JHY-1C carbide hardfacing welding rod of high impact 
 An important international impact of the invention, the impact resistance is 16 times Mn13. Tianjin Cement Design & Research Institute in 1988 designed China's first large-scale single-stage hammer crusher hammer the core components of the rotor disk, first time was a success, has been surfacing hundreds, the rotor 3 to 4 years of life, greatly improve the technical level of large equipment. The reactor 212 (5Cr5Mo4), W9Cr4V other life only a few months, a shorter reactor 186, are migrating to JHY-1C surfacing. JHY-1C welding hammer is the only successful international products: welding layer is not broken do not peel, and constantly hammer, 6 ~ 8mm thick crushed more than the high manganese, high manganese wear 60 ~ 70mm hammer crushed when the amount of life increased from 0.8 to 3 times, several years of large-scale application Cement Group proved to be the oldest hammer. This study by the American Welding Society. With the Swiss Castolin_Eutectic1996 Annual International Prize "award in welding, welding, maintenance welding of the most outstanding achievement." China for the first time, the only award. 1988 roller press welding electrodes welding with JHY-1C rigid roller machine, roller surface without surfacing from the working life of 7 days to 1 year. 1993 by JHY-1W (62HRC) surfacing Humboldt first roller press, the life increased to the original roll 6000h 6600h, the company's welding expert Marcos vertical thumb appreciated.
