Refractory clay bricks, fireproof clay bricks, or refractory clay bricks are blocks of refractory ceramic material used to line furnaces, kilns, fireboxes and fireplaces. Manufactured by Yutong, these bricks are primarily used to withstand high temperatures, but often also have a low thermal conductivity to improve energy efficiency. Our company manufactures and supplies these refractory bricks for steel, glass, furnaces and various other industries that require fire to survive. Ordinary bricks will not survive at such temperatures.
Yutong is a well-known manufacturer and supplier of high-quality refractory bricks. Refractory clay bricks are available in a wide range of shapes and sizes and many other shapes and sizes can be customized to meet customer/site requirements. Our high alumina refractory bricks / high-density refractory bricks are proven solutions for various industries for refractory applications in the temperature range of 1260 c - 1450 c and have been successfully used by different companies around the world.

Circle fireclay bricks are specialized fire bricks that are used to construct circular structures or lining in high-temperature environments. The circular shape of these bricks allows for smooth and continuous lining without the need for excessive cutting or fitting. This makes them more efficient to use in curved or circular structures, helping to ensure a reliable and durable construction in high-temperature environments. Applications of Circle Fireclay Bricks: Kilns: Circle fireclay bricks are commonly used to build the inner lining of kilns, which are used for firing ceramics, pottery, and other materials at high temperatures. Furnaces: In industrial settings, circle fireclay bricks are used to construct the interior of furnaces, which are used for melting metals or processing other heat-intensive materials. Chimneys: The circular shape of these bricks makes them ideal for constructing chimneys and flues, where they can withstand the high temperatures and corrosive byproducts of combustion. Forges: Circle fireclay bricks are also used in blacksmith forges, where they create a heat-resistant lining to contain the intense heat needed for metalworking. Pizza Ovens: In traditional pizza ovens, circle fireclay bricks are often used to line the cooking chamber, as they can endure the high temperatures required for baking pizzas.
Fireclay bricks are mainly made from chamotte, being high pressure pressed and sintered in high temperature. Main minerals compositions are mullite phases. These products are widely used in all parts of furnace lining for middle and small capacity blast furnaces because of their excellent physical and chemical properties in high temperature. It also can be used in lining for other kinds of furnace.
