Introduction to K23 Mullite Fire Bricks

K23 mullite fire bricks are commonly used for high temperature applications, and their melting point is usually between 1600°C and 1800°C.

Features of K23 Mullite Fire Brick Insulation Brick

1. Good thermal insulation properties: Thermal insulation brick K23 has low thermal conductivity, which can effectively reduce thermal conductivity and provide excellent thermal insulation effect.
2. A light weight: K23 thermal insulation bricks have a relatively low density and light weight, making them easier to carry and install.
3. Heat resistance: K23 mullite fire bricks can withstand higher temperatures, typically 1350°C to 1430°C.
4. Chemical corrosion resistance: K23 mullite fire bricks have good corrosion resistance to some acids, alkalis and other chemical media.
5. Ease of processing: K23 mullite insulation bricks can be cut easily, drill and install according to application requirements of various shapes and sizes.

Raw material composition of mullite insulation brick

• High purity mullite: mullite – ore mineral with a high melting point and good refractory properties, and its main components are silicon dioxide (SiO2) and aluminum trioxide (Al2O3). High purity mullite is one of the main components of K23 insulation brick.
• Binder: To give K23 insulating brick a certain structural strength and stability, it is usually necessary to add a certain proportion of binder. Common binders include high temperature refractory cement, high temperature fireproof adhesive etc.
• Other Supplements: To further improve the performance and processing technology of K23 insulating bricks, small amounts of other substances are sometimes added, such as anti-corrosion agents, modifiers, etc..

For which industrial furnaces are mullite insulating bricks K23 used??

Mullite insulation bricks are mainly used in the body and bottom of blast furnace, top of a hot blast furnace, glass furnace regenerator, oil cracking system lining, ceramic oven, etc.. Currently, it is widely used in the lining of shuttle furnaces, roller kilns, glass and petrochemical furnaces.
