REFRACTORY PRODUCT FOR USE IN CONTINUOUS CASTING, AND REFRACTORY PRODUCT MEMBER
The present invention improves corrosion resistance and thermal shock resistance of a zirconia-carbon based refractory product and refractory member for continuous casting. The refractory product according to the present invention contains a free carbon component in an amount of 8% by mass to 16% by mass, and a remainder in which a main component is a zirconia component, wherein a content of other component than the free carbon component and the zirconia component is less than 5% by mass in total. When a remainder after excluding a composition comprised of the free carbon component from a composition of the refractory product is defined as 100% by volume, refractory particles having a particle size of greater than 0.3 mm account for 5% by volume or more, and refractory particles having a particle size of 0.045 mm or less account for 5% by volume to 40% by volume, and an approximately continuous void layer is present around each of a plurality of coarse particles, at least one of which has a largest particle size among refractory particles in the refractory product. The refractory product has an apparent porosity of 16% or less, and a maximum thermal expansion rate at a temperature up to 1500°C is 0.6% or less.
