Good Properties of K26 Insulation Fire Bricks
Good Insulation Effect
K26 insulation bricks have excellent thermal insulation properties and can effectively reduce heat conduction. This allows it to maintain a stable temperature inside the kiln, preventing heat loss and improving energy efficiency.
High Refractoriness
This product can withstand continuous use in high temperature environments. They can resist corrosion from factors such as high temperature, flame and chemical corrosion, and maintain stable performance.
High Strength
K26 refractory bricks with excellent mechanical strength can withstand a certain amount of pressure in kilns. Therefore, this makes K26 firebrick highly reliable in the masonry and support of lining of high temperature kiln and able to maintain structural integrity over long periods of time.
Good Thermal Shock Resistance
K26 thermal insulation refractory bricks have excellent thermal shock resistance. They are able to withstand the expansion and contraction of the kiln at high temperatures, reducing thermal stress due to temperature changes, thereby reducing the risk of cracking and damage to the bricks.
Common Applications of K26 Insulation Brick
K26 insulating refractory bricks are widely used as linings for casting furnaces, forging furnaces, ceramic furnaces or high-temperature parts in other industries. They can withstand smelting and heating processes at high temperatures, protect the furnace structure and reduce heat loss. These bricks have operating temperature ratings up to 2600 degrees Fahrenheit, making them the most recommended bricks for high fire ceramic uses.
