Abstract：After adjusting No.3 slab caster of Laiwu section steel, more cracks in the triangle zone and centerline appeared.Based on process conditions and equipment parameters, superheat of the molten steel in the tundish, parameters of nozzles from foot roller, the vertical-section and segment were analyzed. Approprite measurements were taken to optimize the cooling parameters. Through the continuous practice of production, the cracks in the triangle zone and the center line have been effectively controlled.
