慮して決定されるべきである。In the brick according to the present invention, the cross section of the flow path of the brick body is substantially triangular. Specifically, the shape of the three corners inside the brick body is rounded (see FIGS. 1 and 3) or each is 60 degrees or more (see FIG. 2). Also, the shape of the three outer corners of the brick body may be rounded (see FIG. 3) or may be 60 degrees or more, preferably 120 degrees (see FIG. 4). These shapes should be determined in consideration of formability, thermal stress during use, and the like.
