Special-shaped refractory bricks are made from raw materials such as stone powder and slime,Refractory Bricks which are fired in a kiln at around 1300°C. Special-shaped refractory bricks do not have a certain shape and size of refractory materials. We usually divide it into fired bricks,Refractory Bricks unfired bricks, fused bricks (fused cast bricks),Refractory Bricks and refractory and insulating bricks according to the preparation process. Special-shaped refractory bricks are a common refractory material. There are many types of special-shaped refractory bricks. According to their different materials,Refractory Bricks they can be divided into clay and high-aluminum special-shaped refractory bricks, siliceous refractory special-shaped bricks,Refractory Bricks and magnesia and magnesia-aluminum special-shaped refractories. brick.
Special-shaped clay and high-alumina refractory bricks: under normal circumstances,Refractory Bricks the proportion of external dimensions is within 1:6, with no more than 2 concave corners (including arc-shaped concave corners),Refractory Bricks or with an acute angle of 50o to 70o, or with There are no more than 4 grooves (based on the total number) of clay refractory bricks weighing 2-15Kg and high alumina refractory bricks weighing 2-18Kg,Refractory Bricks named as clay and high alumina refractory special-shaped bricks.
Shaped siliceous refractory bricks generally have a ratio of outer dimensions within 1:5, with no more than 1 concave angle, or with an acute angle of 50o to 75o,Refractory Bricks or with no more than 2 grooves (according to the total number) ) The siliceous refractory bricks with a weight of 2-12Kg are named as siliceous special-shaped refractory bricks.
Magnesia and magnesia-aluminum shaped refractory bricks: Generally,Refractory Bricks all other magnesia and magnesia-aluminum products that cannot be included in the definition of general-shaped refractory bricks are named magnesia and magnesia-aluminum shaped refractory bricks. Special-shaped refractory bricks have the advantages of refractory bricks' high temperature resistance, abrasion resistance, slag resistance, etc.Refractory Bricks as well as the flexibility of production with unfixed shapes. It can be widely used as high-temperature building materials and structural materials for building kilns and various thermal equipment,Refractory Bricks and can withstand various physical and chemical changes and mechanical effects at high temperatures.
