[Zhongbo.com] When using a continuous hot bending furnace to heat a variety of glass in the same furnace, the order of the furnace should be arranged according to the size, area, shape and thickness of the glass, that is, the glass bending in the adjacent position. The principle of time is as close as possible to arrange the order of the glass into the furnace. Specifically speaking, according to the length of heating of the glass hot bend, the film starts from the shorter time, and gradually puts into the glass with a slightly longer hot bending time, and then increases in increments. When the total number of cars is half, the heat is sequentially loaded. The bending time is successively decreased, and the hot bending time of the post-loading glass is similar to that of the previous loading glass. Alternatively, the glass that has been heated for a long time in the hot bend is placed in the order of decreasing time, and then placed in the order of half of the total number of vehicles, and then sequentially placed in the same order, and also required to be placed in the glass and previously placed in the glass hot bend. Time is as close as possible.
The reason for this arrangement is that the continuous hot bending furnace is continuously produced, and there is a multi-stage preheating chamber. During continuous production, the hot bending time of the front glass is the preheating time of the later type glass in a preheating chamber of a certain stage. If it is not discharged in the above order, when the large glass is bent, the adjacent glass will be preheated and overheated. On the contrary, when the small glass is hot-bent, due to the short time, the pre-heating of the adjacent large glass will be insufficient. This affects the quality of the glass and even causes the glass to be scrapped or broken. According to the above method, the adjacent glass hot bending heating time is similar, which can be regarded as approximately equal. The heating time is gradually changed according to the order of entering the furnace. Different types of glass will not interfere with each other due to different bending time. Guaranteed hot bending quality and yield.
