Description
Technical Field
[0001] The utility model belongs to the technical field of refractory bricks, and in particular relates to a hollow composite refractory brick. Background Art
[0002] Refractory bricks are bricks with excellent refractory properties at high temperatures and are widely used in industrial furnaces, kilns, heat treatment equipment and other fields. According to different preparation processes and shapes and sizes, they can be divided into many types. According to the preparation process, they can be divided into sintered bricks, unsintered bricks, fused bricks (electrically fused bricks) and refractory insulation bricks. According to the shape and size of refractory bricks, they can be divided into standard bricks, ordinary bricks and special bricks. According to the different Al2O3 content, refractory bricks can be divided into different types such as high-alumina bricks, dolomite bricks, magnesia-chrome bricks, spinel bricks, anti-stripping bricks and phosphate bricks. Among them, high-alumina bricks have higher refractoriness than clay bricks, good resistance to acid and alkali erosion, suitable for cement kiln firing zones, etc., and have a long service life. Although magnesia-chrome bricks have good kiln skin, they have poor thermal shock resistance. The current hollow refractory bricks have greatly reduced strength compared to solid refractory bricks, and are prone to breakage during construction. In addition, the existing refractory bricks have poor thermal insulation and heat-insulating effects, and some refractory bricks do not have the functions of thermal insulation and heat-insulating at all, so a new type of composite refractory brick is needed.
