Three-low bricks refer to low porosity, low iron and low creep. They are made of high-quality raw materials, three-stone raw materials, ultra-fine composite powder and specific additives through high pressure forming and high temperature sintering. They have strong high temperature corrosion resistance and medium and high temperature creep rate. high compressive strength and high refractoriness under load.

Low Porosity Clay Bricks Characteristics
1. Low apparent porosity and strong compactness.
2. Good permeability and erosion resistance.
3. High temperature strength and long service life.

Uses and Requirements of Low-porosity Clay Bricks for Glass Kiln
Low-porosity clay bricks are mainly used in the regenerator of the glass kiln. It can also be applied to blast furnaces, hot blast furnaces in the iron and steel industry, cement kilns in the building materials industry, and chemical kilns in the chemical industry, as kiln linings. In the industrial field, the use of low-porosity clay bricks in high-temperature furnaces in steel, glass, chemical and other industries is becoming more and more common. Therefore, the requirements for the physical and chemical indexes of low-porosity clay bricks are becoming more and more stringent.

The complexity and dimensions of modern high-temperature kilns far exceed traditional designs, and the requirements for physical and chemical indicators of low-porosity clay bricks also greatly exceed national and industry standards. In order to extend the service life of high-temperature kilns and meet the needs of users, the physical and chemical indexes of low-porosity clay bricks for high-temperature kilns reach the desired value. Refractory manufacturers need to solve the defects of low-porosity clay bricks due to the differences in the quality of refractory raw materials, unreasonable size distribution, excessive iron content, and poor quenching and rapid heating properties.
