High Alumina Insulating Brick Sintered Mullite Insulating Fire Brick Light Weight Refractory Bricks

Product specifications This Series of mullite light-weight insulating brick with the bulk density 0.5-1.3g cm3 and service temperature 1250℃-1550℃,the formula of each product has different characteristics to meet the needs of different kilns and environmental conditions. Mullite insulating bricks using high purity raw material and then add filled combustible material according to the level of strict classification, when the combustible material is burning and then disappeared in high-temperature kiln burning process,the bricks will form uniform porosity structure. Each side of the brick can be machined to the customer required size to ensure the quality of the kiln. 1. Low thermal conductivity: good insulating effect; 2. Low hot-melting: due to low thermal conductivity,this series insulating bricks save little heat energy,which cause obvious energy-saving effect; 3. Low impurity content: low iron,low alkali metal and low oxide content;high refractoriness;and high aluminum content which makes it maintain good performance in reductive atmosphere; 4. High compressive strength under thermal states; 5. Accurate size: speed up the engineering speed, reduce the amount of refractory slurry, reduce the gap between the cracks, ensure the strength and stability of the masonry, and prolong the life of the furnace lining. 6. Can produce special-shaped products: ensure the design structure of the furnace; FAQ Q1: Are you a manufacturer or trader? A1: Factory+trade (We are the Refractory castable factory, at the same time, we operates other relate products) Q2: Can we visit your factory? A2: Sure, Welcome at anytime, seeing is believing.
