Quartz ceramic roller is used in driving roller of glass tempering furnace. It has high temperature resistance and high surface quality, which can effectively guarantee the quality of glass products. The transmission mechanism adopts O-belt and linkage synchronous belt, which greatly improves the transmission accuracy, reduces the impact of the vibration of the transmission system on the ceramic roller, eliminates the deviation, and reduces the scratches caused by synchronous transmission to a low point. Convection steelmaking furnace is mainly heated by convection mode. The top of the furnace is equipped with special high temperature fan. Convection box and high performance special heater are installed in the furnace. There are more heating zones and more uniform temperature in the furnace. The surface power of heating elements is low, and the thermal shock resistance is good, and the service life is longer. The cooling grille is divided into two parts, the upper part and the lower part, which are connected with the air distribution center respectively. According to the different thickness of glass, the distance between windshield and glass can be adjusted automatically, so that the spray distance is always in good condition and the strength and uniformity of tempered glass can be guaranteed. In addition, the human-machine interface of the minitype steelmaking furnace is convenient, and all the process parameters can be pre-set and changed in the control process. The process parameters of glass with different thickness are input, stored and invoked in order form, which is convenient and reliable. So how to identify the stress line of tempering treatment? Glass tempering furnace manufacturers for you to introduce.

1. Basis for identification

According to the characteristics of tempering process, the stress of tempered glass is not uniform. The manufacturer of glass tempering furnace indicates that the stress line of tempered glass surface can be easily identified by the strengthened glass tester. Therefore, the strengthened glass tester can be used to identify whether the glass has been tempered or not.

2. Identification process

Take the glass that needs to be identified, place the strengthened glass tester on the glass, make it close to the surface of the glass (for easy observation, the other side of the glass is suggested to be a black background). Open the tester switch, and observe the bright shadows on the glass surface from the front of the observation port. Each surface of the glass will appear. Shadows of Liliang.

　　玻璃钢化炉厂家表示，若该玻璃为单片玻璃，则会出现两列亮的影子，在玻璃表面滑动鉴定仪，密切关注两列颜色的变化，若第2列影子的颜色与前列相比发生了不同的变化，则意味着鉴定仪检测出一条应力线，该玻璃经过钢化处理，若两列影子没有颜色变化或同时改变颜色，则该玻璃未经过钢化处理。

　　若是由两片玻璃组成的中空玻璃，则会出现四列亮的影子。从观察口的正面看，从右向左依次为前列、第2列、第3列、第4列。前列和第2列反映的是鉴定仪接触的玻璃的影子，第3列和第4列反映的是另一面玻璃的影子。

3. Applicability and limitations

(1) Applicability: Glass tempering furnace manufacturers say that this method can easily identify whether glass has been tempered or not, especially for hollow glass consisting of two pieces of glass, which can easily identify the location of tempered glass. At the same time, because this method is non-destructive test, it is widely used in practical engineering. Generalized application.

(2) Limitations: Automotive glass tempering furnace manufacturers said that this method must be closely attached to the surface of the glass, which brings inconvenience to the identification of glass that is not easy to be touched.
