摘 要: | 0IntroductionHot-rollers and scissors are the critical parts of thesteel rolling equipments.At present,the surface soften-ing,the early wearing and the tearing are the primary rea-sons for the lowservice life of the hot-rollers and scissors.Although hardfacing has been applied to repaire the partseasily being worn and torn,such as the hot-rollers and thescissors,and has been obtained economic benefits[1-3],this technology has common problem:if the hardfacing lay-er contains more excessive allo…
