A refractory layer structure includes a plurality of refractory layers stacked on each other. Each of the refractory layers includes refractory bricks. Each of the refractory bricks is formed as a cuboid having a pair of oppositely positioned first diverging sides and a pair of oppositely positioned second diverging sides. The first diverging sides diverge away from each other from a top to a bottom of the refractory bricks. The second diverging sides diverge away from each other from the bottom to the top of the refractory bricks. The first diverging sides and the second diverging sides are connected to each other. Each of the first diverging sides have a first diverging side protrusion projecting from a top surface thereof. Each of the second diverging sides have a second diverging side protrusion projecting from a top surface thereof.
