Fire Bricks
We supply dense refractory fire bricks for use in Kilns, Furnaces, Forges, Fireplaces or Wood Fired Pizza Ovens. Our Dense Fire Bricks are of the highest quality, made to strict dimensional tolerances, with smooth faces and sharp edges. With a minimum Alumina content of 38%, these bricks have a maximum working temperature of 1350 degrees C.
This Alumina content also makes these bricks very tolerant to Thermal Shock. Dense fire bricks are easy to cut, providing you have the right equipment.
High-Alumina Brick - up to 1735°C - 20mm thickness
Description A、Refractoriness 20mm high-alumina brick Refractoriness is higher than Clay brick and semi-silica brick,reaching 1750~1790℃，it’s the advanced refractory materials. B、Refractoriness under load The high alumina products is in the high Al2O3, less impurities, the formation of fusible glass less, so the load softening temperature than the clay brick, but the mullite crystallization doesn’t form a network organizations, therefore refractoriness under load ..
Light Weight Mullite Insulation Brick
Light Weight Mullite Insulation Brick Light Weight Mullite Insulation Brick, mainly based on aluminum silicate-based refractory materials, with some excellent performance, (especially high temperature creep performance) living in natural raw materials production Of the high aluminum products first. Mullite composition AL203 in about 79%, Si02 in 21% is more appropriate, but there are a certain amount of raw materials in the impurity composition, at high temperatures wil..
Lightweight Clay Insulating Brick
Lightweight Clay Insulating Brick be used as inner lining brick of industry kilns wall and industry furnance at working Temperature °C: > 1200 . The Lightweight Clay Insulating Brick is made of high purity fire clay, by adding combustible, gas evolution method, or foam method. Lightweight fire brick is a kind of porous material with Al2O3 content 30-46%. Its refractoriness is 1580-1750 ℃, refractoriness under load is 1250-1450 ℃, with good thermal resistance and strong abi..
What are the primary advantages of using dense refractory fire bricks in industrial applications?
Dense refractory fire bricks offer numerous advantages for industrial applications such as kilns, furnaces, and fireplaces. These bricks are designed with a minimum alumina content of 38%, allowing them to withstand maximum working temperatures of up to 1350 degrees C. Additionally, their high alumina content enhances their tolerance to thermal shock, making them ideal for environments with rapid temperature changes. Furthermore, their precise dimensional tolerances and smooth surfaces ensure a tight fit and durability in high-temperature applications.
Can dense fire bricks be easily modified for specific applications?
Yes, dense fire bricks can be easily modified to suit specific applications, provided that the right cutting equipment is used. Their composition allows for straightforward cutting and shaping, enabling engineers and technicians to create custom sizes and forms that fit particular furnace designs or kiln configurations. This flexibility is essential for optimizing the thermal efficiency of the setup.
How do dense fire bricks compare to lightweight clay insulating bricks in terms of thermal performance?
While both dense fire bricks and Lightweight Clay Insulating Bricks are suitable for high-temperature applications, they serve different purposes. Dense fire bricks are more suitable for areas that experience direct heat and require high thermal stability, with a working temperature exceeding 1350 degrees C. In contrast, lightweight clay insulating bricks are typically used as inner lining bricks in industrial kilns and furnaces, operating at temperatures above 1200 degrees C. The choice between the two depends on the specific thermal and structural requirements of the application.
