The service life of the existing brick is very short in a metallurgical furnace, a heating furnace and a high-temperature liquid container, the brick generally starts to be damaged and broken until the brick completely falls off within 6 months to 3 years after the metallurgical furnace, the heating furnace and the high-temperature liquid container are opened, and then a cooling wall forms a furnace shape by cooling molten slag iron to form a slag crust, protect the hot surface of the cooling wall and reduce the heat loss. However, the slag crust has low strength and often falls off, and a certain time is needed for formation. During the period of slag crust falling, the temperature of the hot surface of the cooling wall is very high, and the cooling wall is exposed in the direct abrasion of liquid iron slag, high-temperature airflow and furnace burden, and cracks are generated on the hot surface of the cooling wall and are expanded until the cooling wall is damaged. The short life of the brick is also the main reason of the short life of the cooling wall. Because the temperature of the hot surface of the cooling wall cannot exceed the limit value if the brick is protected by the brick, the cooling wall cannot be directly corroded by the slag iron and the high-temperature coal gas flow and cannot be basically damaged.
The cause of the brick-inlaid damage is not thoroughly researched, and the cause of the brick-inlaid damage of the cooling wall is generally mentioned: 1. erosion of the molten slag iron and the furnace gas to the refractory material; 2. under the action of high temperature, the refractory material is damaged by reaction, such as volume effect caused by phase change generated by the generation of new minerals and volatilization under the action of vacuum; 3. the scouring and the erosion of the molten slag iron on the refractory material; 4. the thermal shock caused by the repeated action of the molten iron slag and the high-temperature coal gas on the refractory material causes the cracking and the peeling of the refractory material; 5. damage caused by the thermal expansion effect of the refractory itself; 6. improper selection and matching of refractory materials; 7. misuse of the refractory material. Such as improper masonry mode and baking mode.
In view of the above, the applicant has found that the main cause of the damage of the cooling stave bricks is the excessive and concentrated stress generated after the bricks are thermally expanded, thereby causing the bricks to be damaged.

10. The stave of claim 9, wherein a refractory filler is provided in the first compensation gap; and/or the presence of a gas in the gas,
a refractory filler is arranged in the second compensation gap; and/or the presence of a gas in the gas,
and a refractory filler is arranged in the third compensation gap.
11. The stave of claim 7 wherein the hot face defines a mounting recess adapted to the mounting portion, the mounting portion being disposed within the mounting recess; and/or the presence of a gas in the gas,
the material of the attachment wall is a metal material; and/or the presence of a gas in the gas,
the attached wall is provided with a cold surface opposite to the hot surface, the cooling wall comprises a cooling pipe arranged in the attached wall, cooling liquid flows in the cooling pipe, and an inlet and an outlet of the cooling pipe are arranged on the cold surface.
12. A high temperature furnace comprising the stave of any one of claims 7 to 11.
