exceed the length of the air grille. It is strictly prohibited to install excessively long sheets. In addition, the placement distance of thin and small glass original sheets should be increased, and the placement distance of large and thick glass sheets can be reduced.

1.5. Stopping the furnace: Before stopping the furnace, the loading of sheets should be stopped in advance to avoid the original sheets being stuck in the tempering furnace after stopping the furnace. After stopping the furnace, inspect the equipment and wait for the glass inside the machine to shake out before stopping all operations.

2. Precautions for glass tempering furnace lamination

2.1. Maintain hygiene: Ensure the cleanliness and hygiene of the loading table, and ensure that there are no dust or glass fragments or other debris on the roller conveyor of the loading table.

2.2. Maintain consistency in the texture and specifications of glass in the same batch: It is strictly prohibited to load glass raw materials with different thicknesses and translucency into the same tempering furnace. Glass with embossing, coating, spraying, and glazing requirements must have a smooth and clean surface facing downwards. The glass specifications and loading rates of each furnace should be as close as possible.

2.3. Principle of placement: Maintain a certain spacing when placing the film, and adopt the recommended loading rule of sequential cross change of position. Different specifications of glass with the same thickness and transparency can be assembled, and the position can be periodically changed and placed in the loading area.

2.4. Pay attention to the size of the glass plate: avoid malfunctions such as sticking the furnace door due to the length exceeding the glass size that can be accommodated by the tempering furnace.

The above is an introduction to the loading rules of glass tempering furnaces, hoping to help everyone better use the tempering furnace
