[0019] Figures 1 to 5 It is the best embodiment of the utility model, and the following Figures 1 to 5 The utility model is further described.

[0020] Reference Figure 1 The precast brick includes a precast brick body 1 and a stainless steel embedded part 2. The stainless steel embedded part 2 is arranged inside the precast brick body 1 and one side of the stainless steel embedded part 2 exceeds the precast brick body 1. The exceeding part is a welding part 204. The thickness of the welding part 204 is 5-15mm. Bolt holes 3 are arranged at both ends of the stainless steel embedded part 2, and an avoidance groove 4 is arranged at the position of the precast brick body 1 corresponding to the bolt hole 3.

[0021] Reference Figures 2~4Specifically, two stainless steel embedded parts 2 are embedded in a rectangular precast brick and arranged along the length direction of the precast brick body 1. The stainless steel embedded part 2 is provided with a stainless steel embedded part body 201 and a connecting part 202. The connecting part 202 is arranged on the side of the stainless steel embedded part body 201 away from the welding part 204. The stainless steel embedded part body 201 is rectangular, and bosses 203 are provided at both ends protruding outward. The width of the boss 203 is smaller than the width of the middle body, and the bolt hole 3 is arranged on the boss 203.

[0022] The portion of the stainless steel embedded part body 201 that extends beyond the prefabricated brick body 1 is a welding portion 204, which is welded and fixed to the coke tank shell.

[0023] In this embodiment, the middle of the connecting piece 202 is connected to the stainless steel embedded part body 201, the two sides of the connecting piece 202 are inclined, and the two ends of the connecting piece 202 are bent and parallel to the stainless steel embedded part body 201. The connecting piece 202 makes the precast brick body 1 and the stainless steel embedded part 2 better combined, making the fixation of the precast brick and the shell more stable.

[0024] Four semicircular avoidance grooves 4 are arranged on both sides of the long sides of the precast brick body 1 corresponding to the positions of the bosses 203, and the bosses 203 are arranged in the avoidance grooves 4. After the stainless steel embedded parts 2 are welded to the shell, the bolts pass through the bolt holes 3 on the stainless steel embedded parts 2 and are installed in the bolt holes corresponding to the shell, so that the precast bricks are more firmly installed on the coke tank shell. Compared with ordinary precast bricks, the precast bricks of the utility model are fixed to the shell by two connection methods, which is more firm. The stainless steel embedded parts 2 and the precast brick body 1 are better combined together through the connector 202, and the overall anti-stripping effect is enhanced, which increases the service life of the precast bricks.

[0025] The two opposite sides of one end of the precast brick body 1 have a first chamfer 6 and a second chamfer 7 respectively, wherein the first chamfer 6 is arranged on the opposite side of the stainless steel embedded part 2, and the length of the first chamfer 6 is greater than the length of the second chamfer 7, so as to facilitate the red coke to roll onto the gate.
