Light Weight High Alumina Brick High Refractoriness For Furnace
Description
Lightweight high alumina bricks are commonly used in furnaces due to their excellent thermal insulation properties and high refractoriness. These bricks are made from high-quality raw materials such as high alumina bauxite and other refractory materials, which are mixed with a binding agent and molded into bricks.
One of the main advantages of lightweight high alumina bricks is their low thermal conductivity, which helps to reduce heat loss and improve energy efficiency in furnace applications. They also have high compressive strength and good resistance to chemical attack and abrasion, which makes them ideal for use in high-temperature environments.
