Refractory concrete is a type of refractory concrete made by pouring a mixture of aggregates, binders, and admixtures in the required proportions.
According to different binders, refractory concrete can be divided into aluminate refractory concrete, sodium silicate refractory concrete, phosphate refractory concrete, and aluminum sulfate refractory concrete.
Refractory concrete has been widely used in the lining, doors, walls, and steel tapping slots of heating furnaces, soaking furnaces, and other industries such as metallurgy, chemical, petroleum, light industry, and building materials, as well as in structures that are exposed to high temperatures for a long time, such as the lining of industrial chimneys or flues, the refractory lining of industrial kilns, and the foundation and shell of high-temperature boilers.
Compared with traditional refractory bricks, refractory concrete has the following characteristics:
1. The production process is simple, usually only requiring a mixer and vibration forming machinery;
2. Simple construction and easy mechanization;
3. Multiple structural forms of kilns can be constructed, and complex kiln forms can be constructed according to production process requirements using heat-resistant concrete;
4. The heat-resistant concrete kiln lining has strong overall integrity, good airtightness, and proper use, which can improve the service life of the kiln;
5. The cost of building a kiln is low;
6. It can fully utilize industrial waste, waste refractory bricks, as well as certain local and natural materials.
