Product Description
Product Description of Low Thermal Conductivity High Quality Fireclay Brick Sk32 Sk34 Sk36 For Blast Furance
Fireclay bricks are a type of clay product made from aluminum silicate materials with an Al2O3 content of 30% to 40%. Their refractoriness is up to 1690 to 1730 degrees Celsius. The main mineral composition of fireclay bricks is kaolinite (Al2O3·2SiO2·2H2O), with impurities of 6 to 7%, such as potassium, sodium, calcium, titanium, and ferrous oxide.
Fireclay bricks are a slightly acidic refractory product that can resist acid slag and gas erosion.
Product Features of High Quality Fire Clay Bricks
High refractoriness: Fireclay bricks can withstand temperatures of up to 1730°C (3146°F).
High strength: Fireclay bricks are strong and durable, and can withstand high compressive loads.
Low thermal conductivity: Fireclay bricks have a low thermal conductivity, which means that they heat up slowly and cool down slowly. This makes them ideal for use in applications where it is important to maintain a stable temperature.
Good resistance to chemical attack: Fireclay bricks are resistant to attack by most chemicals, including acids and alkalis.
Low shrinkage: Fireclay bricks have a low shrinkage rate, which means that they will not deform or crack when subjected to high temperatures.
