These cracks form on the surface of a DC cast ingot just above the impingement point of the secondary cooling water jets. The collaborative research resulted in several major accomplishments or findings: (1) Surface cracks were shown to be a result of hot tearing rather than cold cracks, as was thought before this project. The research team went to two industrial plants to measure temperature distributions in commercial 60,000-lb DC casting ingot. The industrial partners provided guidance, facilities, and experience to the research team. During the four-year project, 16 quarterly meetings brought the industrial partners and the research team together for discussion of research results and research direction. The project involved close collaboration among private industries, national laboratories, and universities. A successful four-year project on the modeling and optimization of direct chill (DC) casting to reduce ingot cracking has been completed. ![]()
