Refractory bricks can be divided into multiple models and specifications according to their chemical composition, performance and use. The following is to introduce the firebrick model and specification.
First, the type of firebrick
Firebrick is a kind of important refractory materials, according to the chemical composition, performance and use of different, can be divided into several types. The following are common firebrick models:
1, silica refractory brick: mainly made of silicate, with high temperature stability, acid and alkali resistance characteristics of strong. Common models are S-65, S-70, S-75, etc.
2, high aluminum firebrick: mainly made of alumina, has the characteristics of good high temperature stability, strong corrosion resistance. Common models are AL-55, AL-60, AL-65, etc.
3, mullite refractory brick: mainly made of mullite, with high temperature stability, thermal shock resistance characteristics. Common models are M-80, M-85, M-90, etc.
4, magnesium refractory brick: mainly made of magnesium salt, has the characteristics of high temperature stability and strong anti-corrosion performance. Common models are MgO-C, MgO-Zr-C and so on.
5, corunalumina refractory brick: mainly made of alumina, with good high temperature stability, corrosion resistance characteristics. Common models include AZS-33 and AZS-36.
6, silicon carbide refractory brick: mainly made of silicon carbide, with high temperature stability, corrosion resistance characteristics of strong. Common models include SiC-90 and SiC-98.
In addition to the above common firebrick models, there are a variety of non-standard specifications and special materials of firebrick, according to the use of different occasions and needs to choose. At the same time, different specifications of firebricks can also be customized according to customer needs.
two. Specifications of firebricks
Refractory brick is an important refractory material with diverse specifications. The common specifications are as follows:
1, 230*114*65mm: also known as standard specification firebrick, this is the most commonly used specification, widely used in a variety of high temperature industrial kiln lining, flue, cooling wall and other parts.
2, 230*114*75mm: this specification of firebrick compared with the standard specification larger volume, weight is also heavier, usually used for some with higher technical requirements of industrial kiln lining and other parts.
3, 200*100*50mm: also known as small size firebrick, compared with the standard size smaller, suitable for some details of the laying, such as flue elbow, transition section, etc.
4, other non-standard specifications: in addition to the above common specifications, there are a variety of non-standard specifications of firebrick, can be customized according to customer needs, such as rectangle, fan, trapezoid and other shaped specifications.
In short, different specifications of firebricks can be selected according to different use occasions and needs. At the same time, manufacturers will also provide different sizes of firebricks according to customer demand.
