Abstract

There is provided a method for assessing a slab, which method can determine, based on component concentrations in molten steel manufactured by a continuous casting machine, the risk that a slab manufactured from the molten steel will split into two pieces. A method for assessing a slab containing Ti, C, Si, and Mn as components and manufactured using a continuous casting machine includes a first step of determining the index of a liquid fraction of scale formed on the slab using component concentrations in molten steel poured into a mold of a continuous casting machine, and a second step of determining that the slab is at risk of splitting into two pieces when the index of the liquid fraction of the scale is greater than or equal to a predetermined threshold value.
