| Abstract: | The work roll sleeve material for melted steel powder reclaiming rolling mill has been developed, the melted steel powder is from 4 kinds of different chemical compositions of Cr-Mo-V series material. Through the determination of the critical point and transition curve, filtration of the heat treatment process, deep cold quenching test and the analysis of the micro-structure and mechanical property, the optimized composition and the heat treatment process for the hot roll sleeve material have been defined. The results shows that this material has better hardenability, quenching degree, wearable performance and the better high temperature utility performance, the integration performance of which has been exceeded the similar product at abroad. |
