[0002] As an important material in high temperature industry, the quality and performance of refractory bricks have a great impact on the operating efficiency and life of high temperature equipment. In the production process of refractory bricks, annealing and cooling is a key link, which directly affects the final performance of refractory bricks.

[0003] The existing method usually places the sand mold templates side by side in an insulation box. Since the sand molds are adjacent to each other, the heat dissipation efficiency of the adjacent surfaces of the two adjacent sand molds is slower than that of other surfaces of the sand mold templates, which leads to uneven temperatures on all sides of the sand mold templates. In addition, although some annealing cooling devices are provided with heat conduction mechanisms between two adjacent sand mold templates, the heat conduction mechanisms are complex in structure and independent of each other, which still makes it inconvenient to realize that the sand molds have relatively synchronized temperature steps, thereby reducing the molding quality of refractory bricks. Summary of the invention
