Source :    Release time:2013-09-05

During the glass tempering production by glass tempering furnace, different kinds of glass defects may be left on tempered glass due to some complicated reasons, which are difficult for the glass tempering furnace operator to identify the reasons and avoid the defects. However, during our long time customer service, Landglass has analyzed some common defects and provide customers with following practical solutions for avoiding or minimizing these defects, which can be also regarded as the replies to some technical questions from the customers.

3. Glass sheets bend upward or downward in one batch
Generally speaking, this situation is caused by uneven quenching due to the deformed nozzle blocks, such as:
1) The nozzles are not in same level which cause uneven quenching speeds at different part of glass sheets;
2) Some nozzles holes are blocked by dirt which causes no air or uneven quenching;

3) If there is no problem on nozzle blocks, then it may be caused by uneven heating in heating furnace.

1) Check the height of the nozzle blocks and make them at same height;
2) Clear the air nozzles and keep them clean;
3) Check if the current for heating and the thermal couples are right; replace the broken thermal couple with a new one so as to get right temperature feedback, thus, ensure even glass heating.
