The surfacing of wear-resistant parts re-manufactured combined with multidisciplinary theories of maintenance engineering, surface engineering, mechanics, tribology, and materials science, and therefore its technical means include both conventional maintenance technologies and surface engineering technologies as the main body, and the development of new technologies. Non-destructive testing, life assessment, quality control and other advanced technologies. Therefore, we have a lot of concrete and meticulous work to do in the development of wear-resistant materials and surfacing technology and technology. The performance of wear-resistant materials has always been a major issue that restricts the application of vertical mills. Although some materials have better hardness, ie, better wear resistance, but the impact toughness is poor, many roll sleeves have appeared after running for some time. That is the problem of cracking.
Today, wear-resisting composite plates are moving in the direction of composites with more comprehensive properties, and methods such as remanufactured remanufactured welding and reliable maintenance and extended life are emerging. At the same time, structural forms similar to DUOCAST roll sleeves have emerged. All of this The development and application of vertical grinding mills are constantly being promoted. It is predicted that steel consumption will reach 600 million tons by 2020, and mold steel consumption will reach 600,000 tons, of which wear-resistant mold steel accounts for 40%, ie, 240,000 tons, of which nm400 wear plates only account for 15%, and annual consumption is only 36,000. Tonne, Baosteel and Wugang each bear 20,000 tons. At that time, the import volume will be greatly reduced, and the export task will be mentioned on the agenda.
