The weight of a refractory brick is determined by its bulk density, while the weight of a ton of refractory bricks is determined by its bulk density and quantity. In addition, the density of different types of refractory bricks is different. So how many types of refractory bricks are there? How many degrees of high temperature can they withstand? Is there a big price difference?
1. What is the density of refractory bricks?
The density of silica bricks is generally 1.80~1.95g/cm3
The density of magnesia bricks is generally 2.85~3.1g/cm3
The density of alumina-magnesia carbon bricks is generally 2.90~3.00g/cm3
The density of ordinary clay bricks is generally 1.8~2.1g/cm3
The density of dense clay bricks is generally 2.1~2.20g/cm3
The density of high-density clay bricks is generally 2.25~2.30g/cm3
The density of high alumina bricks is generally 2.3~2.7g/cm3
For example, T-3 refractory bricks have a specification of 230*114*65mm.
The body density of ordinary clay refractory bricks is 2.2Kg/cm3, and the weight of T-3 refractory bricks is 3.72Kg;
The body density of LZ-48 high alumina bricks is 2.2-2.3Kg/cm3, and the weight of T-3 refractory bricks is 3.75-3.9Kg;
The body density of LZ-55 high alumina bricks is 2.3-2.4Kg/cm3, and the weight of T-3 refractory bricks is 3.9-4.1Kg;
The body density of LZ-65 high alumina bricks is 2.4-2.55Kg/cm3, and the weight of T-3 refractory bricks is 4.1-4.35Kg;
The body density of LZ-75 high alumina bricks is 2.55-2.7Kg/cm3, and the weight of T-3 refractory bricks is 4.35-4.6Kg;
The density of special-grade high-alumina bricks is generally greater than 2.7Kg/cm3, and the weight of T-3 refractory bricks is 4.6-4.9Kg.
