Refractory bricks are a special type of construction material used in high-temperature environments such as furnaces, kilns and fireplaces. These bricks are made of refractory ceramic and can withstand temperatures up to 1,800 degrees Fahrenheit (982 degrees Celsius) without damaging or losing their structural integrity.
There are several types of refractory bricks to choose from, each with its own unique properties and applications. Some common types include fireclay refractory bricks, alumina refractory bricks, magnesia-based bricks, etc.
Refractory clay bricks are made from a mixture of refractory clay and other materials, such as alumina and silica. They are known for their high resistance to thermal shock and are commonly used in applications such as furnace linings and fireplaces.
High alumina bricks are made from a mixture of alumina and other materials (e.g. silica). They are highly resistant to fire and are often used in furnace linings, kiln linings and other high-temperature equipment.
Refractory bricks are also classified into different grades according to their resistance to acid, alkali and neutral. Acid-resistant bricks are used in acidic slag environments, alkaline bricks are used in alkaline slag environments, and neutral bricks are used in neutral slag environments.
We have been specializing in producing bricks with different designs, colors, and sizes for half a century.
At present, SBCD member of a brick home company with the benefit of experienced workers and experts with their professional use of modern European technical knowledge and machines, as well as obtaining quality and management standards, is expanding its share in regional and world markets for its manufactured products.
Brick production has been done in the same way all over the world for centuries. Briefly, we could say that this process involved soiling, molding, drying, and finally, creating bricks. Factors such as the London Fire of 1666 and the Industrial Revolution made people recognize brick as a refractory and fire-resistant material. Hence, the consumption of brick became more popular.
But today, we use the most modern equipment and fully automatic brick production machines and produce bricks by European standards.
alumina bricks manufacturer, producing high-quality alumina bricks. we have professional engineers and advanced technical guidance. We also have a lot of export experience. We can export cheap alumina bricks
Alumina bricks are a common refractory material and contain more than 48% alumina. They are neutral refractory materials. The bricks are made from bauxite or other high alumina raw materials by molding and firing. They have high thermal stability and can withstand high temperatures above 1770 C. alumina bricks are characterized by high refractoriness, high strength, resistance to acid attack and good thermal stability. alumina bricks are mainly used as linings for building electric iron furnaces, glass kilns or cement rotary kilns.
magnesia carbon bricks . Our high volume output, combined with stringent manufacturing methods, has made us a strategic
Magnesia carbon brick is a no-burn alkaline refractory material. It enhances corrosion resistance and slag resistance. The product range is based on magnesia composite materials. These bricks show excellent resistance to thermal shock and corrosion at high temperatures and are widely used in the steel industry. Its high melting point and resistance to hydration make it an ideal refractory material. Steelmaking requires extreme chemical, thermal and mechanical conditions that require materials with high performance that can withstand the action of steel and slag. Both magnesia carbon and magnesia alumina carbon are capable of providing such properties.
In addition to manufacturing standard brick sizes (MC 8/10/12/14/18), we are able to produce specialized shapes to suit all reformer and electric arc furnace designs.
High alumina brick refers to refractory products with Al2O3 content higher than 48%.It is made of bauxite or other raw materials of high alumina content .The refractoriness of high alumina brick can be more than 1770 C .
According to the content of Al2O3, high alumina bricks are usually divided into three grades: Grade I Al2O3 content 75%; Grade II Al2O3 content is 60 75%; Grade III Al2O3 content is 48~60%.
Application:
High alumina bricks are mainly used for lining blast furnaces, hot blast furnace, electric furnace roofs, blast furnaces,reverberatory furnaces, and rotary kilns.

Anti-Corrosive Carbon Bricks
Anti-corrosive carbon brick is made by a unique technological process from high-quality carbon-containing materials and acid-proof organic compound, which is shaped under high pressure and bonded by high-strength gum. It, with excellent acid-resistance, is a kind of ideal lining material for the large acid-proof and corrosion-resistant vessels in chemical and metallurgical industry. It is green environment protected products.
Characteristics
Acid proof and corrosion-resistance
Using high-grade carbon-containing materials and adding acid proof organic compound, it, with low porosity and high bulk density, is so hard to be corroded by acid or alkaline solution.
High temperature resistance, long lifetime
It has much higher proof high-temperature of top to 350�°C and abrasion-resistance than traditional rubber products. It has scarcely any change with temperature going up due to its bonding and additive. So, its lifetime is long.
Accurate dimensions
It can fully satisfy the requirements of constructionâ??s technology because the brick has properties of high quality of shaping and accurate dimensions. We can also manufacture specific form bricks with customersâ?? requirement.
Typical application
The lining of phosphoric acid reactor
The lining of acid-washing launder
The lining of carrying phosphate acid storage can and hydrochloric acid storage can in railway industry
The lining of desulphurizing tower of exhaust gas and chimney in power plant
