Abstract
In order to produce ADI casting with tensile strength more than 1 400 MPa and the yield strength more than 1 100 MPa stably, firstly choosing highgrade charging materials, nodulizers and inoculants, and using multi-inoculation technique, thereby the high-class chain wheel rough castings were obtained. Then, the quenching oil with 320 ℃ of flash point was used, and the austempering process including pretreatment at 780 ℃, holding 2 h at 920 ℃ and quenching 3 h at 240 ℃ was adopted. Finally the metallurgical structure and mechanical properties of the ADI casting meet the quality requirement.关键词
