Korean J. Met. Mater. 2020;58(1):17-25.   Published online 2019 Dec 12
DOI: https://doi.org/10.3365/KJMM.2020.58.1.17

Abstract
Studies of effective furnace cooling technology and refractory materials have extended the lifetime of a blast furnace to more than 15 years. On the other hand, the replacement of refractories in the blast furnace results in considerable cost and time loss for stopping the blast furnace operation. Various kinds of.....
