Paper Title:
Research on Hardening the Surface of Laser and Anti-Tempering Property of Cast Steel Hot Roller
  Abstract

Fine martensite could be gained in 70Mn2Mo cast steel roller after solidification by laser treatment. The hardness and depth of hardened zone reached 920 HV (about 65HRC) and 0.6mm respectively. After tempered in high temperature, the depth of hardened zone whose hardness was maintained above 430HV was 0.4mm. These results showed the better anti-tempering property and the higher hardness and hardened depth compared with water quenching and implied the greater applied potentiality of laser strengthening.
