U85 mining coal and rock pick, JZA80/30 A kind of pick shaped pick of series shearer. 废柴视频网 最新地址_最爽爱爱高潮免费视频_情侣自拍女上位5g天天爽. It is a cutting tool for directly breaking rock and coal on shearer. It is mainly used for cutting coal and rock, usually with U85 Tooth sleeve U85 The tooth base is installed on the matching drum of shearer.
The performance of u85 pick directly affects the production capacity, power consumption, working stability and the service life of other related parts.
1 U85 Basic information of pick
1. Shape: pick shaped pick, slim body design. Inlaid with the latest cemented carbide, it has the characteristics of strong permeability and high cutting efficiency in coal mining operation.
2. Size: tooth length 80mm Diameter of left and right shank and toothed shank 30mm about.
3. Wear resistant layer: through plasma cladding strengthening technology, the U85 The width of one layer of cladding on the head of pick is about 20~30mm , thickness 2~3mm The annular belt. It can prevent the wear of alloy body and maximize the use of alloy head.
2 U85 Technology of pick
1. Forging: cold extrusion precision forging process
2. Heat treatment process: quenching and tempering temperature and time are the best scheme for independent research and repeated test; It is precisely controlled by computer, and a three-stage temperature real-time monitoring feedback system is added to ensure the stability and uniformity of temperature. The pick has the characteristics of high hardness, uniform hardness and better wear resistance.
3. Production process: U85 The pick is produced by the domestic advanced automatic brazing and quenching integrated production line, which integrates cleaning treatment, alloy welding, tooth body quenching, overall tempering and overall anti rust treatment.
4. Anti rust treatment process: it has the equipment to automatically complete the processes of pick transmission, anti rust liquid spraying, surface drying, etc., and finally forms an effective anti rust layer on the surface of the pick, which can ensure that the surface of the product will not rust after long-term storage.
5. Testing technology: it has professional instruments to detect the surface quality, internal and external hardness, welding plumpness, etc. independent inspection room and advanced monitoring equipment, including hardness tester, metallographic analyzer and two position measuring instrument, to ensure 100% High quality.
