摘要： PROBLEM TO BE SOLVED: To provide a tough for molten iron and/or slag, which can further improve its durability and extend its life.
SOLUTION: The tough 1 for molten iron and/or slag is directed for passing the molten iron and/or the slag therein tapped out from a blast furnace, and includes: a refractory layer 23 having an excurrent groove passage 20 which has a groove shape and passes the molten iron and/or the slag therein, and having a discharge port 21 which is provided in a downstream side of the excurrent groove passage 20; and a shaped brick portion 3 which is embedded in a backside of the downstream area of the excurrent groove passage 20 out of the refractory layer 23 and contains silicon carbide as a principal component. In the shaped brick portion 3, the downstream end face 31 in the direction along which the molten pig iron flows through the excurrent groove passage 20 is exposed to an external part A.
