Abstract

The invention relates to a refractory brick consisting of a small refractory body (a) having the general shape of a regular hexagonal prism, having a horizontal upper end face (d), a horizontal lower end face (e) and six vertical peripheral walls (f), the horizontal plane being a regular hexagon consisting of 24 equal equilateral triangles, viewed from the top view of the upper end face (d), in such a way that the upper end face (d) and the lower end face (e) form a regular hexagon, and the lower end face (e) and the six vertical peripheral walls (f) form a regular hexagon. Among the 19 vertical channels (1), six channels have one-third channel cross sections at the contact positions between the vertical peripheral walls (f), the other six channels have one-half cross sections in the middle of each vertical peripheral wall (f), and the other seven channels have complete cross sections, are placed in the small refractory body (a), so that a central vertical channel (1.1) is formed, and the other six vertical channels (1) are uniformly distributed around the central vertical channel (1.1). The invention is characterized in that the common equivalent dimension reference of all 19 vertical channels (1) of the small refractory body (a) is a circle, the equivalent value of the horizontal cross section of which is a certain radius, the radius of the reference circle preferably being between 5 and 25 millimeters, according to which the distance between the two channels is equal, and the distance between each channel and the central vertical channel (1.1) is equal. The 19 vertical channels (1 and 1.1) are divided into at least three types, so that the arrangement rule of the vertical channels (1 and 1.1) on the upper horizontal plane (a) is that the equivalent values of all the vertical channels (1 and 1.1) on the upper horizontal plane (a) are 5-25mm, and the equivalent values of all the vertical channels (1 and 1.1) on the lower horizontal plane (a) are 5-25mm. The arrangement rule of the vertical channels (1 and 1.1) on the upper horizontal plane (d) of the small refractory body (a) is the same as any vertex of each equilateral triangle forming the upper horizontal plane (d) or the lower horizontal plane (e) of the small refractory body (a), is located at the center of each vertical channel (1) of one of the at least three-dimensional categories, and is different from the other two-dimensional categories corresponding to the other two peaks. The method is published together with Figure 1.
