Maintenance of scraper of Anhui mining machinery

1. Scraper sprocket, whether rable, depends on the quenching equipment
most sprocket quenching methods are high frequency quenching. But this kind of quenching is more troublesome, need a tooth a tooth quenching, relatively slow; Even worse, the hardness gradient of quenching is not suitable. Gears are easily damaged
the better quenching method is flame quenching, and the hardness gradient of flame quenching is the most ideal. But the difficulties are uniformity and speed. To solve this problem, we need to use CNC and automatic quenching equipment
the automation equipment has been used in Shanxi coal machinery and Shandong mining machinery. The effect is quite good, which can completely replace the similar imported equipment from Germany
please look at the video file and search for the video "automatic NC flame quenching machine tool" on the Internet.

2. There is no way to repair the scraper
