Abstract
The formation of cracks in a funnel mold for casting of thin slabs was studied using metallographic studies and mathematical models. It was found that the initiation of crack is associated with the formation of brittle compound relative to the matrix. Scale deposition at the slot just below the meniscus increased the hot face temperature of copper plate. The slot depth of funnel mold has variable distance from the hot face and the range of slot-depth is 25-28mm in the funnel transition area. By removing the tension bolt near the crack occurrence region, service life of copper plate increased 3 times, indicating that stress concentration is the main cause of copper plate cracks.
