There are many types of refractory bricks, and there are also lightweight refractory brick products with different densities, but they are characterized by low density, high porosity, low thermal conductivity and good thermal insulation. what is it?
Refractory bricks can be used as high-temperature building materials and structural materials for kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures.
Lightweight refractory bricks generally refer to refractory bricks with a density of less than 1.3x103kg/m3 and good compressive strength, which are widely used in heat treatment equipment.
It is mainly used for the heat storage loss of industrial kiln masonry and the heat dissipation loss of the furnace body surface, generally accounting for about 24-45% of the fuel consumption. The use of light bricks with low thermal conductivity and low heat capacity as the structural material of the furnace body can save fuel consumption. At the same time, the furnace can be heated and cooled quickly, which improves the production efficiency of the equipment. The weight of the furnace body is reduced, the structure of the furnace body is simplified, the product quality is improved, the ambient temperature is lowered, and the working conditions are improved.
Lightweight refractory bricks have many advantages, but the choice is based on the specific application. In addition, lightweight fire-resistant bricks have low mechanical strength and cannot be used in load-bearing structures. In addition, it cannot be used on parts that come into contact with the charge and are heavily worn.
