What are the material requirements for the production process of breathable bricks?

Breathable brick is an important refractory material with good refractory performance and is widely used. The breathable brick is made of tabular corundum, spinel, chromium oxide and other materials, which are formed, fired and assembled. Its characteristics are high strength, Erosion resistance, corrosion resistance, high air permeability, suitable for various ladle applications. Especially the newly developed breathable bricks containing nitride materials have good corrosion resistance, are not easy to penetrate steel, and have high blow-through rate. They are a new generation of breathable brick products. .In addition, the construction of the breathable brick is convenient, the surface is evenly painted with fire clay, and the installation is stable.

Now the breathable brick is an essential functional element outside the furnace. With the progress of the production process of the breathable brick, it is developing in the direction of safety and reliability, uniform ventilation, good precision control performance, strong resistance to melting loss, and long service life. The material requirements are mainly in the following aspects.

1. The breathable brick material requires excellent air permeability.

2. Breathable brick is an important refractory material, so the material also needs good refractoriness, and the refractory temperature should meet the requirements of the regulations according to the needs of customers.

3. The breathable brick material has excellent thermal shock resistance and shedding resistance.

4. The breathable brick material has excellent oxidation resistance.
