Description

Technical Field

[0001] The utility model relates to the technical field of fused bricks, in particular to a high temperature resistant fused brick. Background Art

[0002] Fused bricks are a special-purpose refractory material, mainly made of raw materials such as zirconium aluminate, zirconium oxide, and aluminum oxide. This type of brick is usually used for the lining of equipment such as high-temperature industrial kilns and smelting furnaces, and can withstand corrosion and thermal shock at extremely high temperatures. Fused bricks are widely used in metallurgy, glass, cement and other industries because of their excellent temperature resistance and fire resistance. It can maintain stable physical and chemical properties under high temperature conditions, is not easily affected by thermal stress and corrosion, and ensures the normal operation and service life of the equipment. By using fused bricks, industrial production equipment can operate stably in high temperature environments, thereby improving production efficiency and product quality. Fused bricks are widely used in metallurgy, glass, cement and other industries, supporting the normal operation of these industries and are of great significance to the entire industrial production.

[0003] Although fused bricks have good fire resistance at high temperatures, they are easy to break when subjected to severe impact or vibration. The handling and placement of materials during regular use can easily cause the fused bricks to break, and after long-term use, the fire resistance of the fused bricks will gradually decrease, requiring regular replacement or repair. Most of the existing smelting furnaces have fused bricks built inside. If a brick breaks or needs to be replaced due to insufficient fire resistance, it is inconvenient and often requires the target brick to be carefully broken and then rebuilt, which is not only inefficient but also prone to the risk of surrounding bricks breaking.

[0004] In view of this, we propose a high temperature resistant fused brick. Utility Model Content
